cover crop


Also found in: Dictionary, Thesaurus, Wikipedia.

cover crop,

green temporary crop grown to prevent or reduce erosion and to improve the soil by building up its organic content. Green-manure crops, which are specifically grown for their organic content and other feature that enable them to improve the soil, but which may be composted before being incorporated into the soil, are usually classed as cover crops. In orchards a cover crop is sometimes used to check the growth of some fruits when they reach maturity by supplying a plant that will compete with the tree for the nutriment in the soil. Cover crops are often the first means used to rehabilitate land that has become run down as the result of poor farming practices and neglect. Leguminous plants (e.g., clovers, vetches, and soybeans) and nonleguminous (e.g., rye, barley, wheat, and turnips) are used. See also catch cropcatch crop,
any quick-growing crop sown between seasons of regular planting to make use of temporary idleness of the soil or to compensate for the failure of a main crop.
