Role of Aspergillus niger in Solubilizing P in Togo Rock Phosphate during Composting with Different Organic Wastes

The immobilization and mineralization processes carried out by soil microorganisms have a significant role in controlling the availability of phosphorus soil. A class helpful known as phosphate solubilizing microbes are able to hydrolyze insoluble organic inorganic compounds into soluble P (phosphorus) form that is readily taken plants. objective this study was evaluate different waste Aspergillus niger Togo rock during composting. Composts were prepared using rice straw citrus had been inoculated with supplemented phosphate. results showed co-inoculation system PSF (i.e. niger) provided optimum condition for solubilization.
