http://orgprints.org/4582/ Common Couch-grass control with less tillage Control of Common Couch-grass often conflicts with the need to retain nutrients in organic cropping systems, as it involves intensive tillage in the post-harvest period. Thus, preferably the soil should be cropped through the entire year to prevent nutrient leaching from the root zone. Research has shown that new control strategies may combine the reduction of couch infestations and a soil cover with plants during the post-harvest period. This may have potential for practical implementation.
