BROOKINGS, S.D. (RFD News) — Cover crops can improve soil health and drought resilience, but South Dakota State University Extension says economics remain a major barrier to adoption. Establishment costs typically range from $42 to $120 per acre, depending on seed, planting, fertilizer adjustments, and termination.
Research cited by SDSU estimates cover crops can reduce fertilizer costs by about $7.98 per acre and improve subsequent crop returns by $31.37 to $66.42 per acre. Benefits from erosion control, water infiltration, and soil structure may add value over time.
Integrating livestock can improve the near-term economics. South Dakota research found grazing cover crops generated net benefits of $17.23 per acre in the first year and $43.61 per acre in the second year after accounting for establishment and grazing expenses.
Cost-share programs can also reduce financial risk. The Environmental Quality Incentives Program can cover up to 75 percent of establishment costs, while the Conservation Stewardship Program supports producers expanding more advanced systems.
SDSU says adoption remains modest statewide but is growing in several eastern South Dakota counties.
