Magnesium Nitrate Water Soluble Hydroponic Fertilizer


Magnisal™ magnesium nitrate fertilizer provides plants with readily-available magnesium, which is essential for their healthy growth.

The nitrate in Magnisal™ facilitates the uptake of magnesium by the plant, thus improving its efficiency. It also enriches plant nutrition with readily available, easily absorbed nitrogen.

Magnesium is essential for the plant

Magnesium is a vital nutrient for healthy plant growth. It is a key component of the chlorophyll molecule, hence essential for photosynthesis and formation of carbohydrates. Magnesium is involved in enzymatic reactions and assists in generation of energy. Magnesium deficiency retards plants development, resulting in decreased yields and poor quality.

The benefits of Magnisal™ - magnesium nitrate fertilizer

  • Prevents and cures magnesium deficiencies
  • Consists of 100% plants nutrients
  • Free of chloride, sodium and other detrimental elements
  • Dissolves quickly and completely in water
  • Ideal for efficient applications by fertigation,hydroponics and foliar spray


Nutrigation™ with Magnisal™

Nutrigation™ (fertigation), delivery of pure plant nutrients through the irrigation system, is a highly efficient application method, enabling full control over rates, composition, timing and placement of plant nutrition.

Magnisal™ is ideal for Nutrigation™ of crops in both soil and soilless media. Pure and highly soluble, Magnisal™ is safe for use with all types of irrigation equipment. It is compatible with all water-soluble fertilizers, except concentrated phosphate solutions.

Magnisal™, unlike magnesium sulfate, can be used with water of poor quality, hence recommended when the irrigtion water contains high levels of sulfates or salts. In most irrigation practices, magnesium concentration in the water should range between 20-60 ppm.


One gram of Magnisal magnesium nitrate in one gallon of water yields about 29ppm Nitrate nitrogen and 25ppm Magnesium. Magnisal magnesium nitrate is compatible with calcium fertilizers and may be used in concentrated cal-mag fertilizer formulations.
