Magnesium Nitrate fertilizer for healthy crops
magnesium nitrate fertilizer provides plants with readily-available magnesium, which is essential for their healthy growth
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 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 and foliar spray and assists in generation of energy. Magnesium deficiency retards plants development, resulting in decreased yields and poor quality.
Deficiency symptoms
Magnesium deficiency is manifested by yellow bands between leaf veins. The symptoms show first on older leaves, and move towards young leaves as deficiency worsens. In severe cases, necrosis may appear.
is a superior source of magnesium
Magnesium nitrate is superior to magnesium sulfate fertilizers. It possesses higher nutritional value and better physical properties that make it more convenient for handling and application.
Plant nutritional value
Plants absorb the magnesium from more readily, due to the interaction between the magnesium and the nitrate anion. is up to three-fold more effective than magnesium sulfate in preventing and curing magnesium deficiencies, and therefor enables considerably lower
application rates.

pH and EC
It is slightly acidic, which improves its absorption by leaf surface when sprayed, and enables tank-mixing with chelated nutrients and pesticides. The electrical conductivity (EC) it solution is low, compared to other fertilizers.

Physical and chemical properties
It is fully soluble in water. It is approximately ten-fold more soluble than Magnesium Sulfate:
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.Nutrigation
It is ideal for Nutrigation of crops in both soil and soilless media. Pure and highly soluble, It is safe for use with all types of irrigation equipment. It is compatible with all water-soluble fertilizers, except concentrated phosphate solutions.
It unlike magnesium sulfate, can be used with water of poor quality, hence recommended when the irrigation water contains high levels of sulfates or salts. In most irrigation practices, magnesium concentration in the water should range between 20-60 ppm.
The following table shows stock-solution levels and injection ratios needed to obtain specified magnesium concentrations in the irrigation water.
The exact fertilization program should be determined according to the specific crop needs, soil and water conditions, and the grower’s experience. For best results, follow the recommendation of a local crop consultant.Note: data refer to magnesium (Mg) levels in the irrigation water, not to magnesium oxide (MgO).
Nutrigation in soilless media: For most crops, recommended magnesium concentration in the nutrient solution is 50-70 ppm MgO (30-40 ppm Mg). The magnesium level in the irrigation water should be taken into account. When theTwo-Tank method is employed, dissolve It in the tank that does not contain phosphorus (P).
The given recommendations should be regarded as a general guide only.
for foliar applications: Foliar spray is an efficient tool to supplement and to enrich plant nutrition. When absorption of nutrients from the soil is disturbed, foliar application of It provides the magnesium needed for normal development of crops. When prompt correction of magnesium deficiency is required, foliar application is recommended, as uptake of magnesium by the leaves is very fast.
Preparation of tank-mix: Dissolve It in a small amount of water and add to the spray tank. When applying with crop protecting agents, addition of wetting agent is not necessary. To ensure compatibility of tank-mix components, perform a small-scale test prior to actual application.
Foliar spray: To verify safety of suggested rates under local conditions and for specific varieties, it is recommended to spray on a few branches or plants. After 3-4 days check the tested plot for scorching symptoms.
