Cover cropping provides a host of benefits that with years of repeated practice can pay off with high crop yields, reduced input costs and healthier ecosystems. Cover crops are grown not for short-term economic gain but for the benefits they provide for the subsequent main crops. Cover crops create biomass that protects bare soils against runoff and erosion, smothers weeds, helps control diseases and improves soil fertility. Thus, the benefits from cover crops rely heavily on biomass.
