Description

Water quality is a major issue in Iowa. Many of the state’s surface waters are impacted by nitrogen and phosphorus pollution from agricultural land. These nutrients promote excessive algal growth, which can deplete oxygen in the water, threatening fish and other aquatic life. The polluted waters eventually flow into the Mississippi River and are largely responsible for the hypoxic zone in the Gulf of Mexico. In response to these issues, the state of Iowa created the Iowa Nutrient Reduction Strategy. One part of this plan is the implementation of best management practices (BMPs) on agricultural land across the state. BMPs or Conservation Practices (CPs) are structures or farming methods that reduce nutrient export from agricultural operations. Despite significant financial and research investment into developing and promoting these practices, Iowa lags behind other Midwest states in implementation. A systematic literature review was conducted to analyze current adoption research. Themes were identified in the literature and grouped into categories based on frequency. Using these results, recommendations for further research are proposed as well as suggestions to increase adoption.
