BROOKINGS, SD – Cover crops can improve soil health and drought resilience, but South Dakota State University Extension says economics remain a major adoption hurdle. 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% 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.
Farm-Level Takeaway: Grazing and cost-share assistance can help cover crops reach a positive return sooner while producers build longer-term soil benefits.
