Summary

The projected expansion of organic farming in Denmark is conditioned on increased arable crop production, which requires higher and more stable crop yields. This must be achieved while also phasing out the use of imported conventional manure and reducing environmental impacts, such as greenhouse gas (GHG) emissions. HighCrop has two main hypotheses: 1) Higher yields and reduced environmental impact can be achieved by introduction of energy crops and improved management of nitrogen (N) in catch crops, green manure and crop residues; and 2) Low yields in practical arable organic farming are caused by a knowledge gap that requires new strategic management tools to overcome. HighCrop applies a comprehensive approach linking research, development and demonstration. Research will improve our understanding of effects of N dynamics and weed pressure on crop productivity, N leaching, GHG emissions and soil biodiversity to derive essential models for N and weed management in organic arable cropping systems. The key to development and dissemination will be new knowledge transfer tools which will be targeted by identification of real and perceived barriers on the farm, as well as in supply and knowledge chains. These concepts and tools will be tested on organic farms and disseminated to Danish organic advisers and farmers. HighCrop will also make use of participatory approaches to synthesize and disseminate knowledge by organising workshops focusing on different supply chains.

Summary translation

Den forventede udvidelse af det økologisk dyrkede areal i Danmark er betinget af øget planteproduktion, som kræver højere og mere stabile udbytter. Denne udfordring skal kunne løses samtidig med at importen af konventionel husdyrgødning udfases og miljøpåvirkningen, f.eks. udledningen af drivhusgasser, reduceres væsentligt. HighCrop har to hoved-hypoteser: 1) Højere udbytter og mindre miljøpåvirkning kan opnås ved at inddrage flerårige energiafgrøder og forbedre styring af kvælstof (N) frigivet fra efterafgrøder, grøngødninger og afgrøderester; og 2) Lave udbytter i praktisk økologisk jordbrug skyldes et vidensgab mellem forskning og praksis, som kræver nye strategiske planlægningsværktøjer for at løse. HighCrop bygger på et tæt samarbejde mellem forskning, udvikling og formidling. Forskningen vil øge kendskabet til effekter af N-dynamik og ukrudtstryk på afgrødeproduktivitet, N-udvaskning, drivhusgasemissioner og biodiversitet. Udvikling og formidling vil bygge på nye koncepter for beslutningsstøtte og vidensformidling baseret på en detaljeret analyse af barrierer på bedriften samt i produkt- og videnskæderne. De nye koncepter og værktøjer vil blive testet på økologiske bedrifter og formidlet til danske økologiske rådgivere og landmænd. HighCrop vil også analysere og syntetisere viden gennem afholdelse af en serie workshops med fokus på forskellige værdikæder.
