Profitable corn production requires an adequate soil fertility program. Insufficient nutrients will lower yields; excess nutrients will lower profit margins and may damage the environment through nutrient runoff and leaching. Corn must receive adequate amounts of nutrients to fully realize yield benefits from other management practices such as early planting dates, selection of adapted hybrids, and effective weed and insect control. This publication will help you supply the optimum nutrient level for your fields (11 pages).
