Status Quo Analyse von Dauerversuchen zum Ökologischer Pflanzenbau

Summary in the original language of the document

The research project focused on a status-quo analysis of long-term field experiments for organic farming in Germany, Austria and the German speaking part of Switzerland. The study comprised long-term field experiments with an expected minimum duration of five years. The status-quo analysis categorized the long-term field experiments into four main research fields: a) system comparison, b) production engineering, c) fertilisation and d) soil fertility and further key aspects.
All in all, 47 long-term field experiments were identified. The four main research fields chosen were investigated in 20, 24, 27 and 46 long-term field experiments, respectively. The system comparison of the main research fields identified the major research into “conventional versus organic farming” and “organic farming: ‘stocking ratio’ versus stockless” with eight resp. twelve experiments. In production engineering research focused on “soil cultivation” with 14 experiments. Soil fertility and further key aspects, yield and humus formation/humus balance were investigated in 40 resp. 35 field experiments.
