Hairy vetch is commonly grown as a cover crop in most areas of the United States due to its useful traits that include winter hardiness, its survivability in wetter soil, and ability to provide nitrogen to subsequent crops through biological nitrogen fixation in the soil (Clark, 2007; Wilke and Snapp, 2008).
