Controlling Nutrient Losses From The Mississippi River Valley

Poster Session

ASA Section: Environmental Quality

Nutrient enrichment of the outlow from the Mississippi River has been implicated in Hypoxia in the Gulf of Mexico, and rnoff from agricultural land contributes to that enrichment. Effective and economical methods will be required to avoid, control and treat nitrogen and phosphorus losses from the Mississippi River watershed to meet water quality guidelines while maintaining crop productivity.
