This study compared the watershed inputs, outputs, and retention capacities of nitrogen and phosphorus in seven subwatersheds in the Mississippi River Basin (MN, U.S.). In the largely residential sample sites, lawn fertilizer and pet waste were the primary contributors of nitrogen and phosphorus, respectively. The results indicate that managing nitrogen and phosphorus requires different strategies for each nutrient.
