Phosphate Fertilizers
DAP (Diammonium Phosphate), NPK (Nitrogen, Phosphorus and Potassium) and TSP (Triple superphosphate) are phosphate-based fertilizers. Plants need three key macronutrients to grow: nitrogen (N), phosphorus (P), and potassium (K). Phosphorus that plays an essential in plant’s life and can be found in the environment as phosphates. Phosphates are extracted from phosphates rock that can be mined in a few deposits in the world. To date, there is no substitute or synthetic for phosphorus. DAP is the most common phosphate fertilizer and is produced by reacting phosphoric acid and ammonia. TSP is made by reacting wet-process phosphoric acid with phosphate rock. NPK is a mixture of ammonium nitrate, phosphates, potassium salts, inert fillers (such as limestone), coating materials and secondary nutrients. These fertilizers are not harmful to humans although prolonged contact may cause some irritation.
