Abstract:The continuous shaking trials were conducted to preliminarily study the effect of the different water-dissolved organic polymeric compounds-polyvinylalcohol (PVA), polyacrylamide (PAM) and polyethyleneglycol (PEG), on the kinetics of P adsorption in red soils. The results indicated that power-function model had been interpreted as an optimum indication of P adsorbed process in virtue of the compounds application, and the parameters in model of the compounds treatments were significantly different from that of the treatment alone applied monocalcium phosphate (MCP). The P adsorption and pH in soil were increased by the application of PVA, PAM or PEG, but the quantities of adsorption among the treatments applied them were not remarkably different.
