What Is Sulphate of Potash (SOP) Fertilizer from Vietnam?

Sulphate of Potash (SOP), chemically known as Potassium Sulphate (K₂SO₄), is a premium potassium fertilizer widely used for chloride‑sensitive crops and high‑value horticulture.

Compared with MOP (Muriate of Potash), SOP provides:

  • High potassium (K₂O)
  • Essential sulfur (S)
  • Low chloride levels

This makes SOP ideal for crops requiring high nutrient efficiency and low salinity stress.
