Using cover crops is beneficial not only for soil health but also for the environment, but many farmers have not adopted cover crops. We used a probit model with data on 1708 soybean producers from the 2012 USDA Agricultural Resource Management Survey to identify factors affecting adoption of cover crops. We found that perceptions of yield benefits were positively correlated with adoption, while concern about weeds was negatively correlated. Adoption varied by region. Educational efforts should focus on farmers’ perceptions and concerns about using cover crops, such as timing of seeding cover crops, especially for farmers in colder regions.
