Description
Double superphosphate is a phosphorus-containing fertilizer which has a moderate phosphorus content. Double superphosphate generally contains about 36% of phosphorus. We denote this fertilizer as DSP. It contains about twice the phosphorous content as single superphosphate. However, the characteristics, appearance and mode of action of DSP are mostly similar to those of SSP. The production process for DSP is similar to that of TSP production but the difference is in the concentration of the phosphoric acid that is used to treat the phosphate rock.
However, DSP is not commonly used in many places except Indonesia where its annual consumption is about 800,000MT
