Which of the following cannot be used as phosphatic fertilizer:
Correct answer: C. Ca3(PO4)2
- A. CaH3PO4
- B. (NH4)2HPO4
- C. Ca3(PO4)2
- D. P2O5
Explanation
Calcium phosphate is a naturally occurring mineral that is not directly usable as a phosphatic fertilizer. While it contains phosphorus, the phosphorus in calcium phosphate is not readily available to plants because it is insoluble in water. It needs to undergo chemical reactions or microbial processes to become accessible to plants.
