Superphosphate, 0-20-0, is made when rock phosphate is treated with sulfuric acid to make calcium phosphate (0-20-0) and calcium sulphate (gypsum.) Triple Superphosphate, 0-46-0, is made by treating rock phosphate with phosphoric acid. Triple Superphosphate has a much higher phosphate content, as indicated by the 0-46-0 indicating 46% phosphate ...

Jul 18, 2020· 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 ...

Single superphosphate labeled with the 34S isotope was obtained from a chemical reaction in stoichiometric amounts between Ca(H2PO4)2 and Ca34SO4.2H2O. .
Triple superphosphate plants are more capital-intensive but with a more concentrated product these plants can service a greater area. However, this product does not contain sulfur whereas superphosphate contains 13% sulphur. In many parts of the world areas of sulfur deficiency are showing up, and there is a trend back to single superphosphate.
Chemical industry - Chemical industry - Potassium: The simplest part of this diagram is the portion representing potassium. The element potassium is seventh in order of abundance in the Earth's crust, about the same order as sodium, which it resembles very closely in its properties. Although sodium is readily available in the sodium chloride in the ocean, most of the potassium is contained ...
Diammonium phosphate (DAP) is the world's most widely used phosphorus fertilizer. It's made from two common constituents in the fertilizer industry, and its relatively high nutrient content and excellent physical properties make it a popular choice in farming and other industries.

Jun 09, 2020· Single superphosphate is 20 percent phosphorus while triple superphosphate is around 48 percent. The standard form also has plenty of calcium and sulfur . It is commonly used on vegetables, bulbs and tubers, blooming trees, fruits, roses and other flowering plants.
Dec 09, 2011· Triple superphosphate is a fertilizer with the formula, Ca(H2PO4)2. In the industrial preparation of this fertilizer, phosphate rock is treated with phosphoric acid. If the balanced equation is Ca3(PO4)2 + 4H2PO4 --> 3Ca(H2PO4)2 What is the limiting reactant if 1000 kg of 42% pure phosphate rock is treated with 900 kg of phosphoric acid?
3. Sulfuric acid is one of the most important industrial chemicals. 9. Outline three uses of sulfuric acid in industry. Sulfuric acid is used in the manufacture of fertiliser. 70% of the world's production of sulfuric acid is used in superphosphate manufacture. Ca 3 (PO 4) 2 + 2H 2 SO 4 → Ca(H 2 PO 4) 2 + 2CaSO 4
The production of inorganic superphosphate and mixed fertilizers began soon after John B. Lawes and James Murray separately patented processes in 1842 in England for the prouction of superphosphate by treating bone and apatite ⠀ with sulfuric acid ⠀䨀Ⰰ 㤀㘀㐀.
ADVERTISEMENTS: In this article we will discuss about the production of various bio-fertilizers. 1. Production of Bacterial Bio-Fertilizer: With day-by-day increasing the population, especially in developing countries like India, the stress on agriculture is also increasing continuously. With the development, the land area under farming is not increasing but is further decreasing, this has ...
Normal superphosphate has a relatively low concentration of phosphorous, however it is used in mixtures because of its low cost. Triple superphosphate provides a high concentration of phosphorous, more than 40% phosphorous pentoxide. The industrial processes for each of these products are described below.

Superphosphate is suitable for use on all types of soils and for all crops. But on acidic soils it is difficult for plants, so it should be deoxidized with lime or ash: make 200 g of ash or 0.5 kg of lime per 1 m². Remember that superphosphate can be applied to the soil not earlier than a month after deoxidation, otherwise it will lose most of ...
