Calcium Magnesium Nitrate (CMN) is a highly efficient and versatile fertilizer used in agriculture, horticulture, and other industrial applications.
-
Calcium Magnesium Nitrate Overview
Chemical Composition: CMN is a granular or crystalline fertilizer composed of calcium (Ca), magnesium (Mg), and nitrate (NO₃⁻).
Formulation: Commonly available as a mixture of Calcium Nitrate (Ca(NO₃)₂) and Magnesium Nitrate (Mg(NO₃)₂) in various ratios.
Appearance: Typically white or off-white in color, soluble in water, and suitable for soil and foliar applications.
-
Key Benefits
Nutrient Supply: Provides essential nutrients—calcium and magnesium—alongside nitrate nitrogen, promoting healthy plant growth.
Improved Soil Structure: Enhances soil structure by providing calcium, which reduces soil compaction and improves water infiltration.
Rapid Nutrient Uptake: Nitrate form ensures quick absorption by plant roots, leading to faster growth and development.
Increased Yield: Promotes higher crop yields due to the balanced supply of key nutrients.
Stress Resistance: Improves plant resistance to environmental stresses, such as drought and diseases.

Applications of Calcium Magnesium Nitrate
Agriculture: Suitable for various crops, including fruits, vegetables, cereals, and cash crops. Applied via broadcasting, fertigation, or foliar spraying.
Horticulture: Used in greenhouses and nurseries for ornamental plants, flowers, and vegetables.
Industrial: Employed in soil conditioning and as a raw material in the production of other calcium and magnesium compounds.
-
Usage Recommendations
Dosage: Varies depending on crop type, growth stage, and soil conditions. Typically, 200-500 kg per hectare.
Application Timing: Best applied during the early stages of plant growth or during periods of high nutrient demand.
Compatibility: Can be mixed with most fertilizers and pesticides. However, avoid mixing with phosphates or sulfates to prevent precipitation.
-
Handling and Storage
Storage: Store in a cool, dry place, away from moisture and direct sunlight. Keep the product tightly sealed when not in use.
Safety Precautions: Wear protective gloves and eyewear when handling. Avoid inhalation of dust and contact with skin.
Shelf Life: Typically stable for up to two years when stored under proper conditions.
-
Environmental Impact
Eco-Friendly: CMN is environmentally friendly, as it reduces the risk of soil acidification and nutrient leaching.
Sustainability: Supports sustainable agriculture practices by improving soil health and reducing the need for chemical inputs.
CMN is a vital fertilizer that plays a crucial role in modern agriculture by improving plant health, increasing yields, and promoting sustainable farming practices.
