This document summarizes information collected from more than 1,200 farmers across the United States who completed an online survey on cover crops in early 2015. A large majority of respondents (84%) planted cover crops; 16% have not. The report sheds light on farmers’ motivations for planting cover crops, their expectations of the benefits of the practice, users’ concerns about cover crops and barriers to adoption among non-users. For the third year in a row, this survey charted a statistically significant increase in corn and soybean yields following cover crops. Corn yields rose 3.7 bushels per acre, or 2.1%, following cover crops, while soybean yields increased a mean of 2.2 bushels per acre, or 4.2%.
