Biogas on-farm: energy and material flow
Schäfer, Winfried

Objectives:
European countries are committed to reduce CO2 emission originating from fossil fuels. On-farm produced biogas may replace energy produced from fossil fuels and so contribute to achieve the target. Up to now only in Germany a greater number of on-farm biogas plants has been established. The data of these plants can be used to evaluate cost and benefit of on-farm biogas production in other European countries. This paper concerns the following questions: Which parameters of biogas plant construction and operation have an influence on profit and sustainability of biogas production on-farm?
Hypothesis:
A biogas plant integrated within a self-contained farm organism is economically more competitive and more sustainable than an industrial biogas production unit of a mainstream farm.
Method:
First, a model is established that describes energy and material flow of two farm types. Farm type one produces biogas from slurry of 100 adult bovine units (ABU) and 10% co-ferment. Biogas powers a diesel engine of 26 kW electric power capacity using 10% ignition diesel fuel. Electric power production covers farm consumption and the surplus is supplied to the main grid. Heat is used for the farm estate surplus remains unused. Farm type two produces the same amount of biogas, but uses a gas motor. Additionally the farm includes a glasshouse of 1000 m2 to make use of electric power surplus and heat surplus. Further, the exhaust of the gas motor substitutes CO2 fertiliser procurement to the glasshouse.
Second, cost and benefit analysis of biogas production and application is done using empirical data of the most recent biogas plant survey in Germany. These data are adjusted to Finnish conditions where necessary.
Third, parameter variation is employed to find out the sensibility of the most important variables in terms of marginal profit and interest yield of investment for the biogas plant.
Results:
Farm type one delivers a positive interest yield of 2,6 % under German conditions. Under Finnish conditions there is no profit possible. Concerning methane production the marginal profit sensibility decreases in the following order: dry matter of slurry > quantity of co-substrate > reactor efficiency in terms of CH4 kg-1 organic dry matter (oDM) > fermentation period > number of ABU. Concerning electric power and heat production the marginal profit sensibility decreases in the following order: Level of electric power compensation > efficiency of energy conversion methane to electric power > price level of fuel oil and electric power.
Farm type two delivers a positive interest yield of 8 % under Finnish conditions. Concerning methane production the marginal profit sensibility does not differ from farm type one except with regard to CO2 fertiliser costs. Concerning electric power and heat production the marginal profit sensibility decreases in the following order: price level of light and heavy fuel oil and electric power > efficiency of energy conversion of methane to electric power > process energy > heating energy and heating period of the farm estate > operating time in h d-1 of the gas motor.
Discussion:
The better economic performance of farm type two under Finnish conditions mainly bases on substitution of CO2 fertiliser by the gas motor exhaust gas. The interest yield is very sensitive on energy input prices; however less sensitive than the interest yield of farm type one in respect of electric power compensation level. Further use of reactor digestion residues as organic fertiliser may improve sustainability of farm type two.

Centrum för uthålligt lantbruk (CUL) vid SLU har initierat ett pionjärarbete att få igång deltagande forskning inom lantbrukssektorn i Sverige. I denna rapport beskrivs den läro- och förändringsprocess, de framgångar och svårigheter, som en av de grupper som ingår i CUL:s satsning genomgått och mött under sitt arbete med deltagande forskning. De resultat gruppens försök och praktiska arbete lett fram till presenteras också.
Rapporten är skriven av gruppens facilitator (Karin Eksvärd) efter att ha samtalat med gruppmedlemmarna enskilt och tillsammans om deltagarnas åsikter kring gruppens arbete och arbetsformer. Några av gruppdeltagarnas åsikter och uttalanden finns inlagda som citat i rapporten. Deltagarna har även haft möjlighet att kommentera rapporten under dess framtagande. Gruppens arbete har möjliggjorts genom att rådgivarna har arrangerat gruppens möten som kurser inom miljöstödsprogrammet. Det har varit ett givande och lärorikt arbete som fortsätter att öka vårt kunnande om ekologisk tomatodling, oss själva som grupp och sättet att arbeta. Vi hoppas att denna rapport skall inspirera fler lantbrukare, rådgivare och forskare att i högre grad samverka med varandra och att på detta sätt vidareutveckla svenskt lantbruk.

Optimising nutrition in organic tomato production
Thorup-Kristensen, Kristian
Nutrient turnover
Crop health, quality, protection

Greenhouses and coverings
The abstract describes experiments with different cropping systems for organic greenhouse production of tomatoes. In this experiment two main questions are adressed. As greenhouse tomato production is a very intensive monoculture production, problems with nutrient supply and balances are expected, and problems with soilborne pests and diseases are widespread. To counter such problems, we compare the normal method of soil grown tomatoes with systems where tomatoes are grown in compost filled boxes. This allows to control nutrient losses and prevent carry over of diseses and pests in the soil. We also study an intermediate system, where where tomatoes are established in compost filled boxes, but the roots are allowed to develop also in the soil outside the boxes. This system seems to combine the main advantages of growing either directly in the soil or in the closed boxes. The other main question is whether the high nutrient demand by the tomatoe crops can be met by plant based materials, rather than by animal manure. The results suggest that suggest that all or at least most of the nutrient supply can be based on plant residues.

Composting and manuring
Ved produktion af væksthuskulturer er der behov for tilførsel af meget store mængder næring. Da plantenæringsstoffer samtidig er en begrænset ressource i økologisk planteproduktion, kan det være vanskeligt at skaffe tilstrækkelig næring fra økologiske husdyrbrug, hvor gødningen til økologiske væksthuse hovedsagligt kommer fra. I ORCTOM-projektet er næringsmæssig kvalitet og struktur af kompost baseret på lettilgængelige planterester derfor blevet undersøgt.

Organic production of cucumber and tomato grown in composted plant material from field crops
Greenhouses and coverings
In greenhouse vegetable production, large amounts of plant nutrients are needed. In organic production this may cause problems. Plant nutrients are a limited resource in organic crop production, and it can be difficult to acquire the amounts needed. Large amounts of manure added to the soil can lead to nitrogen leaching. Since plant nutrition cannot be controlled as precisely as in conventional production, temporal quality problems can occur due to imbalance between plant nutrients.
These problems, in combination with large investments for converting greenhouses and the risk for build up of soil diseases and pests, have led to an interest in production systems with compost in limited beds. Here, the soil can be changed and the drainage water can be collected. Conversion of greenhouses to organic production is cheaper, as fewer changes are needed. However, growing crops in limited beds are often considered by many as conflicting with the basic ideas behind organic farming. The advantages of a large soil volume, where plants can find nutrients, trace elements and water, are not utilised.
A solution could be a combined system. Most of the compost is added to a limited bed, but the plants develop their root system both in compost and in the surrounding soil. The amount of compost can be reduced and thereby the leaching risk will be reduced. The drainage water can be collected, and the compost will be changed before each crop, so that it will not carry soil-borne pests and diseases.
The objective of the project is to:
Study existing organic greenhouse vegetable production systems.
Develop composts primarily based on plant materials, easily obtained from organic farms.
Develop and compare growing systems allowing the plants variable access to the greenhouse soil, and to study their effect on nutrient balance, leaching losses, crop production and quality.

Sustainable production of greenhouse vegetables with organic fluid fertilizer and mycorrhiza
Greenhouses and coverings
In the production of greenhouse vegetables, the decline of the wholesale price of tomato and cucumber has impaired the profitability of greenhouse enterprises. New species are sought for production to improve the profitability. In Finland only one quarter of the production of sweet pepper is domestic and the proportion of organic production is small. There is a remarkable market for domestic sweet pepper. However, the shortage of nutrients and water as well as the tolerance of stress are limiting the yield of sweet pepper.
In the organic greenhouse production commercial liquid fertilizers are used to insure the availability of nutrients during the formation of the yield. They are significantly more expensive than chemical fertilizers. The cost of supplemental liquid fertilizer could be reduced by developing a fertilizer based on animal urine. Urine is commonly available for free on farms. On the other hand, the sales of urine could when proven a functional liquid fertilizer, in principle make a significant source of income of the same order of the income from milk, when the price of urine would be derived from the price of the nutrients in the organic liquid fertilizers. Some entrepreneurs have already tried to use urine as a liquid fertilizer with great success.
In the greenhouse production the availability of nutrients, the uptake of water, the growth of plants, flowering and the tolerance of stress could be improved by mycorrhizal inoculation. Actually, almost all the plants cultivated in the greenhouse; vegetables, spices and berries (except cabbages e.g. rucola) benefit from mycorrhiza when the conditions for the function of these fungi are optimal. Because mycorrhiza supplies the plants especially with phosphorus there is not much use of mycorrhiza when the phosphorus content of the media is high. Mycorrhiza works best when the solubility of phosphorus in the media is low. On the contrary, a high nitrogen content does not impair the function of mycorrhiza.
From the Finnish soil, effective mycorrhiza strains have been isolated but these are not yet developed to commercial preparations. However, there have been positive experience of their advantages e.g. in spices, strawberry and flowers.
The aim of this part of study is to develop an animal originating affordable ecological liquid fertilizer for production of organic sweet pepper in greenhouses and clarify the feasibility of mycorrhiza inoculation in the production of spices and vegetables on different medias.
Materials and methods MTT Agricultural Engineering develops in co-operation with the University of Helsinki an animal urine originated liquid fertilizer suitable for organic greenhouse production. There is in the first phase of the research a test in a greenhouse lasting whole the production period (approx. 6 months) where 1) bovine urine as a supplemental fertilizer, 2) pig urine as a supplemental fertilizer, 3) a commercial organic liquid fertilizer by Biolan as a supplemental fertilizer, 4) media fertilized with chicken manure (natural fertilizer by Biolan) and 5) media fertilized with chicken manure (natural fertilizer by Biolan) with a commercial organic liquid fertilizer by Biolan as a supplemental fertilizer are tested. In the same greenhouse but in a separate test the effect of sea algal on the production of sweet pepper is studied. The treatments of the second phase are selected according to the results of the first phase. MTT Agricultural Engineering is responsible for planning the use of liquid fertilizer and installations of the instruments needed and participates in the reporting. The University of Helsinki is responsible for management of the test in co-operation with the enterprises.
MTT Laukaa Research and Elite Plant Station clarifies in co-operation with the University of Helsinki the effects of mycorrhiza inoculation on the growth and yield production of selected organic spices and lettuce. In the test there are four medias developed by Kekkilä. One of them is optimised in the respect of the function of mycorrhiza transplant and actually transplanted with it. The others are: one traditional, one under development and one is optimised in the respect of the function of mycorrhiza transplant but without mycorrhiza. In 2003 the use of mycorrhiza is clarified in pot lettuce, parsley, basil, balm, thyme and coriander. The media is blended with 5% of transplant by volume. The University of Helsinki carries out analyses related to nutrients, germination, growth and production. During the growth physical properties of the media are measured. MTT clarifies issues related to the function of mychorriza, such as colonization in the root. The function of mycorrhiza is also measured as the phosphorus content of the leaves, because in a functioning symbiosis the phosphorus content of the leaves is increased pronounced.
After the test the University of Helsinki and MTT Plant Production Research estimates compatibility of the media and growing methods with mycorrhiza. The medias in the second phase of the study are selected based on the experience gathered in the first phase of the study. Mycorrhiza tests are carried out with these medias at least in sweet pepper, maybe also in greenhouse strawberry and spices for second time. MTT produces larger amounts of the mycorrhiza inoculum (scale-up) to provide a larger use of the mycorrhiza.

