This webinar will introduce the CCA to the Performance Objectives for the Nutrient Management Planning Specialist exam. As an example, a scenario-based case study will examine the land base required to utilize the N and P excreted in manure annually based on the herd size. N and P in manure will be estimated using published values and laboratory manure nutrient analysis, and availability due to mineralization. The soil test N and P nutrient requirements based on yield goals will be adjusted for manure N and P credits.

Speaker Bio:
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.
