Última Rohphosphatmobilisierung von Sommerweizen, Weißlupine und Ackerbohne in einer Fruchtfolge Organic Eprints Steffens, Prof. Dr. Diedrich; Stamm, Roland; Yan, PD Dr. Feng; Leithold, Prof. Dr. Guenter; Schubert, Prof. Dr. Sven. In organic farming rock phosphate is used as a mineral P fertilizer, although the agronomic efficiency is limted. The objective of this study was to investigate in field and pot experiments the mobilization of rock phosphate by P-efficient plants (white lupin and faba bean) and the P availability for P-inefficient plants (spinach and maize) during a crop rotation in 2002/2003 and 2003/2004. The P uptake of spinach was higher in a crop rotation with white lupin and faba bean than in a crop rotation with summer wheat. In pot experiments the application of new basic slag phosphate (CaHPO4) resulted to a higher P uptake of the plants than rock phosphate.

The cropping of rape seed is rather uncommon in organic farming. Still, rape seed cropping can contribute to efficient nutrient utilization (especially of nitrogen) in a crop rotation. This paper presents results on nitrogen dynamics after perennial clover grass as affected by rape seed cropping compared to winter wheat. It could be shown, that Nmin amounts in the soil are lowered by rape seed compared to winter wheat.
