Using cover crops can be beneficial not only for soil health but also for the environment. However, relatively few farmers have adopted cover crops, so understanding the barriers to adoption is necessary. We used a probit model with data on 1,712 soybean producers from the 2012 USDA Agricultural Resource Management Survey to identify factors affecting adoption of cover crops. We found that more precipitation was positively correlated with adoption, as was more hired labor. Adoption was also positively correlated with crop diversification and no-till adoption, which may relate to equipment availability.
