ASA Section: Environmental Quality Session: Managing Denitrification in Agronomic Systems - Innovations and Challenges: I (ASA, CSSA and SSSA International Annual Meetings)

255 Managing Denitrification in Agronomic Systems - Innovations and Challenges: I

Oral Session

ASA Section: Environmental Quality

Various denitrification systems allow the removal of excess nitrate from agricultural drainage water. This session covers the biological, hydrologic and management aspects of natural and engineered systems for nitrate removal, including denitrification bioreactors, riparian biofilters, and wetlands.
