Labile and organic phosphorus (P) and sorbed P are required as the minimum data set to run a soil-plant P cycling model recently developed for continental U.S. soils. Labile and organic P and P sorption index were related to physical and chemical properties of 23 calcareous (greater than 50 g kg-1 CaCO3 content) and 32 highly weathered soils (greater than 30% Al saturation), to allow estimation of these P forms from readily available soil data. The P sorption or fertilizer AV index was estimated as the fraction of fertilizer P remaining as labile (resin extractable) P following incubation of soil and fertilizer. Labile P was linearly related (R2
