Proper sampling of manure, knowing the rate of application, and uniform application are important to efficient manure use.
With Nebraska being one of the nation's top livestock producers, the state has a lot of manure that can serve as a valuable resource for crop production.
Benefits of manure include the nutrients supplied, especially the nitrogen and phosphorus needed for most Nebraska soils, and its soil amendment effects. The soil amendment effects often result in increased productivity for several years after application.
Typical yield increases in the first year after application are 7 bu./acre of corn and 2 bu./acre of soybean, but the effect is commonly greater on sandy soil, once-eroded sites, and heavy clay soils.
