Cover Crop Adoption: Farmers’ perceived benefits & barriers
Cover crops are generally defined as crops planted between cash crops to cover and protect the soil. Some demonstrated benefits of cover crops include: reduced soil erosion, increased soil organic matter, increased biological diversity, increased nitrogen supply, and weed control. Depending on the farmers’ objectives, different species of cover crops can be planted. For example, if a farmer’s main objective is to increase nitrogen supply, then legume cover crops best suited to the farm area should be selected.
