Information

Dr. Kay Stefanik is the Assistant Director of the Iowa Nutrient Research Center.  She works to promote the adoption of conservation practices to reduce nutrient loss from agricultural settings.  Her expertise is in wetland ecology and aquatic biogeochemistry.  She has studied nitrogen and phosphorus transport through watersheds in the Ohio River Basin, as well as gaseous carbon cycling and vegetation succession in created and restored wetlands.
