| Abstract |
In search of a better approach to predict phosphorus movement in soils from applied wastewaters, reactions of added orthophosphates were studied in 9 different soils with widely varying physical and chemical properties. Information obtained on the nature and rate of P reaction will be coupled with P adsorption data to derive mathematical models for P movement in soils from applied wastewaters. Compounds having higher solubility than variscite were formed which changed to crystalline variscite with time upon adding Ca(H2PO4)2.H2O to acid soils. Monocalcium phosphate monohydrate in alkaline soils transformed to relatively insoluble CaHPO4.2H2O, CaHPO4, Ca3(PO4)2, Ca4H(PO4)3.2 1/2 H2O, and Ca10(OH)2(PO4)6. The rate of transformation in both acid as well as alkaline soils was P rate dependent; slower with increased P rates. |
