Potassium sulfate is an inorganic salt.It is mainly used as potassium fertilizer in agriculture.And It also is used as the raw material of BLENDING NPK.

Potassium Sulfate is a natural mineral containing 52 percent soluble potash and 18 percent sulfur; it also contains trace amounts of calcium and magnesium. Crops can use as much as 250 of Potassium Sulfate per acre per year, making Potassium first runner up in abundance needed for plants to thrive. You can apply it as a supplement or other natural blended materials to aid in soil deficiencies.

Usage
1. The dominant use of potassium sulfate is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops.
2. 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.
3. The crude salt is also used occasionally in the manufacture of glass. Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast overpressure.
4. It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.
5. Potassium sulfate can also be used in pyrotechnics to generate a purple flame.

Specification:

1.Providing potassium to crops sensitive to chloride and salt
2.Contains a low salt index helping to avoid the plant taking up excess water
3.Mixes well with all other fertilizers
