Phosphoric acid in fertilizer improves its performance. Good fertilizer produces a good crop.Mineral fertilizers play a key role in achieving the expected yields and yields of farmers and the needs of the world’s growing population.As economic pressures mount on farmers, improving yields becomes a vital necessity. Optimizing farm inputs is a way to reduce costs while controlling yields. One of the most important agricultural inputs is mineral fertilizer. This source comes from various sources around the world and can be of variable quality.Phosphoric acid (PA) is an important industrial chemical used as an intermediate in the fertilizer industry, for surface treatment of metals in the metallurgical industry, and as an additive in the food industry. PA industry has expanded worldwide in Europe, Asia and the United States, including countries that manage phosphate (PR) mines. Phosphoric acid is found in phosphate fertilizers and phosphate-based products.Fertilizer production accounts for about 90% of the global market for phosphoric acid and animal feed for about 6%. The rest is used in a variety of industrial applications.
Phosphorus is an essential nutrient for plants and is absorbed by plant roots, usually as the dihydrogen phosphate ion, H 2 PO 4 – derived from phosphoric acid, H 3 PO 4. The production of fertilizers used to address phosphorus deficiency in the soil depends on the availability of phosphoric acid sources.About 90% of the phosphoric acid produced is used to make fertilizer. This substance is mainly converted to three phosphate salts which are used as fertilizer. They are triple superphosphate (TSP), diamonium hydrogen phosphate (DAP) and monoammonium dihydrogen phosphate (MAP).To produce phosphorus fertilizer, the stone is treated with sulfuric, phosphoric or nitric acid. Each method has its advantages and limitations. The sulfuric acid pathway produces little phosphorus fertilizer, like single superphosphate, which is semi-gypsum. The use of phosphoric acid in fertilizers produces higher concentrations of phosphorus this is a Applications Phosphoric acid.
The third production process is the use of nitric acid for the acidity of rock phosphate. This process is a cleaner, waste-free process and produces two fertilizers:
Nitrophosphates combined with potassium produce complex NPK fertilizers such as YaraMila.
Phosphoric acid is made by two processes, the wet process and the thermal process.
The thermal method typically produces more concentrated and pure products, but has a lot of energy. The acid produced by the wet path is less pure and is used in the manufacture of fertilizers.The “wet process” acid product is not clean, but can be used to make fertilizer without further refining. Alternatively, it can be evaporated to about 70 ٪ P 2 O 5, a solution called superphosphoric acid, which is used directly as a liquid excretion fertilizer.Phosphorus fertilizers are produced from rock phosphate, but rock phosphate itself is rarely used directly as fertilizer due to the unavailability of phosphorus and transportation costs. Instead, milled granular phosphate is refined with sulfuric acid to produce monocalcium phosphate monohydrate, also known as superphosphate. About 85 to 90% of the phosphate in superphosphate is water soluble. In another process, milled phosphate reacts with sulfuric acid to produce phosphoric acid.
Phosphoric acid is not usually used as an feed directly as a fertilizer, but is used to make other fertilizers. The reaction of phosphoric acid with ground coagulated phosphate produces triple superphosphate (TSP). MAP and DAP are the products of the reaction between phosphoric acid and ammonia. Phosphoric acid can be produced by heating water to produce superphosphoric acid, which produces ammonium polyphosphate when it reacts with ammonia.Phosphoric acid per kilogram of phosphorus is more expensive than other fertilizers, but due to the ease of mixing the tank with other chemicals and superior crop yield (higher yield per kilogram of phosphorus used) in alkaline soils due to the neutralizing effect, upgrade Finds.
Phosphorus soil tests measure the soil’s ability to supply phosphorus to the soil solution for plant use, but do not measure the total amount of phosphorus available. These experiments provide an indicator of the availability of phosphorus in the soil, which is related to the ability of phosphate fertilizer to provide optimal economy. Increased performance The relationship between phosphorus determined by a soil test and phosphate fertilizer requirements has been developed from the results of several research experiments that measure different amounts of phosphate and yields used.If the level of phosphorus in the soil is not suitable for optimal crop growth, use phosphate fertilizers to ensure a sufficient amount of this nutrient in the solution stage.
