Abstract: Cover crops—which are typically added to a crop rotation in between two commodity or forage crops—provide living, seasonal soil cover with a variety of on-farm benefits, such as increased soil moisture capacity, improved nutrient cycling, and weed suppression. Cover crops can also provide public benefits by reducing sediment loss, nutrient runoff, and leaching; reducing flooding; and storing carbon in the soil. When choosing a cover crop, a farmer might consider a variety of factors, including the cost of the seed, the intended use (e.g., cover only, grazed, or harvested for forage), how the cover crop fits into the cash crop rotation and anticipated planting and harvest dates, and long-term management goals (e.g., to prevent soil erosion or to improve soil organic matter). Soil and climate, as well as the availability of financial assistance, are also important factors. In 2017, approximately one-third of U.S. acres that planted cover crops received a financial incentive payment from either a USDA working lands conservation program or a similar State program.
