Conteúdo: 	The study consisted of a factorial experiment in which each of seven widely different soils was treated with 0 and 1 lime requirements and 0,500, and 1,000 ppm of P. Prior to fractionating the soil P, a constant amount of P was added to each sample. The results indicate that for these acid soils, P was extracted predominantly with the aluminum phosphate and iron phosphate fractions. Results for isotopic dilution indicated that the different P fractions ranked in the following order with respect to amounts of active solid phase P removed per unit of solid phase P: water soluble P> aluminun phosphate > iron phosphate > calcium phosphate.
