The two present viewpoints which exist as to the origin and transformations of the soil inositol phosphates are discussed. Arguments are presented in favor of the first viewpoint which considers the direct microbial synthesis of the soil d ‐chiro‐, scyllo‐ and neo‐inositol hexaphosphates by reactions which do not involve epimerization. Considerable evidence is presented which indicates that a likely mechanism of synthesis of the soil d ‐chiro‐, scyllo‐ and neo‐inositol hexaphosphates is via an epimerization of myo‐inositol or its hexaphosphate. Studies with 14 C‐labeled myo‐inositol and myo‐inositol hexaphosphate are suggested to prove the microbial transformations which these compounds undergo in soils. Simultaneous studies with 14 C‐labeled carbon and 32 P‐labeled phosphate are also suggested to determine the fate in soils of each carbon and phosphorus atom of soil myo‐inositol hexaphosphate.
