a. SSP	1. 40 - 48
b. TSP	2. 16 - 20
c. DAP	3. 20 - 30
d. Rock phosphate	4. 54

SSP (Single Super Phosphate) is the most popular phosphatic fertilizer. The percentage of P₂O₅ is approximately 16 - 20% in SSP.
TSP (Triple Super Phosphate), is a chemical fertilizer with a P₂O₅ content of over 40 - 48%.
DAP (Diammonium Phosphate) is a widely used phosphate-based fertilizer with a phosphorus content of 54%.
