355 Symposium--Phosphorus Fate, Management, and Modeling in Artificially Drained Systems: II

Oral Session
ASA Section: Environmental Quality
This symposium will (1) document the range of settings in North America where artificial drainage serves as a important pathway of phosphorus transfer from agricultural lands to surface waters, (2) review and evaluate options for managing phosphorus transfers to artificial drainage systems, and (3) assess the representation of important processes in models.