I tre anni di sperimentazione hanno permesso di accertare l'efficacia dell'utilizzo dell'insetto impollinatore Bombus terrestris per distribuire antagonisti naturali di Botrytis cinerea. Le prove sono state condotte su fragola in coltura protetta ed hanno fornito risultati positivi sulla possibilità di attuare una difesa dal marciume dei frutti; distribuendo il fungo antagonista Trichoderma harzianum mediante bombi si è ottenuta, nel 2002, un'efficacia di copertura paragonabile a quella di un prodotto di sintesi.

Marktäckning med plast i samband med sådd av radodlade grödor
Crop health, quality, protection

Greenhouses and coverings
Problemet med ogräs i radsådda grödor är störst kring själva plantorna i raden. I ekologisk odling uppgår arbetsinsatsen för ogräsrensning till cirka 150 timmar/ha i sockerbetor och 300 timmar/ha i morötter. En fortsatt utveckling av ekologisk odling kräver nya metoder för kontroll av ogräsen med en radikalt minskad insats av arbetskostnader. Det danska företaget Holmgaard Innovation har tagit fram en maskin för plasttäckning av raden i samband med sådd av t.ex. sockerbetor. I några mindre undersökningar har utrustningen visat sig fungera så bra att det kan innebära ett genombrott för möjligheten att bekämpa ogräs utan insats av herbicider. Emellertid saknas fortfarande en del grundkunskaper om utrustningens förmåga att kontrollera ogräs, effekter på kulturväxtens groning och skadedjurspåverkan. Framtagandet av viktiga grunddata och en objektiv utvärdering av maskinen är förutsättningen för ett genombrott med ny såteknik i ekologisk odling. I ett mindre orienterade försök på Alnarp, med sockerbetor, lök och morötter, provades maskinen 2001 , men utan resurser att närmare följa upp resultaten. Morötter och lök kom upp med reducerat bestånd fast utan ogräs i raden, medan sockerbetorna grodde dåligt och konsumerades av fåglar p.g.a. sen sådd. Vi avser att undersöka sådd av en rad olika fröslag som sockerbeta, lök, morot, kål o.s.v. med den nya såtekniken. Denna undersökning görs i samarbete med konstruktören Holmgaard Innovation och utförs i den ekologiska odlingen på Alnarp under säsongen 2002 och 2003. I undersökningen utvärderar vi : teknisk funktion hos maskinen, bekämpningseffekter och artskillnader på ogräs, groning, uppkomst och vitalitet på olika fröslag, eventuella insektsangrepp. Undersökningen sker i form av ett kontrollerat fältförsök per år med statistisk behandling av de studerade parametrarna.

Con riferimento ai sistemi colturali ortofrutticoli meridionali, l’obiettivo della ricerca è quello di monitorare le principali tecniche di gestione del suolo adottate, di circostanziarne i principali elementi caratterizzanti e di individuare le tecniche più “critiche”, responsabili di limitare il grado di sostenibilità del sistema ed introdurre le strategie più efficienti per migliorarlo.
Su alcuni “casi studio”, rappresentati da sistemi colturali ortofrutticoli di pieno campo e di serra, saranno realizzati interventi volti a modificare e migliorare le strategie e le tecniche di gestione della fertilità del suolo oggi in uso. Obiettivo specifico è quello di introdurre, nei sistemi orticoli di campo e di serra, tecniche di minimo avvicendamento colturale, colture di copertura (es, sovesci) e l'impiego del compost di qualità.
Il progetto di durata triennale è articolato in 2 sottoprogetti. Il primo, che si pone l’obiettivo di sviluppare tecniche di produzione di substrati colturali idonei all’impiego nel vivaismo orticolo biologico, è coordinato dal dr. Fabio Tittarelli ed include 2 Unità Operative: U.O. 1 coordinata dal dr. Vincenzo Verastro (IAMB, Bari) ed U.O 2 (CRA-ISNP, RM). Il secondo è rivolto al miglioramento delle performances produttive e ambientali dei sistemi orticoli di pieno campo e di serra condotti secondo il metodo dell’agricoltura biologica, è coordinato dal Dr. Stefano Canali ed include 3 Unità Operative: U.O. 3 (Università di Catania, CT), U.O. 4 (Scuola Superiore S. Anna, PI) ed U.O. 5 (CRA-ISNP, RM) coordinate rispettivamente dal prof. Leonardo Cherubino, dal dr. Paolo Barberi e dal dr. Stefano Canali. Il Prof. Paolo Sequi è il responsabile del coordinamento generale ed assicurerà l'interazione tra i due sottoprogetti.

In laboratory and micro-plots simulations and in a commercial greenhouse, soil ammonia (NH3) and pH were manipulated as means to control soil-borne fungal pathogens and nematodes. Soil ammonification capacity was increased by applying low C/N ratio broiler litter at 1–8% (w/w). Soil pH was increased using lime at 0.5–1% (w/w). This reduced fungi (Fusarium oxysporum f. sp. dianthi and Sclerotium rolfsii) and root-knot nematode (Meloidogyne javanica) in lab tests below detection. In a commercial greenhouse, broiler litter (25 Mg ha−1) and lime (12.5 Mg ha−1) addition to soil in combination with solarization significantly reduced M. javanica induced root galling of tomato test plants from 47% in the control plots (solarization only) to 7% in treated plots. Root galling index of pepper plants, measured 178 days after planting in the treated and control plots, were 0.8 and 1.5, respectively, which was statistically significantly different. However, the numbers of nematode juveniles in the root zone soil counted 83 and 127 days after pepper planting were not significantly different between treatments. Pepper fruit yield was not different between treatments. Soil disinfection and curing was completed within one month, and by the time of bell-pepper planting the pH and ammonia values were normal.

Composting and manuring
Good quality transplants are vital to growers for a number of reasons. Their ability to better tolerate pest, disease and weed problems and their capacity to make better use of newly incorporated green manures (compared to direct drilling) make them all the more so in organic systems. The availability of high quality growing media is essential to producing healthy vigorous plants, but the organic standards restrict the choice of products available and many growers do not feel they have sufficient information to base their choices. OCW, with support from Farming Connect, coordinated a project to assess the certified products and looked at a green waste based product under development to help address this problem.
Growers were supplied with samples of certified products (details provided in the table below) and were asked to test them on range of crops. In order to support this work, scientifically robust trials were carried out by a plant raising specialist on cabbage leek and lettuce.

Im Ökologischen Gurkenanbau stellt Befall mit dem Erreger des Falschen Mehltaus (Pseudoperonospora cubensis) eines der bedeutendsten Probleme dar. Ziel des Projektes ist es, Strategieoptionen zu erarbeiten, die zur Eindämmung des Befalls mit Falschem Mehltau an der Gurke eingesetzt werden: a) Auswahl möglichst gering anfälliger bzw. toleranter Gurkensorten , b) Kulturführungsmaßnahmen für den Salatgurkenanbau unter Glas, c) biologische Alternativpräparate auf der Basis von Pflanzenextrakten und Mikroorganismen. Nach der Auswahl geeigneter Gurkensorten werden diese in Kombination mit Entfeuchungsstrategien bzw. in Kombination mit den biologischen Präparaten im Hinblick auf die Befallsreduktion mit Falschem Mehltau untersucht. Nach Optimierung der Kulturführungsparameter und der alternativen Präparate werden Kombinationen aller Maßnahmen eingesetzt. In jedem Jahr werden Versuche unter Praxisbedingungen durchgeführt. Die Anwendung der verschiedenen Strategien wird den jeweiligen Praxissituationen angepasst und verspricht dadurch sehr gute Erfolgsaussichten. Eine Übertragung der Ergebnisse in die Praxis wird zum einen durch die Anbindung an die Bioland-Beratung im anderen Teilprojekt, sowie durch Veröffentlichungen, Vorstellungen auf Fachseminaren und Tagungen sowie durch das Erstellen eines Anbauleitfadens gewährleistet.

Biocontrol of bacterial pathogens is effected by using cupric salts associate to appropriate agronomical practices such as seed certification, irrigation and fertilization.
In in vitro and in in vivo tests, aqueous extracts from Allium sativum and Ficus carica fruits reduce the survival and the damages (disease incidence and disease severity) caused by bacterial pathogens of kiwifruit (Pseudomonas syringae pv. syringae, Pseudomonas viridiflava) and of tomato (Pseudomonas syringae pv. tomato) plants. In vitro tests, both vegetal extracts show antimicrobial activity against all bacterial strains utilised at different concentrations (106 – 108 cfu ml-1). In vivo tests Allium sativum and Ficus carica extracts confirm their antimicrobial activity on P. s. pv. tomato reducing DI and DS after two weeks until to 60% and 67% and to 32% and 22%, respectively.

Energy use and Green house gas emission in organic agriculture
Halberg, Niels
Greenhouses and coverings
Reduction of fossil energy use has a two-fold aim namely reducing the dependence of a limited, non-renewable resource and reduction of emissions of green house gasses (GHG). Consumers interested in reducing their carbon footprint from food consumption may consider whether a shift towards eating organic foods will do the job? This involves two questions: Is organic food more energy efficient and –given that one is dedicated to eating organic – which products and which producers results in a lower GHG emission. From a farmer perspective it is interesting to know how the carbon footprint of the production may be reduced. Over time the principles for organic agriculture has included specific references to the question of reducing the use of non-renewable energy (Woodward & Vogtman, 2004) and this is still an explicit part of the objectives of the Danish organic farming movement.
It is, however, questionable to which degree these objectives have been achieved as regards the dependence on fossil energy in the present form of organic agriculture. The majority of farms still depend on fossil energy for traction and electricity and energy self-reliance seems not to be a major concern in practice. As regards fossil energy use, the major difference to conventional farming is that the rejection of chemical fertilizer reduces the indirect energy use in organic farming and that the yields are lower, thus reducing the solar energy captured in crops. However, as regards the emission of GHG the picture is more diverse and the net GHG emissions can be lower in organic agriculture compared with conventional.
The aim of this paper is thus to discuss the different perspectives of reducing energy use and GHG emissions from organic agriculture by presenting results regarding
· Different methods and results of comparison of energy use efficiency in organic agriculture
· The potential for energy savings and self-reliance in organic agriculture
· The relative importance of fossil energy use for emissions of GHG from production of different organic products
· The relative importance of different organic and conventional food items for the total GHG emission of food consumption

Raspberries for the fresh market is a new and very profitable crop in Norway, and the production in polyethylene tunnels is increasing rapidly. In Norwegian organic production, the experience so far is that using tunnels is a prerequisite if growing for the fresh market. The project focuses on the major bottlenecks in organic tunnel production of raspberries. The project will develop methods for controlling the most damaging pests (raspberry beetle, aphids and mites) and methods for secure and efficient supply of organic nutrients in tunnels. The research on raspberry beetle is a co-operation with Sottish Crop Research Institute.
An important task in this project is to extend the growing area for tunnel production further north, by utilizing the long coast of Norway. Main growing area for raspberries in Norway is in the Western part of Norway, (~ 61º N), where the climate has proved to be very suitable for raspberry production. Going further north along the coastline the summer gets cooler, but the winter climate is quite similar. In Nordland (65º N), the raspberries grow well, but the fruits get damaged of rain and wind annually. In Troms, (68º N), the temperature sum during growing season is too low for outdoor production, but tunnels may render raspberry production possible in Troms. The project will develop methods for early growth start, for protection against frost and for extending the season. Different types and combinations of covers and reflective mulches will be tested for that purpose. The project will also obtain more knowledge about climatic and environmental impact on fruit quality, and includes analyses of potential health beneficial components in berries, which is important for the future marketing of the crop. The methods researched in this project will also have a potential for use in conventional growing, and conventional as well as organic growers are participating.

