Quick Summary

Superphosphate is a soluble mixture of phosphates used as a fertilizer. It is created by treating insoluble mineral phosphates with sulfuric acid. This process converts the insoluble tricalcium phosphate found in phosphate rock into a water-soluble form, monocalcium phosphate, which plants can absorb. Superphosphate is also referred to as an acid phosphate. The chemical industry produces fertilizers, including superphosphate, to add essential elements like phosphorus to the soil for agricultural purposes.123
