Summary The concept of chemical potential was applied in studying the form of soil phosphate present in some Manitoba soils. Generally for all the soils studied, the soil phosphates were more soluble than hydroxyapatite but less soluble than dicalcium phosphate dihydrate. Evidence was obtained for the existence of octocalcium phosphate in most of these soils. The effect of phosphate fertilization and per cent calcium carbonate on the form of native soil phosphate was also evaluated.