Bodemkwaliteit is een containerbegrip dat biologische, chemische en fysische componenten omvat. Bodemgezondheid is een nauwer begrip dat beschreven kan worden vanuit een ecosysteem benadering. De begrippen stabiliteit en zelfregulatie, vitaliteit, ecologische veerkracht, organisatiegraad en biodiversiteit worden ten opzichte van elkaar gepositioneerd.
Ziektewerendheid is een weer nauwere invulling van het begrip bodemkwaliteit en heeft uitsluitend betrekking op het vermogen van gronden om, ondanks de aanwezigheid van pathogenen, de expressie van de pathogeen in het gewas laag te houden. Negen mechanismen waarop de ziektewerendheid gebaseerd kan zijn worden beschreven.
Het feitelijk vaststellen (meten) van ziektewerendheid gebeurt in biotoetsen met specifieke plant-pathogeen combinaties. Dat is duur en tijdrovend. Daarom wordt gezocht naar afgeleide indicatoren en parameters. Resultaten uit de literatuur worden gepresenteerd.
Uiteindelijk is het van belang of telers de ziektewerendheid daadwerkelijk kunnen sturen door teeltmaatregelen. Vijf (groepen van) teeltmaatregelen worden besproken.
In deel 2, ziektewerendheid tegen bodemgebonden schimmels, worden zes schimmelziektes meer gedetailleerd besproken.

In dit tweede deel van dit literatuuronderzoek naar bodemgezondheid in de biologische glastuinbouw is informatie verzameld over 6 belangrijke schimmelpathogenen die in de biologische vruchtgroententeelt van belang zijn: Fusarium, Phomopsis (zwartwortelrot), Pyrenochaeta (kurkwortel), Pythium, Sclerotinia (rattenkeutelziekte) en Verticillium. Behalve aan het herkennen van de ziekte en de ecol ogie van de pathogenen, is specifiek aandacht besteed aan mogelijkheden die biologisch werkende glastuinders hebben om met teeltmaatregelen de ziekten te bestrijden. Afhankelijk van het soort pathogeen zal de keuze op een andere set maatregelen vallen.
• Algemene maatregelen zijn het gebruik van compost of andere organische toevoegingen, en de introductie van wisselgewassen.
• Specifiekere maatregelen zijn het introduceren of stimuleren van antagonisten.
• Tenslotte zijn er nog maatregelen die als laatste redmiddel een plek hebben in de biologische teelt, zoals solarisatie, biofumigatie of stomen.
Ter afsluiting wordt in tabelvorm een samenvattend overzicht gegeven aan de teler met handvatten voor sturing op het gebied van bodemgezondheid.

Verbesserung der Produktionssicherheit und Verlängerung des Angebotszeitraumes durch Anbau von Öko-Erdbeeren im Folientunnel
Post harvest management and techniques
Fruit and berries
Greenhouses and coverings
Erdbeeren sind eine der am meist verkauften Früchte in deutschen Supermärk-ten. Regional erzeugte, konventionelle Erdbeeren sind von April bis November erhältlich. Auf nur 2,1 % der Produktionsflächen in Deutschland werden Erdbee-ren ökologisch erzeugt. Die Gründe hierfür sind vor allem in der geringen Trans-portfähigkeit und Haltbarkeit der Früchte, der momentan kurzen Anbausaison für ökologische Erdbeeren, eine geringe Motivation konventioneller Anbauer, auf ökologischen Anbau umzustellen und ein Mangel an erfolgreich umgestellten Be-trieben zu finden.
Eine bedeutende Erneuerung wird durch den Anbau von Erdbeeren im Tunnel anstatt im Freiland erwartet. Versuche hierzu wurden empfohlen und geplant.
Die Versuche werden sowohl auf den Flächen der Landwirtschaftskammer als auch auf Praxisbetrieben über drei Vegetationsperioden durchgeführt. Einmaltra-gende Sorten und Remontierer werden in einem Tunnel, unter einer Regenkappe und im Freiland angebaut. Die Versuche sollen zeigen, inwieweit die erwarteten Verbesserungen in der Produktbeständigkeit, im Ertrag und der Qualität der Früchte ausreichend sind für eine Verwendung handelsüblicher Tunneln in der ökologischen Erdbeerproduktion. Dabei werden verschieden Sorten getestet, Krankheit und Schädlingsbefall werden bonitiert und ökologische Bekämpfungs-maßnahmen entwickelt.
Wir erwarten, dass die Ergebnisse den Anbau von ökologisch erzeugten Erdbee-ren steigern und eine signifikante Erhöhung des Marktanteils von regional er-zeugten ökologischen Erdbeeren bewirkt.

Historische kennis: Bodem en bemesting in de kasteelt van weleer
van der Burgt, Geert-Jan
Soil
Greenhouses and coverings
Door middel van een literatuurstudie is gekeken naar kennis op het gebied van grondbewerking, beworteling en bemesting in de grondgebonden kasteelt in Nederland van 1945 tot 1975. Doel hiervan was het achterhalen van inspirerende kennis voor de huidige grondgebonden biologische bedekte teelt.
Er zijn binnen de wetenschappelijke literatuur weinig publicaties over grondbewerking en beworteling en meer over bemesting. Veel van de beschreven praktijken in de bedekte teelt zijn achterhaald en/of vervangen door heel andere en effectievere middelen. Dit wordt al toegepast in de biologische teelt. Ook de huidige kennis van de inzet van organische mest en compost in relatie tot de levering van mineralen is aanzienlijk groter dan die van destijds.
Wat resteert is het vraagstuk van structuur, beworteling en gewenste diepte van beworteling. Samengevat komt het er op neer dat diepere beworteling (50 – 70 cm) zeker voordelen heeft, maar dat het geen voorwaarde is voor een geslaagde teelt. Ondiepere beworteling maakt alleen dat de teler er dichter op moet zitten en minder kan overlaten
aan gewas en bodem zelf. Dit zou in onderzoek verder uitgewerkt kunnen worden.

Nitrogen balances in Dutch organic greenhouse production

Nutrient turnover
Farm nutrient management
Greenhouses and coverings
The organic greenhouse production in the Netherlands is limited with regard to the number of growers, but plays an important role in EU organic greenhouse production. In the high-technology greenhouses a high production level is realized but nitrogen balances of this production system have been questioned. In order to document and improve the nitrogen balance, the production of seven greenhouses was monitored and soils were repeatedly analysed. The model “Bemestingsrichtlijn biologische kasteelten” (Fertilization Guide Organic Greenhouse Production) has been developed to simulate nitrogen availability and to fine-tune manure applications to crop demand. In the course of four years the overall nitrogen surpluses decreased sharply, but due to the observational character of the research no statistical analyses can be made. Part of the high surpluses in the first years can be explained by initial investments in soil organic matter. Calculation of the dynamic balance gives more possibilities to fine-tune farmers’ fertilization strategies. Growers that followed the model-based advise for manure application, realized a substantial reduction of nitrogen surpluses.

Farm economics
The paper examines the profitability of twelve polytunnel vegetable crops grown for an organic box scheme in Scotland. All inputs attributable to specific crops, labour in particular, were recorded during 2008 growing season and expressed in monetary values. Costs of the tunnel construction and maintenance have also been included. Based on sales data and inputs, annual net margins were calculated. Assuming the cost of labour as 7.25 £/hour only five of twelve vegetables were profitable. Results varied from 25.2 £/m2/year for cucumbers to -9.7 £/m2/year (loss) for batavian lettuce, average for all the crops was 3.38 £/m2/year. No significant difference in profitability could be ascertained between the following cultural methods: direct sown versus transplanted and under black plastic mulch versus open ground.

Auch im ökologischen Anbau von Tomaten, Paprika und Auberginen werden vermehrt veredelte Pflanzen eingesetzt. Am Markt werden für jede Kulturart verschiedene Unterlagen angeboten. Am Kompetenzzentrum für den ökoloischen Gemüsebau in Bamberg (Bayr. Landesanstalt f. Wein- u. Gartenbau) wurden in 2007 hierzu umfangreiche Vergleiche durchgeführt. Es zeigte sich, dass die Wahl der Unterlage eine massive Auswirkung auf den Ertrag haben kann. Nicht alle Unterlagen sind für den Bioanbau gleich gut geeignet. Bei der Auswahl der passenden Unterlage reicht es keinesfalls die Resistenzen zu betrachten, auch andere Faktoren müssen Beachtung finden.

It is very much debated whether bioethanol is a sustainable energy resource that can offer environmental and long-term economic advantages over fossil fuels, like gasoline or die-sel. From the present first generation bioethanol technology focusing on starch (from grain) fermentation GHG savings are only modest. The Danish Integrated Biomass Utili-sation System (IBUS) has developed both first generation and second generation princi-pal bioethanol technologies characterised by integration with an existing coal-fired Com-bined Heat and Power (CBH) plant.
To secure that bioenergy is produced from local adapted raw materials with limited use of non-renewable fossil fuels there is a need for integrating the biomass starting point into the energy manufacturing steps. Substitution of fossil fuels by crop biomass requires the right selection of plant species according not only to chemical quality for efficient con-version but also to secure the development of ecologically benign farming system includ-ing biomass for energy.
The aim of the present study was to question how to optimise GHG savings for bioetha-nol production using the IBUS technology.

Why diversify annual biomass production for energy – exemplified by green house gas emissions from the Danish IBUS bioethanol production concept

Production systems

Air and water emissions
There is a need for integrating the biomass starting point into the energy manufacturing steps. It will secure that bioenergy is produced with limited use of non-renewable fossil fuel to secure that in the application of biomass a net emission reduction of green house gasses take place along the whole chain.
Intercropping, defined as the cultivation of two or more species simultaneously on the same area of land, is an traditional practice still widespread in the tropics and common in developed countries before the ‘fossilization’ of agriculture. This cropping strategy is based on the manipulation of plant interactions in time and space to optimize resource use and productivity. It is regarded as the practical application of basic ecological principles such as diversity, competition and facilitation (Hauggaard-Nielsen et al., 2007).
Cereal-legume annual intercropping show the possibility to increase input of leguminous symbiotic nitrogen (N) fixation into cropping systems reducing the need for fertilizer N applications (Jensen, 1996). Moreover, less need for pesticides are obtained due to improved competition towards weeds (Hauggaard-Nielsen et al., 2001) and less general damages on intercropped species by pest and disease organisms (Hauggaard-Nielsen et al., 2007). Intercropping is a more adaptive management practice as compared to the present arable crop rotations consisting mainly of sole crops.
Perennials like clover-grass intercrops or mixtures are obviously more diversified than traditional annual crops. Clover-grass leys are important in many agroecosystems today due to quality as feed for livestock, a high dry matter production (10 t ha-1 yr-1 unfertilized, where 95% of the N accumulation is N2 fixed by clover (Jørgensen et al., 1999) providing a nitrogen-rich residue, which may significantly reduce fertilizer requirements for the succeeding crop when mineralized (Hauggaard-Nielsen et al., 1998). Furthermore, clover-grass lays can be harvested several times a year and processed to ethanol throughout the year.
It is very much questioned whether bioethanol is a sustainable energy resource that can offer environmental and long-term economic advantages over fossil fuels, like gasoline or diesel. The aim of the present presentation is to debate the substitution of fossil fuels by crop biomass requiring the right selection of plant species according not only to chemical quality for efficient conversion but also to secure the development of ecologically benign farming system including biomass for energy.

