Summary

The most organic produced potatoes are used for direct marketing or home requirements. But due to the growing demand for “Convenience-products” like potato crisps and chips the production of processing potatoes offers farmers an alternative. In contrast to conventional agriculture the nutrient supply in organic potato production must be secured by preceding crops or organic fertilization. Clover grass as preceding crop is common in praxis. But as the case may be how the clover grass is utilized (mulching, cut mowing) a different nitrogen fixation and mineralization is possible. In a period of two years (2003/2004) the effect of different clover grass management systems on yield, grading and quality of processing potatoes was under examination on the experimental farm of the University of Kiel in Northern Germany. The tested management systems showed only a low effect on yield and quality on the following crop potato. In 2003 a small yield increase was achieved by the mulch system.
