Uses: Generally used as buffer and culture medium in industry; Used as high-efficiency phosphorus and potassium compound fertilizer in agriculture; Food grade is used as food improvement additive.
Potassium dihydrogen phosphate can be widely used in almost all kinds of cash crops, grain, fruits and vegetables. Potassium dihydrogen phosphate has many functions, such as increasing production and income, improving quality, resisting lodging, pests and diseases, preventing premature aging and so on. It also has the function of overcoming nutrient deficiency caused by root senescence and decreased absorption capacity in the late growth stage of crops. Potassium dihydrogen phosphate is widely used in drip irrigation and sprinkler irrigation systems because of its good solubility. It is mainly used for foliar topdressing in field crop production, and water with concentration of 300-500 times is sprayed on the foliar. In recent years, the "three defenses" of wheat are often used as foliar fertilizer, which has the functions of increasing yield and resisting dry and hot wind.
Potassium dihydrogen phosphate (chemical formula: KH2PO4) is sealed and stable in air, and loses water at 400℃ to become metaphosphate, which is used to prepare buffer solution, determine arsenic, antimony, phosphorus, aluminum and iron, prepare phosphorus standard solution, prepare culture medium and determine the activities of inorganic phosphorus and alkaline phosphatase in serum.
