Multi-K™ GG
Greenhouse-grade potassium nitrate, 13.5-0-46.2



Haifa Multi-K GG potassium nitrate (13.5-0-46.2 crystalline) is a fully water-soluble fertilizer and has a highly efficient source of nitrogen and potassium. The fertilizer can be used for Nutrigation and foliar feeding, and recommended for use in all phases of the growing season. Haifa Multi-K GG Fertilizer can be tank-mixed with other fertilizers to meet crop nutritional needs throughout the growth cycle. Haifa Multi-K GG is suitable for preparation of fertilizers blends and for production of liquid fertilizers.

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 Haifa Multi-K GG Fertilizer a necessity for chloride-sensitive crops
Haifa Multi-K GG Fertilizer for hydroponic or greenhouse farms is preferred since it’s highly water soluble, it’s great for foliar application, and it’s used to help boost nitrogen and potassium during the flower and vegetative periods.

The advantages of Haifa Multi-K

  • Fully water-soluble
  • Consists of 100% plant nutrients
  • Free of chloride, sodium and other detrimental elements for plants
  • Safe for plants and humans: has a moderately low pH and low salt index
  • Suitable for the Nutrigation, foliar application and production of fertilizer blends and nutrient solutions.
  • Non-volatile: easy to apply with no nitrogen losses to the atmosphere
  • Wide-range compatibility with all types of fertilizers and agrochemicals

The benefits of Haifa Multi-K

Due to its roles in many plant systems, potassium improves plant durability and improves yield quality:

  • Improved drought resistance
  • Increased winter hardiness
  • Better disease resistance
  • Improved yield quality
  • Longer storage life
  • Necessary for formation of sugars and starch
  • Activator of enzymatic reaction
  • Maintains turgor
  • Regulates opening of leaf stomata
  • Build cell walls



Due to its unique characteristics, Haifa Multi-K GG Fertilizer can be applied through any irrigation system and on any growing medium. Unlike phosphoric acid, Haifa Multi-K GG is moderately acidic. Thus, it does not form corrosion on fertilizer pumps or irrigation equipment.


Haifa Multi-K GG is compatible with all water-soluble fertilizers.

Quantitative Nutrigation:

Each kilogram of Haifa Multi-K GG in the tank provides 462 grams of potassium (K2O) and 135 grams of nitrate-nitrogen (N-N0–3).

Proportional Nutrigation:

The potassium concentration in the irrigation water depends on the quantity of Haifa Multi-K GG in the tank mix, and on the injection ratio.

Foliar Nutrition:

Foliar spraying with Haifa Multi-K GG is effective in supplying potassium whenever a quick response to deficient plants is required. It should be considered as a supplemental method to soil applied potassium. The concentration of Haifa Multi-K solutions can be increased according to leaf age.

TIP: It is advisable to confirm compatibility of your intended spray-mix by preparing a sample of the mixtures at their recommended concentrations in order to rule out the possibility of a detrimental cross reaction. The mixtures should be sprayed onto a small area to test before using it fully. You do this to test whether an adverse effect occurs when foliar spraying your mixture.
