Summary in the original language of the document

The dossier summarises the results of 45 years of long-term research in a concise and comprehensible manner. It is aimed at interested experts from practice, advisory services and science. The DOK trial compares biodynamic, organic and conventional farming systems. The dossier presents results from the areas of yield, soil quality, nutrient supply, biodiversity and climate.

Summary translation

In dem Dossier werden die Ergebnisse aus 45- Jahren Forschung im Langzeitversuch kurz und verständlich zusammengefasst. Es richtet sich an interessierte Fachleute aus der Praxis, Beratung und Wissenschaft. Im DOK-Versuch werden die landwirtschaftlichen Anbausysteme Biologisch-dynamisch, Biologisch-organisch und Konventionell miteinander verglichen. Das Dossier stellt Ergebnisse aus den Bereichen Ertrag, Bodenqualität, Nährstoffversorgung, Biodiversität und Klima vor.

EPrint Type:	Practice tool
Teaser:	A 45-year comparative study of organic and conventional cropping systems.
What problem does the tool address?:	Rarely have scientific experiments been designed to last as long as the DOK trial. This continuity is particularly valuable for investigating many research questions, as the relevance of some results only becomes apparent after a long time period. This also applies, for example, to long-term observations of the effects of climate change. Short-term results are relevant, but they cannot capture the long-term ef- fects of external influences that unfold over time. From the very first year of the DOK trial, various external influences presented themselves due to the methods chosen for conducting the experiment, and the questions that researchers proposed – depending on the objects of investigation and the social issues at the time – have evolved over the years and decades.
What solution does the tool offer?:	2 The DOK Trial \| 2024 \| FiBL The DOK trial has investigated the differences between organically and conventionally farmed arable crops since 1978. This report summarises the most important findings from more than 40 years of research for interested agriculture experts, consultants and researchers in a concise and comprehensive way. The DOK trial compares biodynamic (BIODYN), bio-organic (BIOORG) and conventional (CONFYM) agricultural systems. The trial thus simulates farms that conduct arable and livestock farming. The exclusively mineral-fertilised, conventional CONMIN system represents a livestock-free cropping system. In each of the BIODYN, BIOORG and CONFYM systems, two fertiliser intensities are examined.
