Triple Superphosphate is a popular source of phosphate nutrient in legumes (peas, lentils and beans) which do not require additional nitrogen fertilisation.
TSP is a highly concentrated and water soluble greyish, granular phosphate fertiliser with a P₂O₅ availability of more than 46%. To produce TSP, rock phosphate is mined and treated with sulphuric acid. The result is phosphoric acid which gets reacted again with the rock phosphate in order to obtain the high concentration of P2O5 in the fertiliser. The active ingredient of TSP is (Mono-)Calcium Phosphate.
• Can be one of the cheapest sources of phosphorus available.
• It can be used in most situations where only phosphorus is required, or in a wide range of blends