Farm nutrient management
The research cycle encompass year-long organic vegetable greenhouse production. Spring crop was grown pickling cucumbers followed by autumn tomato. During winter month without heating annual cover crops (mixture of oat, hairy vetch and field peas) were grown and as an green manure incorporated to the soil in spring before cucumber cultivation. Additional organic fertilizers (compost and chicken manure) were applied before cucumber and tomato planting. In the period between cucumber and tomato cultivation the soil in greenhouse was solarizated. In both crops soil surface was mulched with black fleece or fresh red clover biomass. Transplants of both species were produced in organic substrate. Cucumbers were planting in the soil but tomatoes in bottomless containers of 0,5 dm3, placed directly on the soil surface. The period of cucumbers growing was 90 days and tomatoes 120 days. Every 2 – 3 weeks in cultivation period nutrients concentration in soil solution was monitored on the depth of 30 and 60 cm. Growth development, earliness, yield and quality of fruits were determined. Red clover mulch positively influenced on cucumber and tomato growth and yield when applied early in the season, soon after transplant planting. In the initial period of plant growth (till fruiting) considerable amounts of nutrients (mainly nitrogen and potassium) were leached to the soil depth of 30 and 60 cm. After fruits setting and during fruits growth nutrient contents in soil solution considerably decreased and necessity of additional nutrients supply appeared. It was done by fertigation. In Polish climate condition soil solarization in summer months decreased the total number of soil microorganisms and was more effective while good insolation.

The development of organic protected cultivation taking place in densely populated areas has raised the question whether it is an environmentally friendly production system. The present study investigated energy consumption of organic pear production in two production systems, namely in traditional Chinese solar greenhouse and in the open field. In both production systems, energy output/input ratio and energy productivity were used as indicators to determine the energy efficiency; yield, cost of production, net economic return pear land area unit and benefit/cost ratio were used to evaluate economic productivity. The analysis results indicated that energy input and energy output in the solar greenhouse were higher than in open field per land area; whereas energy efficiency in terms of output/input ratio and energy productivity were lower in the solar greenhouse than those in the open field. However, if energy input sequestered in the protected structure was excluded in the solar greenhouse production system, energy efficiency was higher in the greenhouse system than the open-field system. Our analysis further showed that the economic costs, the yield, cost of production, gross product value and net incomes per land area unit in the greenhouse were more than twice as high as those in the open field due to a higher tree density and a premium price. However, the production taking place in open field used a great share of renewable energy and higher energy efficiency, which may comply more with the principle of organic farming than the greenhouse production system.

The work reports on a Garden Organic (working name of Henry Doubleday Research Association, Coventry UK) members experiment in 2007. Garden Organic members were surveyed with a detailed paper questionnaire to calculate an average gardening footprint of committed (self-selected) organic gardeners in the UK. This was used to develop a garden footprinting methodology and to create a benchmark of committed organic gardening in the UK. This was then compared to commerical orangic growing and to other household activities with their respective footprint and potential for improvement.
Summary findings:
(116 responses 85% reponse rate).
o The average UK food and drink ecological footprint is around 1.4 gha/ha
o About a quarter of this (25% =0.35 gha/ha) is due to fruit and vegetable production and consumption
o Our members taking part in this survey produced about half their own with an average ecological footprint for their gardening activities of 0.15gha/ha
o This equates to a ‘saving’ of around 0.02 gha/ha, or a saving of 13% on the average UK footprint attributable to fruit and vegetables
o This equates to about a 6% savings in total food and drink footprint which is on a par with double glazing, replacing an old boiler or reduced car use
o Our members could take measures to reduce their gardening footprint by:
- buying ‘good quality’ tools that last a long time
- using manual tools where possible
- buying ‘good quality’ power tools and keeping them well maintained to reduce relative fuel consumption and embedded energy costs
- by being wary of substituting long ‘food chains’ for long ‘supply chains’ of products that they use in their gardens
- by trying to close nutrient cycles; e.g. producing amendments at home (e.g. comfrey), fixing N in situ (e.g. green manures), composting biodegradable materials
- using protected cropping only where necessary and in an ‘environmentally friendly way’ e.g. reuse of materials, second hand strucutures etc.
- reducing fridge and/or freezer use; e.g. turning them off when not in use and buying new A++-rated energy-efficient appliances
o It is still uncertain what positive contributions waste and recycling can make in reducing gardening footprint as some of the issues are quite complex. Many are the subject of ongoing research.
o Producing food at home leads to other ecologically efficient habits as witnessed by the low overall ecological and carbon footprints of our members.
o It is important to realise that as you reduce your personal footprint the proportion due to services and infrastructure spent on your behalf becomes much more important. Solutions to this are likely to be collective and political. Many are likely to revolve around community based activities.

Netherlands
Knowledge management
The total area occupied in the Netherlands by organic horticulture under glass is growing steadily. Several growers convert to this form of horticulture every year and some existing organic growers are expanding their businesses. However, increasing imports from Spain and other south European countries, together with rising costs, means less room for economic development within this sector.
The report contains sector information, sector aspirations and current research projects.

Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods.
Legumes are not likely, in the short-term, to be used as monoculture crops for biorefinery feedstock, due to their relatively low DM yield. They are, however, important components of future diversified sustainable cropping systems that are not in direct competition with land for food production and can be production on marginal/surplus lands and degraded or drastically disturbed soils including production of biomass for non-food purposes to substitute fossil hydrocarbons. Perennial legumes (alfalfa, clover, various tree and shrub species) as sole crops or mixtures with grasses could have a unique role in producing biomass for biorefinery and simultaneously building soil organic matter and fertility without the requirement for N-fertilization
Future sustainable agricultural systems require novel solutions for agriculture to help society with climate change mitigation producing biofuels, materials and chemicals. One of the key paradigms for future sustainable agriculture is multifunctionality of system and crops. Agriculture must supply several services from the use of the same piece of land and the key principle to obtain this is diversity time ond space involving cropping systems as well as crop species. Thus, legume species, with their multiple arrays of potential services should be an important component of future sustainable agricultural systems for human prosperity.

A bovine manure compost (BMC) and a green compost (GC) were evaluated as components of substrates in partial substitution of peat for organic melon seedlings production. Treatments, differentiated on the basis of the volume percentage of the two analysed composts, were compared to the control (a mixture of peat, coconut fibre and perlite). In order to respect the guidelines of organic production, all the treatments were fertilised, at the beginning of the trial, with guano. Compost-based substrates were analysed for physical, physicochemical and chemical parameters (bulk density, porosity, pH, EC, nutrients content etc.). Even though significant differences were observed, recorded values were in the range of acceptability for growing media. In terms of performance, seedling growth in treatments containing 30% and 50% of composts was significantly higher than in control.

Health issues and environmental concerns have drawn the attention to organic agriculture aiming to protect the natural balance and to produce without damaging the environment. This study aims determining economic feasibility of organic greenhouse lettuce (Lactuca sativa L.) in an on farm trial, to foster organic greenhouse vegetable production in the preservation area of Tahtali Dam, projected as the sole water resource of Izmir,Turkey’s third largest. A 384 m2 greenhouse, constructed of galvanized metal tubing anchored and covered with a polyethylene was analyzed to identify typical operation procedures,and to determine unitary construction and operation cost. Organic lettuces were produced during autumn season of 2001-2002, testing different organic fertilizer applications, including two rates of farmyard and poultry manure (30 and 50 t ha-1) with and without two organic fertilizers based on either bacteria or algae. Economical analysis was performed according to different organic fertilizer applications. Cost, yield, and price data were analyzed to determine the profitability of a typical operation. Net return obtained from organic lettuce growing ranged between us $ 0.376 and us $ 0.901 m-2, as a result of different fertilizer applications.

Biowisselkas: Bredere vruchtwisseling voor een gezondere bodem

In 2009 en 2010 is een praktijkproef uitgevoerd met een alternatief teeltsysteem in de biologische glastuinbouw. Het doel van het alternatieve systeem is het verbeteren van de bodemgezondheid, door verbreding van de vruchtwisseling. Dit moet gebeuren op een manier die economisch rendabe is. In het zogenaamde Köver systeem, worden de plantbedden ondergronds door middel van folie in compartimenten verdeeld. Op de ene helft van het plantbed worden vruchtgroenten geteeld, en op de andere helft van het plantbed kunnen antagonistische gewassen worden geteeld, of kan de gron braak worden gelegd. Paprika blijkt in het systeem veel last te hebben van de antagonistische gewassen, die veel licht wegvangen. Door de rijke grondsoort (locatie Tinte) en hoge temperatuur hebben de antagonistische gewassen (Tagetes patula c.v. Single Gold (Ground Control) en Capsicum annuum c.v. Snooker) een sterke groei. De opbrengst van de paprika loopt daardoor met 25% terug. Hoewel we in combinatie met braak geen opbrengstdaling hebben gemeten, was er wel veel wegval van stengels. Vervolgonderzoek kan meer duidelijkheid geven of de combinatie paprika en braak echt rendabel is. Tomaat produceert in het systeem in combinatie met braak hetzelfde als in een normale teelt. De aantallen pathogene wortelknobbelaaltjes (Meloidogyne incognita) nemen sterk af tijdens een jaar braak. Twee jaar braak heeft echter geen extra effect op de daling van de aaltjespopulatie. Aan het eind van de opvolgende tomatenteelt zijn de aaltjesaantallen echter weer sterk gestegen, dit onafhankelijk van de voorvrucht (paprika of braak). Wel zijn de wortels iets gezonder van tomatenplanten die geteeld zijn nadat de grond braak heeft gelegen. De gezondheidsverbetering is echter te klein om ook in een hogere opbrengst te resulteren. Het systeem vraagt een andere aanpak van de bemesting.

Farm nutrient management
Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods.
Legumes are not likely, in the short-term, to be used as monoculture crops for biorefinery feedstock, due to their relatively low DM yield. They are, however, important components of future diversified sustainable cropping systems that are not in direct competition with land for food production and can be production on marginal/surplus lands and degraded or drastically disturbed soils including production of biomass for non-food purposes to substitute fossil hydrocarbons. Perennial legumes (alfalfa, clover, various tree and shrub species) as sole crops or mixtures with grasses could have a unique role in producing biomass for biorefinery and simultaneously building soil organic matter and fertility without the requirement for N-fertilization
Future sustainable agricultural systems require novel solutions for agriculture to help society with climate change mitigation producing biofuels, materials and chemicals. One of the key paradigms for future sustainable agriculture is multifunctionality of system and crops. Agriculture must supply several services from the use of the same piece of land and the key principle to obtain this is diversity time ond space involving cropping systems as well as crop species. Thus, legume species, with their multiple arrays of potential services should be an important component of future sustainable agricultural systems for human prosperity.

