Definition:
A cover crop is a type of plant grown to suppress weeds, help build and improve soil, and control diseases and pests. Cover crops are also called "green manure" and "living mulches."
They're called "green manure" because they provide nutrients to the soil much like manure does. And as "living mulches," cover crops prevent soil erosion.
Once grown, cover crops are usually mowed and then tilled into the soil.
Also Known As: living mulch, green manure
Examples:
Rye is a plant commonly used as a cover crop.
