Abstract
Abstract Recovery of P by Ti from six soils of variable characteristics has been improved compared to those obtained with the previously published procedure, being now equal to or larger than the inositol P fraction as measured by other methods in current use. Paper partition chromatography has resolved the P material into two and sometimes three P entities, but these materials do not show as polyols with the ethanolic‐AgNO3 spray reagent. The materials are poorly resolved from Dowex‐1 formate resin but are somewhat better separated in an HCl system. These and other tests indicate that the soil organic P material recovered by Ti precipitation contains other components resistant to hypobromite oxidation besides inositol P esters.
