Potassium Sulfate

Potassium Sulfate is an inorganic salt with the formula: K₂SO₄. It occurs naturally as the rare mineral arcanite and finds use as a fertilizer, in glass manufacturing, and as a chemical precursor to other potassium compounds.

Agriculture
Aside from being a source of both potassium and sulfur, potassium sulfate is a choice fertilizer ingredient for soils with either a chlorine accumulation problems or for plants that do not agree with chlorine ions.

Additional Notes:
* MgSO₄ *H₂O combined with KCl(aq) can produce potassium sulfate, K₂SO₄
