About the presentation

This distinguished lecture is part of ASAP's series “Farming, Food and Environment in a Changing World,”  and is being co-hosted by the Office of Research, College of Agricultural, Consumer and Environmental Sciences in association with the Soils and Carbon Communities of Practice.  This event is being cosponsored by the Environmental Change Institute.

Steve's presentation will address:

·         Processes that control plant/soil system C and N cycling

·         Quantifying C and N fluxes: uncertainty, scale dependency, farm level tools (COMET)

·         Mitigation strategies: improved soil/fertilizer management, biofuel cropping systems

About the presenter

Stephen Del Grosso is a Soil Scientist for the USDA Agricultural Research Service (ARS) in Fort Collins, CO. He is also affiliated with the Natural Resource Ecology Laboratory (NREL) at Colorado State University. He is responsible for estimating nitrous oxide emissions and nitrate leaching from agricultural soils for the annual EPA Greenhouse Gas Inventory and is the co-editor and co-author of the most recent USDA Agriculture and Forestry Greenhouse Gas Inventory. Dr. Del Grosso uses models to compare different mitigation strategies intended to reduce greenhouse gas emissions from cropped and grazed soils and to evaluate the net environmental impacts of different biofuel cropping systems. In addition to running models, he oversees a field experiment that investigates how crop rotations, fertilizer additions, and tillage practices interact to control greenhouse gas emissions and crop yields. Dr. Del Grosso received his Ph.D. and Master degrees from Colorado State University and his B.S. from Pennsylvania State University. His work has been reported in 30 peer reviewed journal articles, 20 book chapters, and various symposia and conventions in the US and abroad.
