Apatite Control of Phosphorus Release to Runoff from Soils

Jan 11, 2009 Phosphorus P in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P DP concentrations about 0.43.0 mg L1 in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms.
