Summary
The effectiveness of associating anions in reducing phosphorus retention in soil depends considerably on their physicochemical nature and the conditions under which they react with soil constituents especially the pH of the reaction medium. Organic anions, in general, are found to be superior to inorganic anions and the performance of silicate is best among the inorganic anions and in some cases its performance is comparable to those of organic anions. Organic anions are highly effective in reducing phosphorus retention in soil in an acid medium while the inorganic anions are found to be more effective under slightly acidic to neutral conditions. Citrate, however, is found to be most effective under a neutral condition. The concentration of associating anions should be at least of the same order as that of phosphorus in solution in order to be most effective in reducing phosphorus retention in soil. Higher levels of anion concentration do not exert any remarkable effect on phosphate retention reactions.
