Session: Agricultural Practices to Improve Nitrogen-Use Efficiency and Mitigate Greenhouse Gas Emission Oral (ASA, CSSA and SSSA International Annual Meetings (2016))

47 Agricultural Practices to Improve Nitrogen-Use Efficiency and Mitigate Greenhouse Gas Emission Oral

Oral Session

ASA Section: Environmental Quality

Large amounts of N fertilizer are applied annually to cropland because N is the most limiting nutrient for crop production. Therefore, N leaching into groundwater and N₂O emission could have major environmental implications on water quality and global warming. In general, agricultural practices contribute about 70% of global N₂O emissions. This session will address management practices, such as types and rates N fertilization, cover crop, crop rotation, tillage, etc. that enhance crop N-use efficiency, reduce N losses through emission or leaching, and maintain crop yields.
