Patterns of cover crop use, adoption, and impacts among Indiana farmers

Cover crops have recently been generating a lot of interest in agriculture for their agronomic benefits, including erosion control, nutrient restoration, and increased cash crop yield. However, the value of these benefits is not well established and likely highly variable. The factors that influence a farmer’s decision to adopt or not adopt cover crops are also a point of interest to conservationists and policy makers. As part of a long-term study estimating the benefits and costs of cover crops, this study analyzed five years of historic information collected from Indiana farmers, who either grew or did not grow cover crops. No significant impact was found from cover crops on cash crop yields, but several interesting correlations in cover crop use were found. Cover crop use was higher on steeper fields. There was also a high correlation between the use of cover crops and no-till.
