Potassium sulfate is a colorless crystal with low hygroscopicity, not easy to agglomerate, good physical properties, easy to apply, and is a good water-soluble potassium fertilizer. Potassium sulfate is also a chemically neutral, physiologically acidic fertilizer. Potassium sulfate is a kind of chlorine-free, high-quality and high-efficiency potassium fertilizer, especially in the planting of chlorine-sensitive crops such as tobacco, grapes, sugar beets, tea trees, potatoes, flax and various fruit trees. It is an indispensable important fertilizer; it is also a high-quality fertilizer. The main raw material of nitrogen, phosphorus and potassium ternary compound fertilizer.
Potassium sulfate compound fertilizer is produced by low-temperature conversion of potassium chloride, chemical synthesis, and spray granulation process. It has good stability. In addition to the three main nutrients necessary for plants, N, P, and K, it also contains S and Ca. , Mg, Zn, Fe, Cu and other trace elements. This kind of fertilizer is suitable for various economic crops, especially those sensitive to chlorine. The main components of potassium sulfate type compound fertilizer are MAP (monoammonium phosphate), DAP (diammonium phosphate), and ammonium sulfate (mainly obtained by low-temperature conversion of surplus sulfuric acid and ammonia gas). Potassium sulfate, urea and other impurities such as calcium sulfate, phosphoric acid iron, aluminum, magnesium and other salts, as well as trace amounts of unreacted potassium chloride.
