Potassium Sulphate is a colorless crystal, with low hygroscopicity, not easy to agglomerate, good physical properties and convenient application. It is a good water-soluble potassium fertilizer. Potassium sulfate is also a chemically neutral, physiologically acidic fertilizer. Potassium sulfate is a chlorine-free, high-quality and high-efficiency potassium fertilizer, especially in the cultivation of chlorine-sensitive crops such as tobacco, grapes, sugar beets, tea trees, potatoes, flax and various fruit trees. It is an indispensable and important fertilizer; Potassium Sulphate is also an important fertilizer. The main raw material of high-quality nitrogen, phosphorus and potassium ternary compound fertilizer.
Potassium sulfate type compound fertilizer is produced by low-temperature conversion of potassium chloride, chemical synthesis, and shotcrete granulation. , Mg, Zn, Fe, Cu and other trace elements. This fertilizer is suitable for various commercial crops, especially for chlorine-sensitive crops. The main components of potassium sulfate type compound fertilizer are MAP (monoammonium phosphate), DAP (diammonium phosphate), and ammonium sulfate (mainly obtained from the neutralization of excess sulfuric acid and gaseous ammonia converted at low temperature). Potassium Sulphate, urea and others also have some small amount of impurities such as calcium sulfate, iron, aluminum, magnesium and other salts of phosphoric acid and a small amount of unreacted potassium chloride.
