SSSA Division: Soils & Environmental Quality Session: Nitrate Leaching: What Have We Learned and Where Do We Go from Here? (ASA, CSSA and SSSA International Annual Meetings)

173 Nitrate Leaching: What Have We Learned and Where Do We Go from Here?

Oral Session

SSSA Division: Soils & Environmental Quality

Nitrate leaching into groundwater is becoming a larger problem across the globe, and sound scientific studies are needed to address this major problem. This topical session will focus on examining nitrate leaching results, research methods, and successful approaches used in minimizing leaching. Abstracts that integrate two or more of these topics are especially encouraged.
