Making the Most of Your Nitrogen and Your Dollar

Learn new strategies for applying nitrogen that optimize plant growth while minimizing nutrient movement to surface and ground water. Peter Scharf, University of Missouri professor in plant sciences, will demonstrate the latest technology in crop sensors to evaluate corn nitrogen status in fields throughout the year to help producers make the best decisions about nitrogen application practices. He will also discuss best practices to use with crops sensing technology from managing crop height and ground temperature to leaf wetness. Leave this session with all the resources you need to improve your yield and bottom line.

Peter Scharf is a professor in the University of Missouri Division of Plant Sciences and an Extension nutrient management specialist. His program covers all aspects of nutrient management for agronomic crops with a focus on nitrogen management. Specific areas of emphasis include diagnosing optimal nitrogen (N) fertilizer rates for corn, cotton and wheat; advanced technologies including crop reflectance sensors and remote sensing to diagnose optimal N fertilizer rates; and on-farm demonstrations of real-time variable-rate N fertilizer applications using crop reflectance sensors. Other areas include diagnosis of N loss and need for rescue N using remote sensing; evaluation of N loss risk as a function of source and timing; and quantifying water quality, greenhouse gas mitigation and climate adaptation benefits of advanced N management approaches. He has conducted a great deal of his research on working farms with over 400 on-farm experiments and demonstrations. Soil erosion, soil carbon, cover crops and tillage are areas that he has recently added to his program. He is currently chair-elect of the Soil Fertility and Plant Nutrition Division of the Soil Science Society of America.