Greenhouses and coverings
The effect of two different roofing systems in comparison to the open field (closed tunnel, rain shelter - open field) were investigated in a field experiment during the seasons 2009 to 2011 at the Chamber of Agriculture North-Rhine Westfalia, Station Cologne-Auweiler, Germany. Four shortday varieties ('Clery', 'Darselet', 'Elsanta' and 'Sonata') were used. Considered quality features were yield, behaviour of the fruit during storage, fruit quality such as fruit firmness and sugar- and acid contents. The yield of the shortday strawberries was highest in the tunnel for normal and cold temperatures; under hot conditions the yield was reduced. The rain shelter protects against freezing during cold periods and at high temperatures it reduces heat stress, so that the yield under the shelter was high. The lowest yield was found in open field. Fruits from open field decays fastest due to the influence of rain; fruits from rain shelter ranked between tunnel and open field. In closed tunnel fruits trends to result in higher quality. This was found in nearly all analysed parameters.

This study aimed to evaluate the effects on tomato yield and quality of three pruning systems (2, 3 and 4 stems) of grafted plants (cv. Vinicio and Multifort) used to prevent the incidence of soil diseases. It was also investigated if the two stems from nodes of the cotyledon leaves improved crop performance compared to the two stems from the first true leaves nodes. The experiment was conducted in the spring/summer season, under greenhouse conditions at NW Portugal, with a randomized block design with 3 blocks and the four pruning crop treatments.
Total yield was significantly increased for the double-stem tomato crop, without significant differences between both stem nodes position (26.5 kg m-2), compared to plants with 3 and 4 stems (19.5 kg m-2). The fruit grade between 57-102 mm represented 96.3% of total yield and this was similar for all plant treatments. Fruit quality was not influenced by the pruning systems and mean characteristics were: fruit firmness (1.0 kg), content of soluble solids (5.1°Brix), acidity (1.0 g 100 g-1), pH (4.4), dry mater content (4.9%), and unblemished fruits (90.9%). Higher yield and fruit quality from double-stem tomato plants offset the increased planting labour and higher plant cost, compared to the 3 and 4 stems grafted plants. The similar results obtained with double-stem plants from cotyledon leaves nodes and from the first true leaves suggest that the former plants should not be recommended due to the higher nursery pruning care they need.

A significant increase in the domestic organic market, especially in Buenos Aires city can be observed in Argentina. Horticultural products represent a large percentage of the total organic volume traded. Within these, increasingly evident interest in heritage type products, niche type or heirloom can be observed. As the development of these products is almost incipient, varieties of tomatoes were rescued to characterize its production profile for possible adoption by organic horticultural producers in the area of Buenos Aires. A greenhouse trial with 14 varieties of tomatoes was developed. They were: PeaceVein, Ildi Red and Yellow, Black Plum, Chadwick, Saint Pierre, Thessaloniki, TSW10, Platense Gentile, Money maker, Mars, Uco Plata and the hybrid Koyi (from TheRuiterSeeds) and Elpida (Syngenta). Phenological and reproductive characteristics and agronomic profile of each variety were evaluated. The results concluded that some varieties are suitable to be incorporated to the horticultural trade as a complement of organic vegetables in the Horticultural Greenbelt in Buenos Aires. The most important varieties were the Ildis ones, with attractive color and piriformis; Black Plum, an old mahogany ovate tomato variety; Chadwick, also known as very productive variety of tasty fruit. Those who need further research include tomato Platense Gentile and Uco Plata.

Organic production systems in Northern highbush blueberries

Fruit and berries
The production of highbush blueberries is increasing worldwide. Organic production of blueberries in Sweden is presently very limited but is expected to have a great potential to expand as the berries are popular and have a good shelf life. The fact that blueberries require acid soils raises several questions concerning suitable substrates in combination with mycorrhizal inoculation and fertilization in organic production systems. Field and pot experiments have been established during 2011 and 2012 with the aim of developing a sustainable production system for high quality organic blueberries. After the second experimental year, total fruit yields were similar for plants grown in a plastic tunnel and in the open field. Yields were not affected by the addition of 10% forest soil to the peat-based substrate. Inoculation with ericoid mycorrhizal fungi had little effect on shoot length in a greenhouse pot experiment. Blueberries may be particularly suitable for organic production as the need for fertilizers is low combined with a relatively low disease pressure on the blueberry crop in the Nordic countries. The Swedish blueberry production might be expected to expand in the near future. The development of a successful and resource-efficient growing system for organic blueberries may encourage new blueberry growers to chose organic production.

Entre janeiro e abril de 2000 foi realizado um experimento no campus da Universidade Federal de Pelotas, RS, com o objetivo de caracterizar a ambiência do abrigo plástico e verificar sua interação com o cultivo de meloeiro (Cucumis melo L.) sob adubação orgânica em comparação à adubação mineral. Foi utilizada uma estufa plástica tipo Túnel Alto, com área de 307,3 m2 e 941,3 m3 de volume, disposta no sentido Norte-Sul e coberta com PEBD de 150^ Foram testados 8 tratamentos à base de vermicomposto bovino, cinza de casca de arroz e adubo mineral, seguindo a recomendação oficial de adubação. A cultivar utilizada foi a híbrida Trusty SLS, conduzida tutorada, na densidade de 4 plantas.m'2, em canteiros cobertos com plástico preto de 50^. A semeadura foi realizada em 27 de janeiro, o transplante entre 24 e 28 de fevereiro e a poda nos dias 5 e 6 de abril. As variáveis meteorológicas internas foram medidas com equipamentos de leitura manual e sensores eletrônicos instalados na região central do abrigo, sendo estes conectados a um micrologger programado para fazer leituras a cada 10 segundos e agrupá-las em médias a cada 15 minutos. Os valores médios diários de radiação solar global, temperatura do ar e do solo e umidade relativa do ar foram 3675 Wh.m'2, 24,8°C, 26,2°C e 81% respectivamente. A distribuição horizontal da radiação global no abrigo não foi uniforme, sendo significativamente superior na metade Norte e lado Leste em comparação a metade Sul e lado Oeste. A transmitância média à radiação global foi de 84% e à radiação PAR de 76,6%. As radiações PAR e líquida representaram em média 43% e 53% da radiação global interna. O albedo variou de 0,24 nos estádios iniciais da cultura até 0,30 nos dias anteriores a poda, baixando para 0,19 no final do ciclo. A colheita foi realizada em 20 de abril, com duração do período semeadura-colheita de 85 dias e do período transplante-colheita de 57 dias. A maior produtividade média foi atingida pelo tratamento adubado organicamente com vermicomposto bovino e cinza de casca de arroz que supriu 100% das necessidades de N e K, com 3,85 kg.m'2 de frutos totais e 2,64 kg.m'2 de frutos comerciais. O padrão potencial de fruto obtido pela média de todos os tratamentos apresentou 736 g de massa e 377 mm de circunferência.

Tomat er etter potet verdens mest dyrkede grønnsak. I Norge utgjør tomat den største andel av grønsaksareal i veksthus. Det konsumeres ca. 7 kg tomat i året pr person både konvensjonell og økologisk dyrket. økologiske tomater utgjør 9 % av de økologiske grønnsaker, som er på markedet. Det finnes et stort utvalg av sorter og det er kommet flere økologiske frø til salgs. Noen av dem presenteres her. Krav til tomatsortene er blant annet robuste planter, avling og jevnhet. Det er både frø til kommersiell og privat bruk, så vel som frø til veksthus og til dyrking på friland.

Dyrking av økologiske tomater
Friis Pedersen, Susanne
Vegetables
Greenhouses and coverings
Dyrking av tomat kan starte med eget oppal av småplanter eller det kan kjøpes småplanter til utplanting. Utover oppstart er det nødvendig å vite noe om klimastyring, gjødsling og vanning, stell av planter og plantevern. Disse temaene beskrives kort her. Avslutning av kulturen med høst og lagring er det siste punktet, som også er vesentlig i tomatdyrking.

Greenhouses and coverings
Agurk er populært på smørbrød, i salatbar eller i gresk tzatziki - for å nevne noe. Hver nordmann spiser i gjennomsnitt 5 kg agurk i året. Agurkdyrking stiller krav til varme og areal. Et følsomt punkt er roten av planten, særlig i starten av kulturen. Biologisk bekjempelse og beskjæringsmetode må løpende vurderes underveis i sesongen. Forhold som avsetning, lagring og salg må også tenkes igjennom før oppstart. Disse emnene behandles i det følgende.

Alternative Frischgemüsekulturen für den ökologischen Gemüsebau durch den Einsatz von Folientunneln mit Schwerpunkt auf dem Winterhalbjahr
Markets and trade

Die Winterzeit war traditionell die Zeit des Kohlgemüses, da sich dieses gut lagern lässt und Vitamine und Nährstoffe zur Verfügung stellt. Dieser Trend ist jedoch in den letzten Jahren sowohl im ökologischen wie im konventionellen Anbau rückläufig, während die Nachfrage nach frischem Gemüse stetig zunimmt. Im Winterhalbjahr wird dieses entweder importiert oder in beheizten Gewächshäusern produziert. Beide Verfahren sind mit einem hohen Energieverbrauch verbunden, der unter dem Gesichtspunkt der immer weiter steigenden Energiepreise und des ökologischen Fingerabdrucks im ökologischen Landbau als ungünstig zu bezeichnen ist. Ziel des Projekts ist es daher, ein alternatives Frischgemüsesortiment für Produzenten zu entwickeln, mit dem diese ihre Angebotspalette aufwerten bzw. erweitern können.

Ökoloogisch wirtschaftende Gartenbaubetriebe wirtschaften nutzen vor allem im geschützen Anbau oft große Mengen an externen Inputs als Grunddünger (Kompost oder Wirtschaftsdeünder) und Ergänzungsdünger (z.B. organische Handelsdünger wie Federmehle oder Produkte aus der Lebensmittelverarbeitung. Der Einsatz dieser Düngemittel ist über die EU-Ökoverordnung(834/2007 und 889/2008) geregelt. Bisher ist wenige über die Düngestrategien ökologischer Gartenbaubetriebe im Unterglasanbau bekannt, es fehlen beispielsweise Informationen zum Einfluss des Düngemamangements auf Nährstoffbilanzen und den Status an pflanzenverfügbaren Nährstoffen im Boden. Aus diesem Grunde wurden 10 ökologisch wirtschaftende Gartenbau in Südwest-Deutschland (5 Mitglieder von Bioland e.V. und 5 Mitglieder im Demeter e.V.) semi-strikturierte Interviews durchgeführt, mit deren Hilfe Daten zu Nährstoffinputs und - outputs für die Jahre 2010-2012 gesammelt wurden. Basierend auf diesen Daten wurden Nähstoffbilanzen errechnet. Darüber hinaus wurden in 22 Gewächshäusern dieser Betriebe Bodenproben genommen und auf Gehalte an Makronährstoffen untersucht. Die Düngestrategien der Betriebe unterschieden sich nach Verbandsmitgliedschaft: Die Mitglieder im Demeter e.V. nutzten grunddüngungs-betonte Strategien, die in im Vergleich zu den Bioland-Betrieben hohen Bilanzüberschüssen an N, P, Mg, Ca und Na, geringeren Überschüssen an S und geringeren Defiziten in K und Cl resultierten. Dagegen stützten sich die Biolandbetriebe auf ein Ergänzungsdünger-betontes Düngemanagement, was zu niedrigeren Überschüssen an N, P, Mg, Ca und Na führte, aber starke Defizite an K und Cl schuf. Außerdem war der S-Überschuss auf den Bioland-Betrieben höher. Alle Gewächshäuser wiesen hohe bis sehr hohe Gehalte an pflanzenverfügbarem P und K im Boden auf. In Abhängigkeit von der Dauer der ökologischen Wirtschaftsweise konnte zudem eine Anreicherung an Gesamt-P festgestellt werden (r2=0,22*).

