Ammoniumsulfate is also used as a fertilizer (although in much higher concentrations), but it only contains nitrogen but neither phosphorus nor potassium.
作为肥料应用的硫酸铵浓度会更高，但其中只有氮的成分，没有磷或钾。

Gypsum, ammonium hydrogen carbonate and potassium chloride were used as raw materials in this research, to produce potassiumsulfate, potassiumammonium chloride and calcium carbonate.
以石膏、碳酸氢铵和氯化钾为原料，生产硫酸钾、氯化铵钾和碳酸钙，原料综合利用充分，经济效益好。
