The Department of Agriculture National Resources Conservation Service awarded a $630,861 Project Grant to the Division of Agriculture of the University of Arkansas to improve the accuracy and transparency of soil-test fertilizer recommendations. The project will update decades-old phosphorus and potassium recommendations and develop an unbiased decision-support tool for nutrient management, which will be available for use by anyone involved in this area. This grant is funded through the Environmental Quality Incentives Program (CFDA 10.912), which promotes agricultural production, forest management, and environmental quality as compatible national goals. The project will be completed by July 31, 2026.
