Inorganic Phosphate Solubilization in Soil

Pragya Rathore

Abstract :

Indian agriculture is mainly dependent on the extensive use of chemical fertilizers to raise crop yield. Since 70 to 90 % of the supplemented super phosphate is not available for crops as a result of mineralization the requirements for this fertilizer are high. Hence there is need to increase the effectiveness of low grade Indian phosphate rocks. Phosphatic biofertilizers offer a viable alternative as these organisms can be inoculated directly along with the low grade rock phosphate and applied to soils. In the present study an attempt has been made to isolate phosphate solubilizing bacteria from soil, study their phosphate solubilizing activity and their utility as biofertilizer. The organism, Citrobacter freundii, has been screened from the local soil samples of Malwa region and was selected for the further studies as it shows efficacious solubilization of phosphates and being indigenous it is well adapted to the environment where it can be used as a biofertilizer.
