Occurrence of inositol hexaphosphate in some humid tropical soils
and
The inositol hexaphosphate content of several humid tropical oil was determined in the laboratory using two methods. The values of 16 surface oils ranged from 12 to 109 p.p.m. for the Caldwell and Black method and 13 to 124 p.p.m. for Anderson's method. The former method gave much lower values than Anderson's presumably because of incomplete precipitation. The inositol hexaphosphate content was significantly correlated with nitrogen total phosphate, inositol phosphates and orthophosphate retention capacity of the soils.
