A winter cover crop can benefit the soil and/or subsequent crop, but cover crops are not harvested for feed or sold as a commodity. Cover crop benefits include soil erosion protection, increased soil organic C accumulation, weed suppression, and soil moisture conservation. Coarse-textured, degraded soil found throughout the Southeast can be very receptive to these benefits. In general, benefits improve as surface biomass increases, and surface biomass persistence is extended. Persistence is key because hot, humid conditions in the summer speed up surface biomass decomposition. Read more.
