  • 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.
