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.
