Potassium sulfate compound fertilizer

Potassium sulfate compound fertilizer is produced by low temperature conversion of potassium chloride, chemical synthesis and spray granulation. It has good stability and contains trace elements such as S, Ca, Mg, Zn, Fe and Cu, except for N, P and K three major nutrient elements necessary for plants. This fertilizer is suitable for all kinds of cash 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 neutralized by sulfuric acid and ammonia gas at low temperature). Potassium sulfate and urea have some other impurities, such as calcium sulfate, iron, aluminum and magnesium in phosphoric acid and trace potassium chloride.
