The dominant use of E515 is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops. E515 is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require E515 for optimal growth if the soil accumulates chloride from irrigation water.
The crude salt is also used occasionally in the manufacture of glass. E515 is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback, and blast overpressure.
It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.
E515 can also be used in pyrotechnics in combination with potassium nitrate to generate a purple flame.
