Mineralization of inositol penta and hexaphosphates in some soils of Bangladesh

Abstract

The nature of iP;, and changes iP^ in Bangladesh soil* has been examined. Mineralization of iP^ and ipj was found at all moisture levels cither alone or with lime. A rapid mineralization occurred in the first 30 days followed by a moderate disappearance in the next 30 days in all treatments. Maximum mineralization of iPj and iPj occurred in submerged condition with lime. The hydrolysis was greater in soils containing more organic matter and iPu and ipj. Mineralization also increased with pH for inducing conditions to proliferate of the phytase for the breakdown of ipj and iP.
