| In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower. |

| Consumers have become more aware of healthy and safe food produced with low environmental impact. Organic agriculture is of particular interest in this respect, as manifested by 5.768 million hectares managed pursuant to Council Regulation (EEC) 2092/91 in Europe. However, there can be a considerable risk that the avoidance of chemical inputs in organic farming will result in poor food quality. Here the results of a study on the quality of wheat (Triticum aestivum L.) grown in a 21 year agrosystem comparison between organic and conventional farming in central Europe are reported. Wheat was grown in a ley (grass/clover) rotation. The 71% lower addition of plant-available nitrogen and the reduced input of other means of production to the organic field plots... |
