A method for the determination of phosphate in citric acid extracts, without previous oxidation, is given. The effect of citric acid and molybdate concentration has been investigated. It is shown that the effect of citric acid can be overcome by increasing the concentration of molybdate reagent. Consideration has been given to the differences in the phosphate content of soil extracts as given by the direct and oxidation methods of determination.
