Oilseed rape sown in summer only forms a dense canopy in the following spring. In autumn and winter, the stands can become infested with weeds, and in vulnerable areas, soil erosion can occur. The new DiverIMPACTS practice abstract deals with undersowing, which helps to increase soil cover. In oilseed rape, frost-sensitive legumes are best suited for undersowing: They fix some nitrogen and thus contribute to the large nitrogen requirement of oilseed rape plant through mineralization. After dieback they form a layer of mulch on the field.
