Fertiliser
The dominant use of potassium sulphate is as a fertiliser. K2SO4 does not contain chloride, which can be harmful to some crops. Potassium sulphate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulphate for optimal growth if the soil accumulates chloride from irrigation water.
Air Powered Cleaning
