It is very usefull and effective in neutral, saline, and alkaline soils. It enhances the growth of soil micro organisms that assis the dissolution of phosphate in the soil. In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production. The solubility depends upon PH of the soil, ambient condition and bacteria present in the soil.
