The modern agriculture is dependent on phosphorus (P) derived from phosphate rock. However, the direct application of low-grade rock phosphate as a P source in soils need an addition of inoculums of phosphate solubilising microorganisms to improve the rock phosphate efficiency as a phosphorus source. Phosphate solubilising bacteria (PSB) were screened for their phosphate solubilising ability ...
