Potassium Sulfate fertilizers

Sulfate of Potash: The Gentle Fertilizer

Potassium Sulfate (K2SO4) or Sulfate of Potash (SOP), is the world's most popular low-chloride fertilizer. Combining Potassium (50% K2O) and Sulphur (18%) SOP offers a high concentration of nutrients readily available to plants.
Sulfate of Potash has a very low salinity index making it the preferred potash fertilizer in areas at risk from soil salinity.

SOP improves crop yield and quality, making plants more resistant to drought, frost, insects and disease.
Not only does Potassium Sulfate improve the crop's nutritional value, taste and appearance but also its resistance to deterioration during transport and storage, and its suitability for industrial processing.

Tessenderlo Group produces the full range of sulfate of Potash grades; standard, granular (GranuPotasse®) and fully soluble (SoluPotasse®). In 2011, Tessenderlo Group launched a specially developed sulfate of potash fertilizer (SOP), suitable for foliar applications: K-Leaf®.
