ABSTRACT

Phosphorous is one of the important nutrients required in the plant development and majority of the plant growth. Good percentage of phosphate-solubilizing microbes is present in the rhizosperic layer and they are more active metabolically than other sources. Microbes solubilizing of phosphate correlative with property of microorganisms producing selected organic acids and extracellular polysaccharides. Plants acquire phosphorus from soil as phosphate ion. It's the smallest amount mobile component in plant and soil contrary to alternative nutrients. The phosphate ion precipitate in the form of orthophosphate in the soil. It is also absorbed in the soil by iron and aluminum oxide. The absorption takes pace with the help of legend exchange. Phosphorus solubilizing microorganism plays very important role by enhancement of phosphate handiness to the pants. The phosphate solubilizing microorganisms solubilize and mineralize the soil which helps in the release of organic and inorganic form of phosphorus. The phosphate solubilizing bacteria lowers the pH of soil and hydrogen ion concentration by bacterial production of organic acids, the phosphate solubilizing bacteria with the help of acid phosphatase enzyme, mineralize the organic phosphorus. Use of PSB as inoculants will increase Phosphate intake in plants. These bacteria additionally increase the utilization of phosphorus rocks in the production of crop in agriculture. Bigger potency of the bacteria that solubilize phosphate can be detected through the co-inoculation with alternative useful microorganism and mycorrhiza.
