Magnesium Nitrate

Magnesium Nitrate is a water-soluble fertilizers composed of magnesium and nitrogen in nitrate form. It is a highly efficient source of essential nutrients that play a key role in chlorophyll production and overall plant metabolism. As a crystalline white compound, Magnesium Nitrate dissolves rapidly in water, making it ideal for fertigation and foliar applications. It ensures quick nutrient uptake and is widely used across a range of horticultural and field crops to prevent and correct magnesium deficiencies.

Description Magnesium Nitrate is a water-soluble fertilizers composed of magnesium and nitrogen in nitrate form. It is a highly efficient source of essential nutrients that play a key role in chlorophyll production and overall plant metabolism. As a crystalline white compound, Magnesium Nitrate dissolves rapidly in water, making it ideal for fertigation and foliar applications. It ensures quick nutrient uptake and is widely used across a range of horticultural and field crops to prevent and correct magnesium deficiencies. 
Specification
  • Chemical Formula: Mg (NO₃) ₂·6H₂O 
  • Magnesium (Mg): 9.5% minimum 
  • Nitrate Nitrogen (NO₃-N): 11% minimum 
  • Solubility in Water: 100% 
  • Appearance: White crystalline powder 
  • pH (1% solution): 6.0 – 7.5 
Benefits
  1. Enhances Photosynthesis: Magnesium is the central element of chlorophyll. By supplying magnesium in an available form, this fertilizer promotes higher photosynthetic activity, improving plant energy and productivity. 
  2. Boosts Nitrogen Efficiency: The nitrate nitrogen in Magnesium Nitrate enhances root development and protein synthesis, leading to improved plant vigor and yield. 
  3. Quick Correction of Deficiency: It rapidly corrects magnesium deficiencies in crops showing symptoms like interveinal chlorosis, leaf curling, or poor fruit setting. 
  4. Improves Fruit Quality: Magnesium plays a critical role in sugar translocation, thereby enhancing the sweetness, size, and shelf life of fruits like grapes, tomatoes, and citrus. 
  5. Compatible with Other Fertilizers: Magnesium Nitrate blends well with most water-soluble fertilizers, making it suitable for integrated nutrient management plans. 
  6. Reduces Stress: Regular application reduces the impact of abiotic stress such as drought and heat, enhancing plant resilience and productivity. 
  7. No Chloride or Sulphate Content: Unlike other magnesium sources, this product is chloride- and sulphate-free, ensuring no risk of salt buildup or crop toxicity. 
  8. Safe for All Crops: Being highly pure and low in impurities, Magnesium Nitrate is safe for use on sensitive crops including floriculture and exotic vegetables.
Application Magnesium Nitrate can be applied through: 

  • Foliar Spray: Recommended for quick deficiency correction and nutrient support during critical growth stages. 
  • Fertigation: Suitable for drip and sprinkler irrigation systems, ensuring even distribution and efficient root uptake. 

Dosage: 

  • Foliar Spray: 1.0 – 2.0 grams per litre of water, depending on the crop and stage of growth. 
  • Fertigation: 5 – 10 kg per acre per application, depending on soil condition and crop requirement.
    Consult an agronomist for crop-specific recommendations. 
Time
  • Apply Magnesium Nitrate during the vegetative and reproductive stages for best results. 
  • Magnesium Nitrate is ideal at early signs of magnesium deficiency. 
  • During flowering and fruit development to improve quality and yield. 
  • Avoid spraying Magnesium Nitrate during peak sunlight hours; best applied during early morning or late evening. 
Precaution
  • Always use clean water for preparation. 
  • Do not mix Magnesium Nitrate with calcium-containing products in the same tank as it may cause precipitation. 
  • Use protective gear (gloves, mask) during handling and spraying. 
  • Store Magnesium Nitrate away from heat, moisture, and direct sunlight. 
  • Conduct a jar test before mixing with other agrochemicals. 
Shelf Life Magnesium Nitrate has a shelf life of 2 years from the date of manufacture if stored in a cool, dry, and well-ventilated area in the original, unopened packaging. 
Packaging
  • Available in high-quality laminated HDPE or LDPE bags. 
  • Standard pack sizes: 1 kg, 5 kg, 10 kg, 25 kg. 
  • Custom packaging options available on bulk demand.
