Phosphorus Equilibrium Characteristics for Soils in the Upper Eau Galle River Watershed, Wisconsin

摘要

The purpose of this demonstration was to examine phosphorus adsorption-desorption and equilibrium characteristics for soils collected from different land use practices in the Upper Eau Galle River watershed (Wisconsin). Land use practices included grazed pasture, row and perennial crop production, conservation reserve program or fallow land, and woodlots. This information will be important for watershed model algorithm improvements and applications that require categorization of soils as a function of phosphorus (P) concentration and equilibrium characteristics.
