Potassium sulphate (UK) or Potassium sulfate (US), also called sulphate of potash (SOP), arcanite, or archaically potash of sulfur, is the inorganic compound with formula K2SO4, a white water-soluble solid. It is commonly used in fertilizers, providing both potassium and sulfur.
Usage of Potassium Sulphate:
Fertilizers, Manufacture of glass and other.
The dominant use of potassium sulfate is as a fertilizer. Potassium sulphate does not contain chloride, which can be harmful to some crops. Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water.
