This single element fertilizer is designed to supply potassium in different plants in a timely manner. Potassium acts as an activator of plant enzymes and has a significant role in crop quality and plant resistance against all types of biological stresses.

Applications and usage

  • It is suitable in situations where the plant cannot absorb potassium in the soil (hot and dry conditions, high humidity and sandy soil).
  • Application of this fertilizer during cold and freezing weather causes vegetable juices to concentrate which prevents frostbiting.
  • Application rates are for guidance only. Actual rates will vary with local growing conditions, soil analysis and plant’s age.
  • It is compatible with most types of fertilizers and pesticides.
  • Avoid mixing this fertilizer with acidic compounds such as potassium sulfate, urea phosphate and calcium-containing compounds.
