The inorganic soil phosphorus of the upper three horizons of 16 profiles was fractionated. The soils were selected to provide for a comparison of four kinds of parent materials and two great soil groups. The data show that, in general, the four glacial parent materials had similar proportional amounts of the inorganic P fractions. Climate, as expressed through great soil group, did affect the proportional amounts of two of these fractions, however. Among Chernozem soils the Fe‐P fraction makes up a proportionally larger amount, and the Ca‐P fraction a proportionally smaller amount, than they each do in Chestnut soils. Neither parent material nor climate alters the proportional amount of Al‐P present in these soil series.
