Basic Product Attributes

• Chemical Formula: 5Ca(NO₃)₂·NH₄NO₃·10H₂O
• Nutrient Content: N≥26-28% (nitrate N 13-14%, ammonium N 13-14%), CaO≥8-10% (water-soluble)
• Appearance: White/light gray spherical granular, uniform particle size, non-caking
• Key Properties: Highly water-soluble, fast nutrient release, low nitrogen volatilization, stable at room temperature
• Classification: Inorganic compound fertilizer (agrochemicals, fine chemical category)

Core Functions & Nutritional Value

1. Dual nutrient supply: Provides quick-acting nitrate nitrogen (immediately absorbed by crops) and slow-release ammonium nitrogen (sustained supply), matching crop growth rhythm; supplements water-soluble calcium, essential for cell wall formation and fruit development.
2. Soil improvement: Neutral in nature, alleviates soil acidification, improves soil aggregate structure, enhances soil permeability and microbial activity, suitable for saline-alkali and acidic soils.
3. Crop quality enhancement: Prevents calcium deficiency disorders (e.g., blossom-end rot in tomatoes, bitter pit in apples), increases fruit firmness and sugar content, prolongs shelf life, and improves vegetable and fruit commercial quality.
4. Stress resistance improvement: Enhances crop resistance to drought, disease and lodging by promoting root development and cell stability.

Main Applications

Suitable Crops

Application Methods

• Base fertilizer: 20-30kg per mu, mixed with soil before sowing/transplanting, provides basic N-Ca nutrition.
• Top dressing: 10-15kg per mu at seedling stage, flowering stage and fruit expansion stage; suitable for drip/sprinkler irrigation (water-fertilizer integration), dissolves completely without blocking pipelines.
• Foliar fertilizer: Dilute into 0.3-0.5% aqueous solution, spray on leaves in morning/evening, emergency supplementation for calcium deficiency.

Core Product Advantages

1. Fast and sustained fertilizer effect: Dual nitrogen form realizes quick-acting + sustained release, no fertilizer lag, long-lasting nutrient supply.
2. Low nutrient loss: Nitrate nitrogen is less prone to volatilization and leaching, high nitrogen utilization rate (30-40% higher than urea in some crops).
3. Easy to use: Spherical granular with good fluidity, suitable for mechanical spreading; non-caking, easy to store and transport.
4. Wide adaptability: Neutral pH, applicable for all soil types; no chlorine, no harmful ions, safe for chlorine-sensitive crops.
5. Multi-scenario application: Usable for soil application, water-fertilizer integration and foliar spraying, flexible for greenhouse, field and soilless culture.

Storage & Handling Notes

1. Store in a dry, ventilated, cool warehouse; avoid rain, moisture and direct sunlight to prevent deliquescence.
2. Separate from flammable, explosive and alkaline substances during storage and transportation (no chemical reaction, but to ensure safety).
3. Light loading and unloading to prevent particle breakage; the product is non-toxic, but avoid direct contact with eyes for a long time.
4. Shelf life: 24 months under standard storage conditions; no effect on fertilizer effect if slight deliquescence occurs (dissolve and use in time).
