Summary
In a field experiment the potential of mixtures of winter cereals and catch crops to reduce nitrate leaching was investigated. Pure winter wheat showed the highest N-losses (56 kg N ha-1). Compared to a control without a catch crop, winter rye and oilseed radish grown in pure stand or in mixture with a winter cereal reduced nitrate-leaching by 30 to 80 %. However, common vetch had a significant lower potential compared to the tested non-legume catch crops. Further investigations are needed to optimize the system with special regards to the concurrence between cereal and catch crop in autumn and in early spring.
