Looking for ways to reduce fertilizer expenses without cutting yield? A thorough understanding of nutrient management can help you more efficiently manage your fertilizer program and improve the bottom line. With that in mind, a fertilizer management publication targeted specifically for Nebraska is now available.
The 176-page UNL Extension Nutrient Management for Agronomic Crops in Nebraska (EC 155) is designed to provide in-depth information on Nebraskaâ€™s crops, soils and major nutrient management issues. It provides nutrient recommendations for all of Nebraskaâ€™s major agronomic crops in a single resource.
The manual is divided into two major sections. The first section focuses on basic principles of soil fertility for the primary, secondary and micro nutrients, as well as chemical and physical properties of soil and soil management. Typical divisions within a chapter include nutrient availability, forms and sources of the nutrient, deficiency symptoms, crop sensitivities and recommendations. Chapters include: Nitrogen (view this chapter on-line), phosphorus, calcium and magnesium, sulfur, micronutrients, pH and liming, manure and organic residual management, and soil testing and nutrient recommendations.
The second section devotes a chapter to nutrient management for each of the stateâ€™s major agronomic crops, with information on current fertilizer recommendations for each. Chapters include: Corn (view this chapter on-line), winter wheat, grain and silage sorghum, oats and spring grains, alfalfa, dry edible beans, soybeans, sugar beets, sunflowers, millet, grass pastures and hayland, popcorn and potatoes.
Written by soil fertility faculty in UNL Department of Agronomy and Horticulture, it is intended for producers, crop consultants, and fertilizer dealers. It contains color photographs, illustrations and 90 tables.
The Nitrogen Chapter available online is from Section I, which is organized by nutrient, and the Corn Chapter is from Section II, which is organized by crop.
The cost of the publication is $12. To obtain copy of Extension Circular EC155, contact your local Extension office or the UNL Extension Publications Warehouse, Box 830918, Lincoln, NE 68583-0918 or call (402) 472-9712.
