Isolation And Characterization Of Phosphate Rock-Solubilizing Microorganisms From Soils And Rock Phosphate Samples Of Panda Hill And Minjingu, Tanzania

ABSTRACTPlants acquire P from soil solution as the phosphate anion. Phosphorus for plant can be obtained from soluble P fertilizers or from insoluble phosphate rocks. It is highly fixed by calcium and by Fe and Al oxides depending on soil pH. Phosphorus solubilizing microorganisms play a major role in P nutrition through solubilisation of insoluble phosphate rocks. The use of phosphate solubilizing microorganisms as inoculants increases P uptake by the plant and crop yield. This study was und...
