Researchers with the South Dakota Agricultural Experiment Station at SDSU are working with SDSU Extension, faculty and staff on a study to help determine the long-term economic benefits of conservation practices, such as no-till, cover crops and diverse crop rotation, to South Dakota's agriculture producers and citizens in general.
Two-year corn-soybean rotation coupled with heavy chemical inputs has become the routine practice of agricultural production in the Midwestern United States. According to USDA/NASS data, corn and soybean prices received by producers in South Dakota both reached the peak levels of $7.39 and $16.00 per bushel, respectively, in August, 2012.
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.
