Potassium Sulphate Chemical which is usually used in fertilizers which contains both potassium and sulphur. This type of chemical is generally used in industries and other important factories. Potassium sulphate are also used in the agricultural field as a fertilizer for meeting the lack of potassium and sulfur. Potassium sulphate (k2so4) is a non-flammable white crystalline salt that is highly soluble in water. The range is also known as potassium sulphate, also called sulphate of potash, arcanite, or archaically known as potash of sulphur.
