SoluPotasse®

SoluPotasse® is the original, and best-in-class, water-soluble grade of sulfate of potash (SOP), providing a highly soluble form of potassium and sulfur, in the sulfate form. It contains 51.5% potash (K2O w/w) and 18.7% sulfur (S w/w) and can be used for fertigation in a wide variety of crops.

Benefits

  • Dissolves rapidly and completely leaving no residues
  • Lower pH solution improves the availability to the plant of phosphorus, iron and most other micronutrients and helps to prevent drippers from clogging
  • Extremely low salt index
  • Improves crop yield and quality
  • Increases crops’ resistance to damage during transport and storage
  • Virtually no chloride and free of nitrates
  • Helps boost the crop’s resistance to stress

SoluPotasse® may be applied by drip, micro-sprinkler, sprinkler, flood irrigation or pivot system. It may be blended with most other fertilizers, except that containing calcium. SoluPotasse® helps growers produce high quality crops with maximum export value, whilst protecting the environment.
