Soil Exchangeable Phosphorus Pools, Equilibrium Characteristics, and Mass Distribution Coefficients for Eight-Mile Run Watershed, Wisconsin

摘要

This research experimentally determined phosphorus mass distribution coefficients (i.e., relationship between soil exchangeable and soluble phosphorus), exchangeable phosphorus pools, and soluble phosphorus in the interstitial water for soils exhibiting a range of phosphorus concentrations. The research also developed relationships between these variables and commonly measured, crop-available soil phosphorus for use in establishing initial soil P parameters in the System-Wide Water Resources Program-Nutrient Sub-Model (SWWRP- NSM).
