Sustainability of winter oilseed rape cropping systems in NW Germany
The assessment of oilseed rape cropping systems according to the principles of sustainable farming requires a comprehensive approach taking into account environmental, economic and social aspects of production. We used the REPRO model to assess different farms in the northern part of Germany.Compared with average figures in the region, the farms included in the project showed a moderate use of pesticides and only little improvement seems possible at the moment. Gtiven the rotations of mainly winter oilseed rape (Brassica napus), winter wheat (Triticum aestivum) and winter barley (Hordeum vulgare), the balance for organic substance on the farm and on the field level are stable. From an energetic point of view, the farms had an above average performance. The major critical point from an environmental point of view has been the nitrogen balance, however, differences between the farms showed the range for possible improvements.
