Implementing constructed wetlands for nutrient reduction at watershed scale: Opportunity to link models and real-world execution.

ABSTRACT: The negative effects of nutrient pollution in streams, rivers, and downstream waterbodies remain widespread global problems. Understanding the cost-effectiveness of different strategies for mitigating nutrient pollution is critical to making informed decisions and defining expectations that best utilize limited resources, which is a research priority for the US Environmental Protection Agency. To this end, we modeled nutrient management practices including residue management, cover crops, filter strips, grassed waterways, constructed wetlands, and reducing fertilizer in the upper East Fork of the Little Miami River, an 892 km² watershed in southwestern Ohio, United States. The watershed is 64% agriculture with 422 km² of row crops contributing an estimated 71% of the
