The NRCS’s National Soil Health and Sustainability Team and Plant Materials Program are working together to improve our knowledge of using cover crop mixes to produce healthy soils.
Cover crops have the potential to provide multiple benefits in a cropping system. They prevent erosion, improve soil’s physical and biological properties, supply nutrients, suppress weeds, improve the availability of soil water, and break pest cycles along with various other benefits. The species of cover crop selected along with its management determine the benefits and returns.
Cover Crop Termination Guidelines
The termination guidelines provides information on termination of cover crops on non-irrigated cropland. They were created by NRCS, Risk Management Agency (RMA), Farm Service Agency (FSA), and other public and private stakeholders to address concerns about cover crops’ impact on crop insurance.

The following plant guides describe the characteristics of some commonly used cover crops. They provide assistance in selecting appropriate cover crops, when and how to plant and when to terminate or incorporate the plant into the soil.
Plant Guide for Crimson Clover (Trifolium incarnatum) (PDF; 326 KB) Crimson clover is commonly used as a winter or summer annual cover crop in rotation with vegetables or field crops (Clark, 2007). It can be used alone or as part of a mixture with other legumes, small grains, and winter annual grasses.
Plant Guide for Field Mustard (Brassica rapa ssp. rapa) (PDF; 299 KB) Field mustard (Brassica rapa ssp. rapa) is an annual or biennial forb that is used as forage, cover crop, or biofumigant. There are also horticultural cultivars used as vegetable crops including turnip and rapini or broccoli raab.
