Superphosphate is the first chemical fertilizer. It was first made in about 1840 from bonemeal and sulfuric acid. Shortly later, superphosphate was made from rock phosphate ore by treatment with sulfuric acid. This material is called ordinary superphosphate or single superphosphate and is 0-20-0-11S.

Making superphosphate. Phosphate is a naturally occurring form of the element phosphorus, present in all living cells. It is found in the fossilised remains of ancient marine creatures, and in large build-ups of droppings (guano), which form sandy deposits known as rock phosphate. Making superphosphate involves chemically treating rock ...

Le principal avantage du superphosphate ammoniac est qu'il ne contient pas de gypse, qui est peu soluble dans l'eau. En plus du phosphore (32%), de l'azote (10%) et du calcium (14%), 12% de soufre est présent dans l'engrais ammoniac, jusqu'à 55% de sulfate de potassium. Ce superphosphate est précieux pour les oléagineux et les cultures de …

Triple Superphosphate Triple superphosphate (TSP) was one of the first high-analysis phosphorus (P) fertilizers that became widely used in the 20th century. Technically, it is known as calcium dihydrogen phosphate and as monocalcium phosphate, [Ca(H₂PO₄)₂ .H₂O]. Despite its excellent history as a P source, its use has declined as other P …
