Present paper deals with the characteristics of phosphate desorption isotherms of soils and clay mineral and P desorption with various extraction solutions. Isothrrmal adsorption of samples was first made and then phosphated sample were continuously desorbed by mean of the extraction with 0.5 N HOAc, 0.5 N NH4F and 0.1 N NaOH or with 0.5 N NH4F only.
