- Abstract
This article discusses the loss of phosphorus from agriculture in relation to storm size in the Susquehanna River Watershed, Pennsylvania. According to the authors, storm flow accounted for about a third of watershed discharge, but more than half of phosphorus exported. Two storms contributed nearly a quarter of the phosphorus exported in four years. They suggest that area of the watershed producing runoff and/or phosphorus release from soil increase with storm size. They recommend that Best Management Practice considers acceptable levels of risk management regarding phosphorus loss.
