Multi-K®, Haifa’s potassium nitrate brand, is the base of a whole line of plain and enriched potassium nitrate products.

  • Fully water soluble.
  • Consists of 100% plant macronutrients.
  • Free of chloride, sodium and other detrimental elements for plants.
  • Efficiently absorbed by plants.
  • Wide-range compatibility with all types of fertilizers and agrochemicals.
  • Non-volatile; easy to apply with no nitrogen losses to the atmosphere.

The presence of nitrate in Multi-K® enables the plant to minimize its uptake of chloride, whenever this deleterious anion is present in the soil solution or in the irrigation water. This makes Multi-K® a necessity for chloride-sensitive crops.


Multi-K consists of a number of products under the following categories:


  • Crystalline products (Multi-K Classic)
  • Enriched products (Multi-npK, Multi-K mg, Multi-K Zn, Multi-K S, Multi-K B, Multi-K ME)
  • Special grades (Multi-K GG, Multi-K pHast, Multi-K Top)
  • Multi-K prills (Multi-K Prills, Multi-npK Prills, Multi-K Mg Prills)
