What is the difference between SSP and TSP?

Superphosphates are fertilizers that can provide phosphate minerals to plants. The main difference between simple superphosphate and triple superphosphate is that simple superphosphate is produced from phosphate rock and sulfuric acid, while triple superphosphate is produced from phosphate rock and phosphoric acid. We can denote single superphosphate as SSP, while triple superphosphate as TSP. In addition, phosphorus content is another difference between simple superphosphate and triple superphosphate. That is, single superphosphate has a low phosphorus content, but triple superphosphate has a high percentage of phosphorus (about twice the phosphorus content of SSP). In addition, simple superphosphate also contains small amounts of sulfur as a micronutrient, while triple superphosphate contains no other important plant nutrients. Therefore, the lack of micronutrients in simple superphosphate is less than triple superphosphate. But the amount of soluble phosphorus in triple superphosphate fertilizer is more than simple superphosphate fertilizer , Table 1- The difference between simple superphosphate and triple superphosphate.

Impact on soil

It makes the soil texture loose and the permeability of water and plant roots to absorb nutrients

It causes compaction and strengthening of the soil texture and reduces the permeability of the soil

Ca(PO4H2)2= Simple Super Phosphate(SSP) , Ca (PO4H2)2= Triple Super Phosphate (TSP)
