The Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat, and Alfalfa (Extension Bulletin E-2567) was first published in 1995 and has served as a cornerstone in nutrient management in field crops for Indiana, Michigan, and Ohio. Field crop production practices in this region have changed over the past two and a half decades, and water and air quality issues in this region also underscore the need to manage nutrients as judiciously and profitably as possible. This publication represents a tremendous collective effort by many committed agricultural professionals with the ultimate goal of providing objective and scientifically vetted nutrient management information to farmers in this region.
The work was made possible through the committed financial support of the Ohio Soybean Council, Ohio Corn and Wheat, and the USDA National Institute for Food and Agriculture, the Corn Marketing Program of Michigan, the Michigan Wheat Program, Michigan State University Project GREEEN, Michigan AgBioResearch, the Michigan State University’s College of Agriculture and Natural Resources, and the School of Environment and Natural Resources at The Ohio State University.
