Phosphorous fertilizer component To isolate phosphorus from phosphate rock, it is treated with sulfuric acid, producing phosphoric acid. Some of this material is reacted further with sulfuric acid and nitric acid to produce a triple superphosphate, an excellent source of …
Phosphate Ion (PO43-) A phosphate ion is formed when three protons are removed from phosphoric acid ( H 3 P O 4). It is a polyatomic ion with the formula P O 4 3 −. It is also called a phosphate group. In this ion, the central phosphorous ion is surrounded by four oxygen atoms. Hence, it has a tetrahedral shape.
Phosphoric acid. Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H 2 PO 4-, derived from phosphoric acid, H 3 PO 4. The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.
Single Superphosphate (SSP) Impact Fertilisers has its own SSP manufacturing facility in Hobart, Tasmania. SSP is one of the most cost effective forms of phosphate and supplies sulphate sulphur and calcium. The ratio of phosphorus and sulphur suits many crop and pasture needs. Both the phosphorus and sulphur are in readily available forms.

SUPERPHOSPHATE Superphosphate is the fertiliser most commonly used in New Zealand to ensure that soil has a sufficiently high phosphorous c ontent. It is manufactured from the reaction between sulfuric acid and 'phosphate rock' (rock rich in the mineral fluorapatite, Ca5(PO4)3F): 2Ca5(PO4)3F + 7H2SO4 + 3H2O → 7CaSO4 + 3Ca(H2PO4)2.H
Normal Superphosphate. Normal superphosphate is a relatively dry, porous product consisting essentially of a mixture of monocalcium phosphate (a water-soluble phosphate salt) and calcium sulfate. Its available P2O5 content ranges from 18 to 22 percent, depending on the grade of rock and the free -moisture content of the final product.

Single superphosphate (SSP) was the first commercial mineral fertilizer, and it led to the development of the modern plant nutrient industry. This material was once the most commonly used fertilizer, but other phosphorus (P) fertilizers have largely replaced SSP because of its relatively low P content.
USES Low cost source of P and S in a wide range of pasture and cropping situations. SSP is a traditional product for supplying P and S to pastures, the main two nutrients required for pasture production. Source of P in mixes with N and K for a range of crop and pasture needs. Generally mixed with Sulphate of Ammonia and Muriate of Potash, but can be blended ...

History. Egyptians, Romans, Babylonians, and early Germans all are recorded as using minerals and/or manure to enhance the productivity of their farms. The use of wood ash as a field treatment became widespread. Fish was used as fertilizer, at least as early as 1620. In the 19th century, guano, which had been known and used in the Andes for at ...
One of the important phosphates is calcium phosphate, Ca 3 (PO 4) 2. The most important phosphorus fertilizer is monobasic calcium phosphate, called superphosphate [Ca (H 2 PO 4) 2 ], derived by treating rock phosphate with sulfuric acid (or phosphoric acid). Superphosphate is soluble in water and acts as a carrier of phosphorus needed by plants.
The key difference between single superphosphate and triple superphosphate is that single superphosphate is produced from phosphate rock and sulfuric acid, whereas triple superphosphate is produced from phosphate rock and phosphoric acid.. Superphosphate is a group of fertilizers which provides the crops with phosphate mineral element. There are three major types of …
Process for the production of urea superphosphate, which comprises reacting ground urea and ground phosphate rock with sulfuric acid in a single stage, in the presence of gypsum or phosphogypsum, or calcium sulfate monohydrate or anhydrous. Phosphoric acid may be added to the reaction mixture. The reagents may be added simultaneously to a reactor.
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. Rock phosphate treated with phosphoric acid ...
A superphosphate fertilizer is made with a process that involves creating a reaction between the raw phosphate rock and an appropriate percentage of sulfuric acid and water. The process that creates superphosphate fertilizers releases chemicals into the air, adding to air pollution and water pollution. Controlling these waste products means producing the fertilizer in a complicated process ...
Phosphoric acid (H3PO4) can be produced by 3 main commercial methods: wet process, thermal process and dry kiln process. Wet process is by far the most common route and the acid can be used in phosphate fertilizers production (DAP, MAP, SPA).

Fluorene occurs ubiquitously in products of incomplete combustion, in cigarette smoke, in sewage sludge (1) and in exhaust from gasoline engines (1,2). Fluorene is released to the atmosphere in emissions from the combustion of biomass, coal, polymers, tobacco, refuse (3), newspapers and wood (3,4).
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.
