Farm Practices That Improve Soil Health: Crop Rotations and No-Till

Implementing crop rotations and no-till practices are common suggestions to reduce erosion, control pests, and improve yields. These practices can also improve soil health through an increase in soil carbon levels.

Economics of Different Crop Rotation Systems in South Dakota

Economic returns are an important factor to consider when selecting crop rotation systems.

Crop Rotation Potential: Improving Soil Health & Farm Profitability

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 Crop Usage in South Dakota is on the Rise

The number of South Dakota producers who use cover crops has been increasing at an accelerating rate over the past ten years.

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 variety, 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.
