Format: Oral Topical Session
Keywords: denitrification, nitrate nitrogen, subsurface drainage and water quality

Session Description: Nutrient losses from agronomic systems to surface and groundwater continue as a vexing problem associated with producing food for a growing population.  Denitrification is one process by which nitrate-N can be removed from agricultural runoff.  A number of practices enhance denitrification:  e.g. natural and constructed wetlands, saturated buffers, bioreactors.  This session is designed to bring together researchers and practitioners from the wide disciplines working on denitrification (e.g. subsurface drainage, microbiology, ecology, soil science, agronomy) to explore not only nitrate-N removal, but also total outcomes on water and environmental quality (nutrients and contaminants of emerging concern), gaseous consequences, and microbial effects.
