Challenges and Opportunities For Drawing Down High P Soils

Poster Session

ASA Section: Environmental Quality

Elevated levels of phosphorus in agricultural soils represent an on-going, or "legacy" source of elevated phosphorus in runoff water. Understanding the longevity of these elevated P levels, and developing effective methods to draw down high P levels in soils will enable better prediction of the effectiveness of management changes for improving water quality.
