Potassium sulphate (K2SO4), also called sulphate of potash or SOP, supplies two plant nutrients in one product: potassium and sulphur. It is the preferred potash for chloride-sensitive crops such as tobacco, fruits, vegetables, potatoes, tea, coffee and grapes, and for saline soils where muriate of potash (MOP) can harm yield and quality.
Our potassium sulphate is produced by the Mannheim process at a manufacturing facility in Taiwan, and shipped directly from the plant.
