A cover crop is a crop planted primarily to manage soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem (Lu et al. 2000), an ecological system managed and largely shaped by humans across a range of intensities to produce food, feed, or fiber.
Cover crops are of interest in sustainable agriculture as many of them improve the sustainability of agroecosystem attributes and may also indirectly improve qualities of neighboring natural ecosystems. Farmers choose to grow and manage specific cover crop types based on their own needs and goals, influenced by the biological, environmental, social, cultural, and economic factors of the food system within which farmers operate (Snapp et al. 2005).

Famous quotes containing the words crop and/or cover:
“And, by the way, who estimates the value of the crop which nature yields in the still wilder fields unimproved by man? The crop of English hay is carefully weighed, the moisture calculated, the silicates and the potash; but in all dells and pond-holes in the woods and pastures and swamps grows a rich and various crop only unreaped by man.”
—Henry David Thoreau (18171862)
“You may call a jay a bird. Well, so he is, in a measurebecause hes got feathers on him, and dont belong to no church, perhaps; but otherwise he is just as much a human as you be. And Ill tell you for why. A jays gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasnt got any more principle than a Congressman.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
