Cover Crops in Sustainable Food Production
Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...
متن کاملInfluence of Cover Crops on Populations of Soil Nematodes
Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92.

متن کاملCover crops and control of arthropod pests of agriculture
Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...
متن کاملAllelopathic Weed Suppression Through the Use of Cover Crops
There has long been observed an inhibitive response by plant species to certain neighboring plants. The Greek philosopher and botanist, Theophrastus, noted this effect from cabbage as early as 300 BC (Willis 1985). Since that time, others have documented similar plant interactions. In 1937, Austrian botanist, Hans Molisch, described this phenomenon as allelopathy, which he determined to be the ...
