Ecological effects of cover crops

Abstract

Abstract: This paper reviewed the effects of cover crops in reducing soil loss,surface runoff,NO₃^- leaching and water pollution,and elucidated roles of cover crops in controllling pest insects, weeds and diseases, and increasing soil nu trients. The potential roles and appropriate application of cover crops in sustainable development of agriculture were also discussed.

Key words: Cover crops, Soil erosion, Nutrient cycling, Insect and disease control, eco-geographical region, Daxing’an Mountains, GIMMS NDVI 3g, vegetation phenology
