No more hoeing in organic oilseed rape

Dierauer, Hansueli

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 solution would be to undersow frost sensitive legumes. These are the benefits:

  • Suppression of seed weeds
  • Reduction of soil erosion
  • Reduction of nutrient leaching
  • Nitrogen is fixed and utilised by the oilseed rape.
  • Weed control is usually not required, which helps to reduce variable costs.
  • Carbon is stored and released less from soil
