Assessment of relative nitrate losses from Organic and Convetional farming systems, based on recent measurements Organic Eprints
The objective of this preliminary study is to assess the relative nitrate losses to be expected from organic and conventional farming systems. The study will compare recent measurements made on organic farms (MAFF contract NT1313) with those made on conventional farms within Nitrate Sensitive Areas and, where possible, eleswhere. The report will aim to identify the points in the rotation where differences occur, and to discuss these in the light of the whole farming system. The comparison is relevant to MAFF's nitrate and environmental policy, since if organic farming reduces nitrate losses significantly compared to conventional farming, on an area basis, it would be worth considering as an option within Nitrate Sensitive Areas or Nitrate Vulnerable...

Use of green manure, catch crops, and deep rooted crops for nutrient management in an organic vegetable crop rotation Organic Eprints
Thorup-Kristensen, K..
The results and conclusions from an unfertilized organic vegetable rotation are presented. It is discussed how catch crops, green manure crops and deep rooted crops have all been important tools in maintaining the fertility during the 9-year rotation experiment. The results indicate that these methods have helped to direct the available nitrogen towards crop use, by concentrating available nitrogen in upper soil layers and making nitrogen mainly available in the spring rather than in the autumn. Soil measurements indicate that soil N fertility has been increasing during the 9 years.
