What are Cover Crops?
Cover crops are grasses, legumes, and other forbs that are planted for the protection and enrichment of the soil. Cover crops are traditionally planted on farms but can be used in gardens. A cover crop is any crop grown to cover the soil and may be incorporated into the soil later for enrichment.

What types of cover crops should I use?
There are many varieties of cover crops and selection depends on when the species can be planted and what is the goal for its use. Legume species fix atmospheric nitrogen into a form that plants and microorganisms can use. Non-legume species recycle existing soil nitrogen and other nutrients and can reduce leaching losses. A combination of two or more types of cover crops might be beneficial for establishment and improved nutrient utilization. Visit OSU's summary of NRCS's 340 standard for more information.