Tijdens de zomermaanden blijven tal van koepels leeg liggen daar een voor- en najaarsteelt over het algemeen het meest interessant is. Toch is braak veelal niet de meest interessante aanpak: de onkruiddruk neemt toe, er treedt in bepaalde gevallen woestijnvorming op wat nefast is voor het aanwezige bodemleven, en tijdens die periode wordt de koepel niet gevaloriseerd wat in een aantal gevallen niet oninteressant is. Doelstelling van dit project was een optimale en rendabele invulling bekomen van de koepel tijdens de zomermaanden, geschikt voor elk type bedrijf.

In de winter worden veel verse groenten vanuit het buitenland ingevoerd. Tegelijkertijd neemt de vraag naar regioproducten toe. In het praktijknetwerk wintergroenten.nl ligt de focus op afzet in de eigen regio en in ruimere zin de regio Nederland. Welke gewassen groeien in de winterperiode in een onverwarmde of licht gestookte kas? Zijn er mogelijkheden voor nieuwe gewassen en worden deze opgenomen door de markt? Om de ervaringen en kennis over de verschillende winterteelten verder te verspreiden is besloten om vanuit het praktijknetwerk deze brochure uit te geven. De nadruk ligt bij de teelt en noodzakelijke teeltkennis over de meest voorkomende winterteelten, maar ook acceptatie vanuit de markt en aandachtspunten bij de afzet van wintergroenten worden hierin meegenomen. Mogelijk stimuleert deze brochure de uitbreiding van biologische winterteelten en daarmee de verbreding van het aanbod in het groenteschap met aantrekkelijke wintergroenten uit eigen regio.

Sistemas de culturas sob diferentes manejos por longa duração alteram as formas de fósforo do solo?

The thesis objective was to evaluate the forms of accumulation and release of phosphorus from cover crops waste under long time of different soil management systems and its relationship with the soil phosphorus forms. The experiment was established in 1986 on an Oxisol in the IAPAR experimental station in Pato Branco, Paraná State, Brazil. The treatments consisted of six winter cover crops (blue lupine, vetch, oats, radish, rye and wheat) and the winter fallow treatment, cultivated under no-tillage (NT) and conventional (CT). In September 2011 were collected soil samples (0-5 and 5-10 cm) and the shoots of winter cover crops. Confected litterbags (0.2 x 0.2 m) were collected at 7, 14, 28, 56 and 112 days after the cover crops management. In the residues collected, we assessed the accumulation of C, N, P, and held the fractionation of P. In the soil samples, we made the separation of aggregates by wet way and in the original soil and aggregates we evaluated the content of total C, N, P, the P forms, and the acid phosphatase activity. The distribution of P forms in the cover crops tissue varies among species and their accumulation was a function of nutrient soil P availability, as in NT. But for all of them, the soluble inorganic P was the principal storage form. The release of P from plant residues depends not only on its rate of decomposition, but also on the content of total and soluble P. The vetch and rye have great potential to recycle soil P, and this amount of P should be considered when prescribing phosphorus fertilization for the culture implanted in sequence. However, the long term cultivation of different winter cover crops did not affected the soil P forms in highly weathered clay soils, managed under NT and CT. On the other hand, practices that favor the accumulation of organic residues on the soil surface as the NT system, increase the acid phosphatase enzyme activity and labile organic and inorganic P forms, besides the formation of larger aggregates, which have higher levels of C, N, total P and organic labile P.

As plantas de cobertura propiciam a proteção e a reciclagem de nutrientes do solo, como o fósforo (P). Contudo, o teor e as formas de acúmulo de P podem variar entre espécies e sistemas de manejo de solo. O objetivo do trabalho foi avaliar as formas de acúmulo de P no tecido vegetal de plantas anuais de inverno, manejadas sob Sistema Plantio Direto (SPD) e Cultivo Convencional (SCC). O experimento foi instalado em 1986 no Instituto Agronômico do Paraná, em Pato Branco-PR, sobre um Latossolo Vermelho aluminoférrico. Ele se baseia no uso de seis plantas anuais de inverno (trigo, aveia branca, centeio, ervilhaca, nabo forrageiro e tremoço azul) que foram manejadas sob SPD e SCC. Em maio de 2011 as espécies foram semeadas, sem o uso de fertilizantes, e em setembro de 2011 efetuou-se a coleta da parte aérea das plantas. No Laboratório de Química e Fertilidade do Solo da UFSM realizou-se o fracionamento de P do tecido vegetal, além da determinação dos teores de carbono total, nitrogênio total e P disponível do solo. A partir dos dados obtidos, conclui-se que as formas de acúmulo de P no tecido das plantas anuais de inverno variam em função da espécie e da disponibilidade de P no ambiente; para todas as plantas anuais de inverno o P inorgânico solúvel é a principal forma de acúmulo de P no tecido vegetal, principalmente quando são cultivadas em solos com maior disponibilidade de P, como sob SPD; Em ambientes com baixa disponibilidade de P, plantas anuais de inverno tendem a diminuir as formas solúveis de P e, ao mesmo tempo, acumular formas orgânicas estáveis, principalmente na forma de Prna e Plip.

A manutenção dos resíduos vegetais sobre o solo, o tipo de resíduo e sua velocidade de decomposição são de grande importância no estudo da ciclagem de nutrientes. Este estudo foi desenvolvido na área experimental do IAPAR - Pato Branco-PR, onde foram avaliados seis resíduos de coberturas de inverno: tremoço azul (Lupinus angustifolius L.), ervilhaca comum (Vicia sativa L.), aveia preta (Avena strigosa S.), nabo forrageiro (Raphanus sativus L.), centeio (Secale cereale L.) e trigo (Triticum aestivum L.), sob Sistema Plantio Direto (SPD) e Sistema Cultivo Convencional (SCC) em um Latossolo Vermelho aluminoférrico. Foi avaliado: velocidade de liberação de potássio (K), matéria seca remanescente (MSR) em bolsas de decomposição, teor de carbono orgânico (Corg), potássio total (Kt) e nitrogênio total (Nt). O centeio foi a planta que apresentou a maior produção de matéria seca, o maior acúmulo de potássio ocorreu na ervilhaca sendo seu valor 2 e 2,4 vezes maior que no centeio e no trigo, respectivamente. A velocidade de liberação foi maior para todas as leguminosas em relação às gramíneas, sendo velocidade inicial rápida (entre 0 e 28 dias) e ao diminuindo longo do tempo.

O sistema de manejo pode afetar a disponibilidade de nutrientes para as plantas, em decorrência do sistema de rotação de culturas e da quantidade de resíduo vegetal presente na superfície do solo. O objetivo deste trabalho foi avaliar a quantidade de nitrogênio (N) e fósforo (P) acumulados no tecido vegetal de aveia preta, trigo, centeio, ervilhaca, nabo e tremoço azul, além de verificar seu estado nutricional de N e P. O experimento esta instalado no Instituto Agronômico do Paraná (IAPAR) em Pato Branco, Paraná, em um Latossolo Vermelho aluminoférrico. Em maio de 2011 os tratamentos foram semeados, sendo seis plantas de cobertura: trigo, aveia preta, centeio, ervilhaca, nabo forrageiro e tremoço azul cultivados sob Sistema Plantio Direto (SPD) e Sistema de Cultivo Convencional (SCC). Em setembro de 2011efetuou-se a coleta do material verde da parte aérea, o qual foi seco a 65ºC e posteriormente digerido com uma mistura de H2SO4 e H2O2, onde foram determinados os teores de nitrogênio total (Ntotal) e fósforo total (Ptotal), também foi quantificado o teor de carbono das amostras, e por fim calculou-se o índice de nutrição de fósforo (P índex) e de nitrogênio (N índex). Realizou-se a comparação das médias das plantas anuais de inverno e dos sistemas de manejo de solo por meio do teste de SCOTT-KNOTT. O sistema de cultivo influencia no acúmulo de N e P, consequentemente no índice de nutrição dos mesmos, sendo maior no SPD. A ervilhaca e centeio possuem grande capacidade de reciclar P.

O objetivo do presente trabalho foi avaliar a liberação de P a partir da decomposição dos resíduos de plantas de cobertura. Em setembro de 2011, em um experimento instalado em 1986 sobre um Latossolo Vermelho aluminoférrico, no IAPAR, Pato Branco, PR, foram coletadas amostras da parte aérea das plantas de cobertura tremoço azul, ervilhaca comum, aveia branca, nabo forrageiro, centeio e trigo, manejadas sob SPD. Mediu-se a decomposição dos resíduos das plantas e a liberação de P por meio de bolsas de decomposição de poliéster, que foram coletadas aos 0,7,14,28,56 e 112 dias após o manejo das plantas. Avaliaram-se as taxas de decomposição e o tempo de meia vida da MSPA e do P. O delineamento estatístico utilizado foi de blocos casualizados com três repetições. Realizou-se a análise da variância e a comparação das médias por meio do teste SCOTT-KNOTT a 5% de probabilidade de erro. Verificou-se que a quantidade de P liberado dos resíduos das plantas não é dependente apenas da sua taxa de decomposição e do seu teor total de P. A ervilhaca comum e o centeio reciclaram a maior quantidade de P do solo, pois a primeira possui a maior capacidade de acumular P no tecido associado a um tecido com elevada taxa de decomposição, enquanto a segunda produziu elevada quantidade de MSPA. A liberação de P dos resíduos de plantas de cobertura deve ser levada em consideração para reduzir o uso de fertilizantes fosfatados nas culturas cultivadas em sequência.

O fósforo (P) orgânico é importante fonte de fosfato para as plantas, tanto em ambientes naturais quanto em solos cultivados. O cultivo de plantas com alta capacidade de reciclagem de P pode aumentar a importância das formas orgânicas na disponibilização de fosfato, especialmente quando o solo não é revolvido O presente estudo objetivou avaliar em um solo muito argiloso sob longo período de cultivo (i) o efeito de diferentes preparos de solo e (ii) o efeito do cultivo de diferentes espécies de plantas de inverno, no teor de carbono e fósforo orgânico do solo. Em 1986 foi estabelecido o experimento com seis tratamentos de inverno (tremoço azul, ervilhaca peluda, aveia preta, nabo forrageiro, trigo e pousio) implantados num Latossolo Vermelho Aluminoférrico na região sudoeste do Paraná, sob sistema plantio direto (SPD) e sistema de cultivo convencional (SCC). As amostras de solo foram coletadas em outubro de 2009 em cinco profundidades (0-5, 5-10, 10-20, 20-30 e 30-40 cm). Sistemas de manejo do solo conservacionistas, como o SPD, aumentam o teor de carbono e fósforo orgânico total do solo da camada superficial comparativamente ao SCC, mas não é suficiente para recuperar os teores de carbono orgânico total original do solo sob mata nativa. O cultivo de plantas durante o inverno aumenta o teor de carbono orgânico total do solo independentemente do sistema de manejo de solo adotado, mas não altera o teor de P orgânico total do solo estimado pelo método de ignição.

