Phosphorus loads were estimated for 62 watersheds. Major land uses in the watersheds were cropland and forestland. Annual phosphorus loads varied from 0.42 to 1.19 kg/ha. Watersheds with over 60% cropland had higher phosphorus loading rates than watersheds with more than 40% forestland. Poultry production in the watershed had some influence on the phosphorus loading rate.
