Single superphosphate(TSP)

TSP is a solid single-nutrient phosphate fertilizer material produced from phosphate rock and phosphoric acid. TSP typically contains 44–46% anhydrous phosphoric acid (P₂O₅), more than twice the P₂O₅ content of normal superphosphate.

Normal superphosphate or single superphosphate (NSP, SSP) is used solely as a fertilizer material. NSP can be used with most crops and is applied during the planting season. NSP is a solid phosphate fertilizer material that is produced from phosphate rock and sulfuric acid (H₂SO₄).
