Soil microorganisms play an important role in soil processes that determine plant productivity. Phosphate solubilizing Bacteria (PSB) is the important microbial group associated with plant nutrition. They are capable of hydrolysing organic and inorganic phosphorus from insoluble compounds. P-solubilization ability of the microorganisms is considered to be one of the important characteristic features for soil fertility, plant growth and potential yield. PSMs include different groups of microorganisms, which not only assimilate phosphorus from insoluble forms of phosphates, but they also cause a large portion of soluble phosphates to be released in quantities in excess of their requirements. Termite soil contains microbial population which are capable of mobilizing important nutritional elements in the soil. This group covers bacteria, fungi and some actinomycetes. These organisms solubilize the unavailable forms of inorganic-P like tricalcium, iron, and aluminum into soluble forms by release of a variety of organic acids. Termite mound material is used as an ecofriendly approach to minimize the use of chemical fertilizers, for enhancement of crop production by their biological activity.