Organic phosphorus (P) is an important source of phosphate for plants both in natural environments and in cultivated soils. Growing plants with high P recycling capacity may increase the importance of organic forms in phosphate availability mainly in undisturbed soils. The aim of this study was to evaluate the effect of long period of cultivation of different winter species under different soil management systems in the distribution of soil organic P forms, in the P content stored into the soil microbial biomass (SMB) and in the acid phosphatase enzyme activity. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) implanted in a Rhodic Hapludox in southern Brazil, under no-tillage system (NT) and conventional tillage system (CT). The crops were cultivated with rational use of chemical phosphate fertilizer, according to plant needs and soil type
maintaining high levels of soil organic carbon leading to P organic form accumulation. Growing crops during the winter period in highly weathered subtropical soil increases the importance of microbial interactions in the P cycle, especially in the NT, where a large amount of crop residues is annually added to the soil surface, increasing soil organic P level, P content stored into the SMB and acid phosphatase enzyme activity.

Soil organic matter (SOM) constitutes the largest reservoir of carbon (C) and nitrogen (N) of the earth's surface. In agricultural soils, the organic fraction is of great importance in maintaining soil quality, while contributing a small fraction. Thus, the adoption of soil management practices and cover crops are important to promote the C and N accumulation in the soil and consequently improve its quality. The no-tillage system (NT) as conservation practice improves the soil structure, water infiltration and increases the contribution of C and N in the soil by deposition of crop residue on the surface. Thus, the soil is kept constantly covered by organic residuce of plants during their vegetative stage. This study aims to evaluate the stocks of C and N in the profile of a very clayey soil. The winter cover crops were grown under two management systems i. e., NT and conventional-tillage system (CT) in an long-term 26 years experiment. The experiment was started in the winter of 1986 in an Oxisol rich in aluminium, in southwestern Paraná at the Agronomic Institute of Paraná, with eight winter treatments (oat, rye, vetch, hairy vetch, wild radish, wheat, blue lupine and fallow). The collection of the soil samples was conducted in November 2012 at the following depths: 0–5, 5–10, 10–20, 20–30, 30–40, 40–60, 60–80 and 80–100 cm. A soil samples were collected under native forest from an area adjacent the experimental area serving as control. The soil C and N contents through the elemental analyzer. After 26 years of cultivation, the soil under NT showed the highest levels and stocks of C and N in the surface layers compared to the CT. However, below 20 cm and even upto 1 meter depth, the soil C and N stocks did not differ between the soil management systems. Regarding the use of different plant cover, these treatments did not differ in stocks of C and N in both management systems (NT and CT).

The soil management systems cause changes to the aggregation and the stock of soil organic matter (SOM). The aim was to evaluate the influence of the winter cover crops and the tillage systems in aggregation and carbon (C) stock in soil and SOM fractions. The experiment started in 1986 at the Agronomic Institute of Paraná, in Pato Branco, in an Oxisol. The treatments are a combination of winter cover crops: black oat, rye, hairy vetch, common vetch, oilseed radish, blue lupine, wheat and fallow, and tillage systems: no tillage (NT) and conventional tillage (CT), in split plot design with three replications. Soil samples were collected in November 2012, in layers 0-5, 5-10 and 10-20 cm. In study 1, the aggregate stability were performed through wet sieving for determination of the mean weight diameter (MWD) and the aggregate distribution in diameter classes, and also the organic carbon (OC) in the aggregate. In study 2 only samples of plots black oat, oilseed radish and fallow, under NT and CT, were used in performing the density fractionation of SOM to obtain the free particulate organic matter (free-POM) and occluded particulate organic matter (occluded-POM) was performed. The concentration of C in soil and in free- POM and occluded-POM were analyzed by dry combustion, but the C concentration in mineral-associated organic matter (min-OM) was obtained by calculating the difference. The stock of C in soil and fractions of SOM and carbon management index (CMI) were calculated. In study 1, for all layers, the soil under NT had higher amounts of large aggregates that CT, which resulted in higher MWD of aggregates. The winter cover crops had no significant influence on the MWD of aggregates. The NT showed higher OC content of aggregates for the three diameter classes in the 0-5 cm layer compared to the CT. The highest levels of OC were found in the diameter classes >2 and <0.25 mm in the three soil layers. In study 2, for the 0-5 cm layer, the NT had higher C stocks in soil, free-POM and occluded-POM compared to CT. And for winter cover crops, the soil with radish had the highest C stock for the free-POM in the surface layer. The min-OM promoted greater accumulation of C for all management systems and soil layers. The NT promotes an increase in the aggregation and soil C stock, and it enables greater action of protection mechanisms of SOM, indicating the higher quality of this system compared to CT.

A matéria orgânica relaciona-se com os atributos físicos, químicos e biológicos do solo, e seu estoque é dependente do tipo de solo, das condições climáticas e dos sistemas de manejo adotados. Este estudo teve por objetivo avaliar a influência do cultivo de plantas de cobertura de inverno e de sistemas de preparo no estoque de carbono (C) no solo. O experimento iniciou no ano de 1986 no Instituto Agronômico do Paraná, em Pato Branco, sob um Latossolo Vermelho aluminoférrico. Os tratamentos analisados são uma combinação entre plantas de cobertura de solo [aveia preta, nabo forrageiro e pousio], e sistemas de preparo [plantio direto (PD) e preparo convencional (PC)], dispostos em parcelas subdivididas com três repetições. As amostras de solo foram coletadas em novembro de 2012, nas camadas de 0-5, 5-10 e 10-20 cm. O C no solo foi determinado por combustão seca em analisador elementar CHNS Euro Vector EA3000 e a densidade do solo através de amostras indeformadas de solo coletadas em anéis volumétricos. O cálculo do estoque de C foi realizado considerando as camadas analisadas. Os dados foram submetidos a análise da variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade, utilizando o programa computacional Assistat. Os efeitos ao estoque de C do solo foram mais pronunciados na camada de 0-5 cm e para os sistemas de preparo, sendo que o PD promoveu maior estoque de C (25,75 Mg ha-1) comparado ao PC (20,77 Mg ha-1) nessa camada. Não foi verificada interação significativa entre plantas de cobertura e preparo de solo. Para as camadas de 5-10 e 10-20 cm não houve diferença entre os preparos de solo. Além disso, as plantas de cobertura do solo não diferiram quanto ao estoque de C para as camadas de solo analisadas. Devido a mínima mobilização e manutenção dos resíduos vegetais na superfície do solo, o PD promove maior estoque de C na camada superficial do solo, o que ressalta a importância das práticas de conservação do solo para evitar a degradação e as perdas de solo, nutrientes e matéria orgânica desta camada.

A matéria orgânica do solo (MOS) relaciona-se com as propriedades físicas, químicas e biológicas do solo, sendo que seu estoque é influenciado pelos manejos do solo. O objetivo deste estudo foi avaliar a influência do cultivo de plantas de cobertura e de sistemas de preparo, no estoque de carbono no solo e nas frações físicas da matéria orgânica. O experimento iniciou em 1986 no Iapar, em Pato Branco, sob um Latossolo Vermelho aluminoférrico. Os tratamentos analisados são uma combinação entre plantas de cobertura de solo [aveia preta, nabo forrageiro e pousio], e sistemas de preparo [plantio direto (PD) e preparo convencional (PC)], dispostos em parcelas subdivididas com três repetições. As amostras de solo foram coletadas em novembro de 2012 na camada de 0-5 cm. A separação das frações físicas da MOS foi realizada através do método de fracionamento densimétrico da MOS. O carbono no solo foi determinado por combustão seca e a densidade do solo através de amostras indeformadas. O cálculo do estoque de carbono foi realizado considerando as camadas analisadas. O PD obteve os maiores estoques de carbono para as frações FLL, FLO e para o carbono total em relação ao PC. O nabo obteve o maior estoque de carbono em relação ao solo cultivado com aveia e o solo mantido em pousio hibernal com relação a FLL da MOS. Pode-se concluir que os sistemas de manejo interferem no estoque de carbono das frações leves da MOS, apesar de ser a FP a mais expressiva em estoque de MOS.

In de biologische glastuinbouw is een goede bodemgezondheid van cruciaal belang. Het streven is om een systeem te ontwikkelen met meer veerkracht en een betere bodemweerbaarheid. In dit onderzoek wordt het bodemleven gevoed met lignine-rijke gewasresten. Het doel is om de natuurlijk voorkomende witrotschimmels te stimuleren die lignine omzetten, en daarmee ook de overlevingsstructuren (microsclerotiën) van plant-pathogene Verticillium schimmels af te breken. Houtige gewassen bevatten het meeste lignine, gevolgd door grassen en granen. Ook gewasresten van broccoli en boon bevatten relatief veel lignine. In een laboratorium proef is grond van twee bedrijven met een natuurlijke besmetting met Verticillium dahliae gemengd met 7 lignine-rijke gewasresten. De twee gronden reageerden verschillend. Op locatie Schalkwijk (rivierklei) hadden maïsstengels, broccoli, rietstengels en Japanse haver (Avena strigosa av. astrigosa) een significant effect op de hoeveelheid levensvatbare microsclerotiën in de bodem. In 4 weken is in de variant met 10% (m/m) maïsstengels de hoeveelheid Verticillium met 69% afgenomen ten opzichte van de controle. Op locatie Tinte (zeeklei) hadden alleen rietblad en rietstengel een significant effect. Door toevoeging van rietblad (10% m/m) neemt de hoeveelheid Verticillium met 66% af. Op locatie Tinte is er een significante relatie tussen de hoeveelheid toegevoegde lignine en de afname van het aantal microsclerotiën van Verticillium. Voor locatie Schalkwijk is dit verband niet gevonden, hier spelen mogelijk andere mechanismen een rol. In de potproef is 1, 2 en 10% (m/m) riet en 2% tarwestro ingewerkt in van nature met Verticillium besmette grond. Na 12 weken zijn in de variant met 2% riet 75% minder microsclerotiën van Verticillium aanwezig dan in de controle, maar deze afname is niet significant. Resultaten van real-time PCR analyse laten echter wel een significante afname van de hoeveelheid Verticillium zien, in de varianten waar 1% en 10% riet is ondergewerkt. Bij toenemende percentages riet, neemt ook de immobilisatie van stikstof significant toe. Stro veroorzaakt meer immobilisatie dan riet. In de praktijkproef is 2% (m/m) riet ondergewerkt. Na 3 weken is er op het perceel paprika geplant. Na in totaal 12 weken is de afname van de hoeveelheid Verticillium bepaald. Uitplaten laat een lichte stijging zien van de hoeveelheid Verticillium in de controle, terwijl in de behandeling met 2% riet de hoeveelheid Verticillium afneemt. Deze verschillen zijn echter niet significant. Bij de real-time PCR analyse zien we een significant effect van het bemonsteringstijdstip. In december is er meer DNA van Verticillium in de bodem dan in maart. Dit is echter ook in de controle het geval. Er is dus geen significant effect meetbaar van het toevoegen van de gewasresten aan de bodem. In alle experimenten is veel meer Verticillium tricorpus aanwezig dan Verticillium dahliae. V. dahliae kan al in zeer kleine hoeveelheden gewasschade aanbrengen. De rol van V. tricorpus is onduidelijk. DNA sequencing van een isolaat van V. tricorpus op het betreffende glastuinbouw bedrijf laat zien dat deze soort geclassificeerd kan worden als Verticillium isaacii. Het is noodzakelijk een goed beeld te krijgen van de aanwezige Verticillium soorten en hun pathogeniciteit voordat nieuwe bestrijdingsmethoden van Verticillium verder ontwikkeld worden.

