Product: High Solubility CMN-Calcium Magnesium Nitrate Fertilizer for Agriculture
Water-Soluble Neutral pH Calcium Magnesium Nitrate offers a wide range of benefits for crop cultivation. It enhances chlorophyll content and supports photosynthesis, promotes nucleic acid conversion and protein synthesis, and improves the uptake of essential nutrients such as nitrogen, phosphorus, and potassium. By addressing calcium deficiencies, it helps prevent common physiological disorders in crops.
This fertilizer also strengthens cell walls, stimulates chlorophyll production, and encourages the formation of sugars and carbohydrates, leading to higher quality and longer-lasting fruits and vegetables. In addition, it improves fruit firmness, enhances color, increases yield, and elevates the overall grade of crops, while boosting grain production and overall crop quality.

Effects of Magnesium Deficiency in Plants
- Interveinal Chlorosis: Leaves turn yellow while the veins remain green, often starting with older leaves.
- Leaf Margin Changes: Leaf edges may develop reddish-brown or purple discoloration.
- Leaf Necrosis: Prolonged deficiency can cause leaves, stems, and other plant parts to wilt and die.
- Impaired Carbon and Nitrogen Metabolism: Magnesium deficiency negatively affects photosynthesis and nutrient metabolism, reducing the plant’s ability to process carbon and nitrogen efficiently.
- Stunted Growth and Plant Death: If not corrected, magnesium deficiency can slow overall growth and may eventually lead to plant death.
Why Our Calcium Magnesium Nitrate Stands Out
- Premium Quality & Fully Soluble: 100% water-soluble with no residue, perfect for fertigation and foliar applications.
- Complete Nutrition in One: Supplies nitrogen, calcium, and magnesium simultaneously to maximize crop growth and efficiency.
- Healthier Plants & Superior Yield: Calcium strengthens cell walls while magnesium boosts photosynthesis for stronger, more productive crops.
- Flexible Use: Suitable for soil application, irrigation systems, and foliar spraying.
- Soil-Friendly & Sustainable: Neutral pH helps improve soil structure and reduces acidification, supporting long-term soil health.

Application & Recommended Dosage
Field Crops (corn, rice, wheat): 200–400 kg per hectare
Vegetables (tomato, cucumber, leafy greens): 300–600 kg per hectare
Fruit Trees (citrus, apple, banana, grape): 0.5–2 kg per tree
Foliar Spray: 3–5 kg per 1000 L water
Note: Dosage may vary depending on crop type, soil conditions, and growth stage.
Suitable Crops
Fruits 🍊: Citrus, grapes, apples, bananas, melons, strawberries
Vegetables 🥦: Tomatoes, cucumbers, peppers, potatoes, lettuce
Field Crops 🌾: Corn, wheat, rice, soybean, sugarcane

Usage Recommendations
Base Fertilization (Soil Application):
Apply evenly to the soil before planting or during crop growth to improve soil nutrition.
Fertigation (Drip Irrigation / Sprinkler Irrigation):
Dissolve in water and apply through irrigation systems for efficient nutrient supply.
Foliar Spray:
Use diluted solution (0.3%–0.5%) for direct absorption by leaves, especially during critical growth stages.
⚠️ Do not mix with phosphate or sulfate fertilizers in concentrated solutions to avoid precipitation.
Packaging & Storage
