Phosphorus Transport from Delaware's Rural Watershed

by William F. Ritter, Univ of Delaware, Newark, United States,



Document Type: Proceeding Paper

Part of: Structures for Enhanced Safety and Physical Security

Abstract:

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.
