Summary

The effect of different management strategies on growth, composition and nutrient up¬take of a cover crop mixture of summer vetch and oil radish were tested in field ex¬pe¬ri¬ments on the Research Station Gladbacherhof. Slurry application and cereal straw management (incorporation vs. harvesting) affected composition of cover crop signifi-cantly: slurry application decreased legume content and biological N2-fixation signifi-cantly. By this way the N-input in farm cycle were reduced. The higher the amount of straw residues were left on field, the higher the legume content was in the cover crop mixture. High legume content in cover crop mixtures not only increased N2-fixation, but also P uptake of the cover crop. According to available literature additionally mobilised P increased the P supply of following crops. The harvest of cover crop sprout reduced nitrate leaching potential significantly especially when winter crops were following. The harvest of the cover crops increased the amounts of N cycling within the farming system. Hence it allows higher N manuring to selected crops with a high N demand.
