2021: The Revised Reporting Structure for the Iowa Nutrient Reduction Strategy

From 2014 to 2020, a comprehensive report was released annually by Iowa State University, Iowa Department of Agriculture and Land Stewardship, and Iowa Department of Natural Resources to provide updates on nutrient reduction efforts pertaining to the Iowa Nutrient Reduction Strategy. Beginning in 2021, a revised reporting structure was adopted to release web-based data dashboards, centering on the four dimensions of the Strategy's Logic Model approach. This revised structure facilitates a more timely and transparent release of data and findings. Reports, dashboards, and findings that are released in 2020 or later are available on this page.
