Seminar Descriptions:

October 12: Adaptive Nitrogen Management for Corn II: Implementation Using Field and Model Tools

This seminar focuses on implementation of an adaptive nitrogen management approach for corn production, and discusses appropriate tools.  Specific focus will be on the Adapt-N tool, which is a model that simulates nitrogen processes in the soil-crop system and derives nitrogen fertilizer recommendations.  The model is complex and uses high-resolution weather data (3x3 mi resolution) in its computations, but can be easily run through a user-friendly web interface.  The Adapt-N tool also provides insights into seasonal N losses and gains, and allows for end-of-season evaluation of N management practices.

This seminar is worth 1.0 Nutrient Management CEU and 1.0 Professional Meetings CEU for Agronomy & Soils certifications

Speaker Bios:

Dr. Harold van Es is Professor of Soil and Water Management and Chair of the Department of Crop and Soil Sciences at Cornell University.  Current research and extension interests are in precision management of crop inputs, soil health, tillage and compaction, chemical fate in soils, and space-time statistics.  He also teaches undergraduate courses in Soil Management for Sustainability, and a graduate course in Space-Time Statistics.  He has published over 100 peer reviewed papers and chapters, co-authored a widely-read book on sustainable soil management (Building Soils for Better Crops), developed videos in water quality management, wrote numerous extension articles, and advised 45 graduate students.  He leads the Cornell Initiative on Computational Agriculture.  He is a Fellow of the Soil Science Society of America and the American Society of Agronomy, and has served on US EPA scientific advisory panels.

Dr. Bianca Moebius-Clune is a Postdoctoral Associate in the Department of Crop and Soil Sciences at Cornell University. Current research and extension interests are in soil quality assessment, monitoring of human-induced soil change over time, and adaptive management of nitrogen inputs and soil health. She coordinates research and extension activities around the use of AdaptN for adaptive nitrogen management, and activities of the Cornell Soil Health Team, and teaches an undergraduate course in Soil Management for Sustainability. She has published a number of peer-reviewed and extension articles. She co-authored the Cornell Soil Health Assessment Training Manual that is used by growers and agricultural service providers in the United States and abroad, and the SSSA book Soil! Get the Inside Scoop for the opening of the Smithsonian exhibit on soils.

Part I held on Oct. 5: Adaptive Nitrogen Management for Corn I: Processes and Management Approaches

Nitrogen is often the largest monetary crop input for corn production and is of considerable environmental concern.  Nitrate leaching to water resources, including sensitive estuaries, is a persistent problem, and the greenhouse gas impacts from nitrous oxide gas losses will become a major issue in the next years.  These gaseous losses account for the largest fraction of the global warming impact from agriculture.  Adaptive management approaches attempt to optimize management practices for the specific conditions of a resource base.  With nitrogen management on corn this involves greater accounting of the various sources of gains and losses in a soil-crop system, including soil type effects, mineralization from organic sources, crop management practices, and the impact of seasonal weather conditions.  This seminar discusses these processes and provides background on the need for a dynamic and adaptive approach to nitrogen management for corn production, especially in humid regions.This seminar is worth 1.0 Soil and Water Management CEU for CCA and 1.0 Professional Meetings CEU for Agronomy & Soils certifications
