Cover crops are used in rotation with cropping systems to improve soil quality and to suppress pests. Use of cover crops prior to replanting on sites with grape may provide a sustainable alternative to chemical pesticides and may maintain or improve soil quality. The objectives of this study were to investigate how cover crops affect weed and nematode populations and soil physical and chemical properties when used on replant sites with Vitis spp. (grape).
