Managing Watershed Agricultural Contaminants in Northeast Iowa

John Rodecap, Extension Program Specialist III, Agronomy

Situation 

Bringing partners together to test innovative programs for solutions to non-point source contamination.

Objective 

To demonstrate locally-based refinement of practices using watershed leaders to assist in the discovery and confirmation of results and distribution of those results to neighbors.

Activities/Output 

Iowa State University (ISU) Extension specialists have assisted individual producers and watershed councils to develop performance-based soil and nutrient management in contaminant threatened watersheds in northeast Iowa.  Iowa Corn Grower and Iowa Farm Bureau Federation financial support was secured to encourage on-farm demonstrations that have aided in bringing new technology including GIS-GPS and management practices that have resulted in refined tillage, planting, manure application and nutrient use on watershed farms.

Impact/Outcomes 

The results of significant reduction recommendations in nitrogen and phosphorus use are shared among watershed councils and communities in the region.
