Cover crops have many environmental benefits. For example, cover crops can significantly reduce nitrate and phosphorus leaching from agricultural fields by scavenging residual nutrients, storing them in the soil, and making them available for future crops. Moreover, cover crops provide significant soil health benefits, including building organic matter over time and reducing erosion of topsoil. Cover crops have potential to remove carbon dioxide from the atmosphere and store it as soil carbon, building high quality soil organic matter over time (Lal et al. 1998). Yet, farmers often do not receive enough benefits to warrant planting cover crops, particularly when they have no prior experience with managing cover crops. Therefore, public policies supporting cover crop use may be justified given their public benefit. Herein, we will discuss methods to provide public support for cover crops, including direct subsidies for planting cover crops and providing insurance benefits for cover crops. Overall, direct subsidies likely are the most efficient ways of providing support and may only need to be temporary as individuals gain experience with cover crops.
