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