Avoiding hoeing in organic oilseed rape

Author: Hansueli Dierauer

Problem: 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.

Solution: Undersowing helps to increase soil cover in autumn and thus suppress the emergence and growth of weeds. In oilseed rape, frost-sensitive legumes are best suited for undersowing. They fix nitrogen and thus contribute to the large nitrogen requirement of oilseed rape plant through mineralisation. After dieback in winter they form a thin layer of mulch on the field
