Poster Session

S06 Soil & Water Management & Conservation 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 novel 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 and C sequestration, and sustain crop yields and quality.
