The majority of agronomic soils have substantial stocks of total phosphorus, but phosphorus deficit is caused by phosphorus fixation and precipitation, which severely limits crop development. Soil samples were collected from rhizosphere of the plant in depth of 0 – 15 cm. Soil samples were serially diluted and plated Pikovskaya’s medium and incubated for 24 to 48 hours. Phosphate solubilization bacteria showed the development of clear zones surrounding the colonies on the plates. The phosphate-solubilizing bacteria were characterized using biochemical assays and colony morphology and growth patterns. The obtained phosphate-solubilizing bacteria were characterized by biochemical assays and confirmed to be as Pseudomonas fluorescens. The aim of this study is to isolate phosphate solubilising bacteria and study the mechanism of it.
