Abstract:

In order to study the role of citric acid in soil genesis and material cycle, the advancement of interaction between citric acid and phosphorus had been discussed. The main contents were: (1) citric acid secretion and secretion mechanism; (2) citric acid secretion in phosphorus deficient; (3) effects of citric acid on adsorption of phosphate; (4) effects of citric acid on desorption of phosphate; (5) effects of manually adding citric acid to soils for reducing the application rates of in phosphorous fertilizers. Studies which were related of citric acid to phosphorus and phosphate fertilizer in the actual production remained to be strengthened.
