Cover crop information in this section is organized by cover crop type. Broadleaf cover crops are non-grass, non-legume species such as buckwheat. Legume (nitrogen fixing) cover crop species include alfalfa, clovers, and vetches. Grass species include rye, millets, and sorghum-sudangrass. The use of cover crop mixes can increase the range of benefits provided by cover crops. Information on general cover crop management (such as planting and termination methods) is also posted.