Binnen de biologische glastuinbouw lopen meerdere praktijknetwerken. De paprikatelers werken samen in het netwerk Biodiversiteit onder glas. Naast de zoektocht naar nieuwe bestrijders kijken we vooral hoe natuurlijke bestrijders worden ondersteund door extra bloemen rond en in de kas.
Het praktijknetwerk Compostcomposities zoekt naar mogelijkheden om met compost een effectieve onderdrukking van wortelknob-belaaltjes te bewerkstelligen. In een lopend experiment kijken we naar de overleving van Pseudomonas fluorescens gedurende de compostering.
In Wintergroenten gaan glastuinders op zoek naar verbreding van het assortiment in de winter en vroege voorjaar. Hierbij zoeken we direct naar afzetkansen in verschillende ketens.
In deze Nieuwsbrief houden we u op de hoogte van alle activiteiten en resultaten.

Der Versuch wurde in zwei Häusern 80 Tagen von Beginn der Pflanzung an durchgeführt. An unterschiedlichen Tagen wurde unterschiedlich häufig das Hornkieselpräparat ausgebracht. Um beide Hornkieselbehandlungen zu vergleichen, wurden die geernteten Gurken täglich gezählt, und stichprobenartig ausgewertet. Der Einfluss der Hornkieselanwendung zeigte sich an der der Erntemenge und der Pflanzenfarbe. Pflanzen, die 4 Mal gekieselt wurden, hatten eine dunklere grüne Farbe im Vergleich zu denen, die 8 Mal gekieselt wurden und sahen gesünder aus. Kieselanwendungen direkt nach der Pflanzung erbrachten eine höhere Erntemenge.

At the end of 2015, there were 3 635 organic farms in Latvia, which was 158 more than in the previous year, and the number of certified organic farms was steady over the last six years. The organically certified area was 237 462 ha, or approximately 12% of the total UAA in the country, which was 14.38% more than in 2014. After the Paris Summit on Climate Change held at the end of 2015, Latvia joined the initiative “4‰” proposed by France, the purpose of which was to increase the organic matter content of soil and contribute to the absorption of carbon by the soil through agricultural activities being appropriate under the local conditions from the economic, environmental and social aspects. Thus the application of organic farming methods in agricultural production is one of the possibilities to reduce GHG emissions, as the potential of organic farming to absorb carbon in soil and aboveground biomass is higher than that of conventional farming because most of the year fields are covered with green cover. According to a number of researchers, nitrous oxide emissions from organically managed soils are 492 ± 160 kg CO2 eq. ha−1a−1 smaller than from non-organically ones. The difference in emissions from arable land reaches 497 ± 162 kg CO2 eq. ha−1a−1. However, if measured per unit of crop yield, nitrous oxide emissions are greater by 41 ± 34 kg CO2 eq. ha−1a−1 DM (Skinner et al. 2014). The research aims to characterise the organic farming practices of farms surveyed within the present research, identify the GHG emissions produced by the farms and assess the farms’ contribution to GHG emission mitigation in Latvia.

Organic farming is reliant on alternative active substances like plant extracts for plant protection. Limited stability of plant extracts complicates their use and storage.
Consequently, there is a need for the development of novel formulations like encapsulation that stabilize the active substances, control their release and provide an
appropriate handling. In the project DevelOPAR (Development of a plant avian repellent) we illustrate how a repellent plant extract is formulated in order to be applied
as seed-coating protecting seeds not to be eaten by birds. Testing the methods of ionic gelation and complex coacervation we managed to encapsulate the plant extract
and produce homogenous particles that can be applied on corn seeds using a spin coating process.

Die Nachfrage nach frischem vielfältigem und regionalem Gemüse steigt. Der Großteil des Gemüses wird im Winter entweder importiert oder in geheizten Gewächshäusern angebaut und ist durch einen hohen Energieverbrauch charakterisiert. Im Versuchszentrum Gartenbau der Landwirtschaftskammer NRW in Köln Auweiler wurde zur Erweiterung der Angebotspalette eine Salatmischung aus kältetoleranten Arten untersucht. Die Mischung umfasste Asia-Salate (z. B. Blattsenf, Mizuna, Pak-choi), Sauerampfer, Hirschhornwegerich, Endivie und Speisechrysantheme.
Der Anbau im Versuch und in Praxisbetrieben und erwies sich in drei Jahren als unproblematisch. Die Mischung wurde sowohl optisch als auch geschmacklich sehr gut von den Verbrauchern angenommen. Besonders für direkt vermarktende Betriebe ist der Anbau zur Kundenbindung durch die Erzeugung eines nachhaltigen regionalen Produkts im Winter interessant. Die Erträge lagen bei durchschnittlich 400 bis 500 g/m² je Schnitt. Es wurden je Satz zwei bis vier Schnitte erzielt. Die Ernte erfolgte zwischen Oktober und April.
Im Sommer wurden in den Versuchsjahren 2015 und 2016 verschiedene Kulturverfahren von Slicer-Gurken (Land-Gurken) untersucht. Die Anbauverfahren Bodenkultur und Aufleitung wurden sowohl im Folientunnel als auch im Freiland geprüft. Neben dem Ertrag wurde auch der Arbeitsaufwand für Kulturarbeiten und Erntearbeiten festgehalten. Anhand dieser Kenngrößen wurde der Deckungsbeitrag der verschiedenen Varianten errechnet. Das Ertragspotential der Slicer-Gurken ist im geschützten Anbau bei Aufleitung deutlich höher als bei Bodenkultur.
Zudem kann bei der Ernte eine angenehmere Arbeitshaltung im Vergleich zur Ernte auf dem Boden eingenommen werden. Ein weiterer Vorteil ist die glattere und einheitlicher ausgefärbte Schale der Gurken. Je nach Witterung ist im Freiland die Aufleitung oder die Bodenkultur von Vorteil. Aufgrund dieser Unsicherheit lässt sich der Mehraufwand für die aufgeleitete Kultur im Freiland nicht rechtfertigen. Werden Gurken im Freiland trotzdem aufgeleitet müssen sie vor Wind geschützt werden.
Im Mittel wurde für die Slicer-Gurken (im Tunnel, aufgeleitet) ein Deckungsbeitrag von 7,70 € m² und für die Salatmischung von 10,28 € m² berechnet. Die Erzeugung von Slicer-Gurken im Sommer und einer vielfältigen Salatmischung vom Herbst bis ins Frühjahr ist ein rentables Konzept zur ganzjährigen Nutzung des Folientunnels.

Greenhouses and coverings
Økologisk dyrking av tomat foregår i Norge enten i bakken eller i sekker uten noen form for tilleggslys. I dag er arealet av økologisk tomat ca 6,5 daa. For å oppnå god økonomi er det en forutsetning å ta ut en avling som betaler innsatsen i form av arbeid og energi. Økologisk tomatproduksjon er på mange områder ganske lik konvensjonell produksjon.

Dyrkingsveiledning økologisk agurk i veksthus
Nilsen, Silje Stenstad
Vegetables
Greenhouses and coverings
Dyrking av økologisk agurk med nedfiringsmetoden har foregått siden 2007 i Norge. I storskala økologisk dyrking er det eneste metode i dag. I Norge dyrkes det økologisk agurk på 3 daa. Kulturen må styres klimatisk optimalt hele året og må være mest mulig fri for sykdommer og skadedyr. Det må tilføres CO2 i tilstrekkelige mengder, og lysnivået må holdes oppe. Gjødsel og dyrkningsmedium skiller økologisk veksthusproduksjon av agurk fra konvensjonell produksjon.

Evaluation of inputs
This report describes studies and experiments conducted to replace peat in growing media for certified organic growers. Peat in growing media is one contentious input which has been extensively studied in Organic-PLUS, under the lead of Rafaela Caceres (IRTA) who coordinated Task 5.5, “Examination of promising alternatives, peat”. While some of the studies referred to here have already been described in other publications, some studies are primarily described in the present report. Hence, the level of detail described here varies between the studies. The studies were conducted in countries with greatly different climatic conditions. They range from raising of olive saplings (cuttings) in Turkey (MFAL), various crops in Catalonia (IRTA, EAM), production of extruded fibre from many different plant materials in Germany (ATB), tests to reduce the need for vermiculite in growing media from composted woodchips in UK (CU) and composted horse manure with leaves from hardwood trees for vegetable transplants in Norway (NORSØK). This report includes the main results of the activity done during the project.

A transplant can be defined as a seedling or sprouted vegetative propagation material grown in a substrate or in the field, for transfer to the final cropping site. Nurseries use a range of growing media in the production of transplants, and the quality of a substrate may be defined in terms of its feasibility for the intended use and also according to the climatic condition of the production site. Peat is the worldwide standard substrate, but because of its origin and the increasing environmental and ecological concerns, new alternatives have been proposed for organic production. Here, we reviewed these new alternatives, assuming that the proposed growing media will need to respond in a proper way to specific plant requirements while also taking them into consideration to be environmental friendly, at the same time. Appropriate composting management combined with suitable feedstock material can produce substrates with adequate properties to develop transplants. Potential added-value benefits of particularized compost have been highlighted, and these include suppressiveness or capacity for plant pathogen control, biofertilization, and biostimulation. This added value is an important point in relation to the framework of organic agriculture because the use of chemical fertilizers and pesticides is limited. Different permitted fertilizers are proposed by incorporating them by dress fertilization before planting or by foliar fertilization or fertigation during the seedling production phase. In this context, specific beneficial microorganism inoculation demonstrates better and quicker nutrient solubilization. Its inclusion during seedling production not only facilitates plant growth during the germination and seedling stages but also could bring efficient microorganisms or beneficial microorganisms to the field with the transplants. This review will help to bridge the gap between the producers of compost and the seedling plant producers by providing updated literature.

Evaluation of inputs
The use of contentious inputs linked to plant protection, and the use of peat, plastic and fertilisers used in growing have been mapped in selected organically produced crops in 10 countries across Europe. This report refers the output of this mapping. It shows that organic production has not come very far to phase out peat or plastic. The consumption of these materials seems to be quite comparable to non-organic production systems.The main utilisation of peat is for production of young plants (transplants). Most organic growers purchase plants e.g. for citrus, olives and grafted tomatoes and the growing media has usually a high content of peat. Vegetable transplants are also commonly produced by special growers. Peat is also used for casing layers for organic mushrooms, and as a potting media for aromatic plants.
For plastic, the use is extensive for mulching and to protect crops against frost, less often for insect protection. The use of plastic materials to attach young plants to sticks etc., and to protect grafting wounds in young trees, was also observed. While not big in volume, this use may contribute to micro-plastic waste. Plastic is also very common for solarisation and for tunnels and greenhouses, especially in southern countries. In northern countries,greenhouses are usually made of other materials than plastic. Further research within the Organic PLUS project will reveal farmers and growers who have worked with promising alternatives and develop these further.
For applied fertilisers, which in our context need to be approved for use in certified organic production, the application of commercial products seems to be higher in some countries, e.g. Greece, whereas other countries seem to use much less. This may be explained by economic conditions of the growers, cultural differences, by the extent of organic production and development of a market for such products, by the availability of national fertiliser Companies and by other factors. Information about raw materials used to produce these fertilisers is commonly not readily available but may sometimes be found under information about the company’s history. These website sections also reveal that fusions of fertiliser Companies occur rapidly.
Many fertiliser products seem to be derived from residuals from sugar or starch production. Horn grid, meat and bone meal, blood meal and feather meals are well known organic fertilisers but were not so much observed in this study. Instead, we observed that animal hides are an important raw material for organic N fertilisers. Seaweed products are quite common, whereas fish-based products were only mentioned from UK. Non-organic manure (from conventional farms) is used in all countries, commonly as pelletised dry poultry manure.
