Session Description: Nitrogen is a major limiting nutrient for crop production. As a result, substantial amounts of N fertilizers have been applied to sustain and/or increase yields. This has also resulted in major environmental consequences, such as N leaching in the groundwater and emission of N2O. Agricultural practices contribute about 70% of the global N₂O emission. This session will discuss agricultural management options, such as N fertilization, cover cropping, crop rotation, fallow management, tillage, etc. that reduce N fertilization rates to crops and greenhouse gas emissions, increase N-use efficiency reducing N losses via emission or leaching, and sustain crop yields and quality.  Graduate student contributing to this session are eligible to compete in the Soil Carbon and Greenhouse Gas Emission Community's graduate student competition for cash awards.
