Answer: Option A

Solution

Answer: Option A
Solution:
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%.
Rock phosphate is the phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. It contains 20 - 30% of P2O5.
