In-season Nitrogen Management Webinar Series

Nitrogen is often the most limiting nutrient to cereal crop production, and with phosphorus, poses the greatest environmental challenges of all plant essential nutrients. More producers are switching to split-nitrogen and N-season nitrogen applications to limit N losses and limit adverse environmental consequences of N leaching and denitrification. This webinar series will review some of the commercially-available models for in-season N management, and discuss the utility of optical sensors and soil testing to improve N management.

The Nitrogen Cycle and Modeling N Loss

Nutrient management begins with a proper understanding of the nutrient cycle: inputs, losses, transformations, translocations, sinks, and the environmental, chemical and biological factors that affect the cycle. Current tools use weather inputs to model the fate and availability of nitrogen during the growing season. All models are based on certain assumption, and must be calibrated and correlated to local conditions. This webinar will introduce CCAs to the main components to consider in evaluating models as a nitrogen management tool.

Clay Robinson earned BS and MS degrees from West Texas State University, with a concentration in plant science/agronomy, and a PhD in Soils 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 worked for an environmental consulting firm before becoming the Agronomy and Soil Science Education Manager for the American Society of Agronomy and Soil Science Society of America in early 2014. He is now responsible for developing and coordinating continuing education materials for the certification programs. Clay often talked to producer groups about soil and water conservation, irrigation management, and nitrogen and phosphorus management in dryland and irrigated production systems. He also provided an introduction to soils for urban gardeners every year, and talked with more than 20,000 middle school children about the importance of soil and taking care of it so they would not be hungry, naked, homeless, and breathless.

Canopy Color Detection as a Proxy for N status

Optical sensors are promoted as a technique to monitor in-season nitrogen status of cereal crops, especially corn. This webinar will introduce CCAs to various sensors and the factors to consider in order to interpret the sensor output.

Drawing on over 100 on-farm trials in corn, cotton, and wheat, factors favoring success will be laid out along with factors favoring failure. Sensor-based N management will be compared to producer-chosen N rates in terms of yield, N expense, and profit.

Speaker Information:
Peter Scharf, PhD
Professor and Nutrient Management Specialist
University of Missouri

Peter Scharf has spent 30 years studying nitrogen.  The vast majority of his research has been conducted on private farms, with over 200 on-farm field-scale studies and an additional 200 on-farm small-plot studies.  Some of these studies showed that the most profitable rate of N fertilizer for corn varies widely within a field, leading him to pursue ways to manage that variability.  He has concluded that corn color is a much more accurate predictor of the best N rate than any pre-plant diagnostic, and that canopy sensors are an excellent way to harness science in service to better farming.  He is also a strong advocate of using aerial imagery to evaluate and correct N loss in wet years, having seen a tremendous amount of yellow corn across the Midwest over the past seven years. After getting a BS at University of Wisconsin, He obtained his MS in Agronomy and PhD in Crop and Soil Environmental Science from Virginia Tech.

John Shanahan, PhD
Agronomy Research Manager
DuPont Pioneer

John Shanahan has spent his entire career working toward developing and providing growers with improved agronomic management solutions to increase profitability and reduce risk. He began his career as a professor and extension specialist with Colorado State University, and later joined USDA-ARS, working as a Research Agronomist at the University of Nebraska. He is currently an Agronomy Research Manager with DuPont Pioneer where he is responsible for coordinating Pioneer-sponsored agronomic research projects with university collaborators across North America.  He is also responsible for providing support to the Pioneer agronomy team on development of research trial protocols for on-farm agronomic studies conducted with growers across North America.  

He received a BS in Agronomy from University of Nebraska and an MS and PhD from Colorado State University.  His major fields of interest are agronomy, crop genetics and physiology, remote sensing, soil science and precision agriculture technologies. He has used his expertise in these areas to help develop remote sensing and other Precision Ag tools for diagnosing crop stresses and improving crop nitrogen management.   Dr. Shanahan has reported research results in numerous industry articles, peer-reviewed publications, book chapters, conference proceedings, extension publications, and popular press articles. He has delivered many presentations to sales professionals, growers, consultants, extension educators, and government personnel. He is member of the tri-societies (ASA, CSSA, and SSSA) and International Precision Ag Society, serving on editorial boards for these societies as well as being elected Fellow of American Society of Agronomy.

Improved Nitrogen Stewardship from the Bottom Up

Improvement of nutrient stewardship at the farm-gate needs to start with farmers learning more about the dynamics of soil plant-available N in relationship to N source, rate, time and placement within their field using their practices and collecting their data. We refer to this method of learning as On-Farm Discovery. Our webinar will focus on what ag industry and farmers need to do as a partnership to learn the 4Rs of nitrogen management for each farming enterprise.   Various tools will be discussed that can be utilized to explore and learn more about Minimizing environmental impact by Optimizing harvest yield and Maximizing N utilization. It is all about focusing on M.O.M.
