Phosphorus is largely retained in soil by a process called adsorption. . Soils . have a limited capacity to store phosphorus, and once the capacity of soil to adsorb phosphorus is exceeded, the excess will dissolve and move more freely with water either directly to a stream or downward to an aquifer. . Alexandra Arntsen, Alison Foster, Scott Ritter. April 2011. Problem Statement:. . Excess phosphorus loading in Lake Champlain is affecting overall water quality through increased growth rates of photosynthetic aquatic plant life and the subsequent reduction of dissolved oxygen. .
