Multi-K™, Haifa’s potassium nitrate brand, is the basis of a whole line of plain and enriched potassium nitrate products, designed for optimal plant nutrition

 

Potassium nitrate is a source of potassium and nitrogen, two macronutrients (primary nutrients) essential for plant nutrition and growth. Since healthy growth requires large amounts of nitrogen and potassium, these elements have to be added to the soil in order to achieve healthy growth. That's where potassium nitrate fertilizers enter the picture.

 

Multi-K™ advantages:

  • 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 damaging anion is present in the soil solution or in the irrigation water. This makes Multi-K™ a necessity for chloride-sensitive crops.

Multi-KTM - How does it work? watch the video:

 

 

The roles of Potassium (K) in the plant:

  • Necessary for formation of sugars and starch
  • Activator of enzymatic reaction
  • Maintains turgor
  • Regulates opening of leaf stomata
  • Build cell walls

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

 

The advantages of potassium nitrate: synergistic effect
The nitrate facilitates uptake and improves potassium absorption by the plant.
Efficient N source: All the nitrogen in Multi-K™ is the form of Nitrate (NO3-).
