Potassium Sulphate "SOP"

Potassium Sulphate (K2SO4) or Sulphate 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. 
Sulphate 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 Sulphate 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.
