Objective: Identify phosphate solubilizing activity of strains of the genus Bacillus, as an alternative to improving soil for agricultural production. Materials and methods: For the study, 11 strains of the genus Bacillus were collected from rhizosphere of plants and fireplaces of broiler chicken producers. Two strains were used as negative control, and stored at -70C prior to reactivation for identifying phosphate solubilizing activity. Results: 11 strains showed Phosphate solubilizing abilities. Each strain studied exhibited different solubility rates
