Determination of Phosphorus Adsorption Using Various Forms of Isotherms in Soils of Ad?yaman ?amgazi Plain

摘要

Samples from 8 widespread soil series from Ad?yaman ?amgazi Plain were equilibriated at a constant temperature with 16 different solutions containing 0 to 50 m g/ml phosphorus in batch-type experiments. The phosphorus concentrations of the equilibrium solutions and the amounts of phosphorus adsorbed by the soils at these concentrations were determined. These phosphorus-adsorption data were evaluated statistically for their suitability for adsorption isotherms in various concentration ranges.
