Cover crops have to produce a certain amount of growth, or biomass, in order to effectively reduce erosion and soil nutrient loss, suppress weeds, and supply forage. Several studies have indicated a threshold or minimum biomass (dry matter) of 1,000 lb/ac, which is similar to 6 to 8 inches of above-ground growth, although more biomass will likely lead to better outcomes.
