The Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat, and Alfalfa has served as a cornerstone in nutrient management in field crops for Indiana, Michigan, and Ohio. As crop production practices in this region evolved, many questioned if the nutrient management guidelines were still relevant today.
From 2014 - 2018, we coordinated hundreds of on-farm strip trials across Ohio in corn, soybeans and wheat, evaluating crop response to N, P, K, and S. It was a tremendous collective effort with the ultimate goal of providing farmers objective information to manage nutrients as judiciously and profitably as possible.
The Tri-State Fertilizer Recommendations are now published and available!
