Weband o-phosphate adsorption data are required to de-termine the model parameters. Four independent pa-rameters must be adjusted to describe the adsorption of a single o-phosphate species. The Constant Capac-itance model successfully describes pH effects on o-phosphate adsorption by goethite (Stumm et al., 1980; Sigg and Stumm, 1981). WebAdsorption and Desorption Adsorption is the chemical binding of plant available P to soil particles, which makes it unavailable to plants. Desorption is the release of adsorbed P from its bound state into the soil solution. Adsorption (or “fixing” as it is sometimes called) occurs quickly whereas desorption is usually a slow process. green touches cleaning services
