What Is Potassium Magnesium Sulphate (Schoenite)?
Potassium Magnesium Sulphate, commonly referred to as Schoenite, is a mineral fertilizer that provides potassium, magnesium and sulphur.
The mineral is commonly associated with the chemical formula:
K₂Mg(SO₄)₂·6H₂O
It provides a combination of essential crop nutrients in one fertilizer product:
- Potassium supports important plant physiological processes.
- Magnesium is an essential component of chlorophyll and is involved in photosynthetic processes.
- Sulphur is an important nutrient involved in plant growth and metabolism.
Potassium Magnesium Sulphate is commonly used in agricultural soils, fertilizer blends and crop nutrition programs where potassium, magnesium and sulphur are required.
