Phosphorus and iron adsorption characteristics of acid saline soils of Kuttanad, Kerala

Abstract

An effort was made study [lit.1 phosphorus and iron adsorption characteristic^ of the acid saline soils of Kuttanad, Kerala. Thcrmodynamic parameters of I1 adsorption also were workecl Oul. phosphorus adsorption hv these soils was s;iiislactorily described by Langnmir. [•a'undSitli .nid Temkin equations. Iron adsorpiion did mil follow any of these equalions consistently indicating that adsorption is not a mechanism of inactivation of iron m these soils, .Study of the Ihemiodynaniic parameters revealed thai p adsorption in these soils was spontaneous, endothermic and highly disordered.
