This study evaluated the effects of wetlands on water quality in the Minnesota River Basin (a subsection of the Mississippi River Basin, U.S.) by analyzing high-resolution land cover data and water quality data. The results indicate that wetlands are approximately five times more efficient at reducing riverine nitrate concentrations than land-based nitrogen mitigation strategies (including cover cropping).
