Animal feeding operations, concentrated animal feeding operations, and confined animal feeding operations are defined by size and management, and have different requirements for nutrient management plans.
Some standard information on nutrient concentrations of manures and effluents from several species will be presented, with some generalizations about nutrient availability in the first and subsequent years.

Dr. Clay Robinson, PhD, CPSS, PG
American Society of Agronomy and Soil Science Society of America
Clay Robinson earned BS and MS degrees from West Texas State University, with a concentration in plant science/agronomy, and a PhD in Soil Management from Iowa State University. He is a Certified Professional Soil Scientist and former professor who taught soil science and agronomy courses at two universities from 1992 to 2011. He is published on the beneficial use of manure as a by-product, and on the capacity of three counties in the Texas High Plains to utilize for crop production all the nitrogen and phosphorus excreted in manure by the approximately 2 million feeder cattle. He supervised graduate students in research addressing the chemical and physical properties of soil and effects on crop yields after long-term applications of manure and effluent. He also worked with a CCA to evaluate field records of several producers of N from soil nitrate tests, stalk nitrate tests, and N fertilizer and manure applications on crop yields.
