Soil degradation has become one of the most pressing global issues, because of its adverse effects on world food security, environment and quality of life.
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.

There seems to be a misconception nowadays in much of the public that in order for agriculture to be sustainable in the future, there is a need to go organic. Organic agriculture can be sustainable, but so can traditional agriculture.
Cover crops have been gaining a reemerging acceptance over the last decade, with very few producers disagreeing about the potential soil health benefits of adding cover crops to their farming operation.
