DAP (Diammonium Phosphate), MAP (Monoammonium Phosphate) and TSP (Triple superphosphate) are the most commonly traded phosphate fertilizers. DAP is produced by combining phosphoric acid with ammonia. It contains 18% nitrogen and 46% phosphorus pentoxide. TSP is made by reacting wet-process phosphoric acid with phosphate rock.
