Calcium Ammonium Nitrate (27-0-0 + 12% CaO) represents a scientifically advanced approach to nitrogen fertilization, combining immediate and sustained nitrogen availability with essential calcium nutrition. Engineered for versatility and safety, CAN delivers consistent crop response while actively contributing to soil fertility management. This premium fertilizer addresses the limitations of conventional nitrogen sources through its unique formulation and balanced nutrient profile.

I. Scientific Advantages

• Dual-Form Nitrogen Technology
  CAN contains nitrogen in two complementary forms: 50% as nitrate nitrogen for immediate plant uptake and 50% as ammonium nitrogen for gradual, sustained release. This balanced composition ensures continuous nitrogen availability throughout critical growth stages while minimizing losses through leaching and volatilization.
• Integrated Calcium Nutrition
  With 12% water-soluble calcium oxide, CAN strengthens cell wall development, improves fruit quality, and enhances stress resistance. Calcium plays a vital role in membrane integrity, enzyme activation, and proper nutrient translocation within plants.
• pH-Neutral Soil Impact
  Unlike many nitrogen fertilizers that progressively acidify soils, CAN maintains neutral soil pH through its balanced formulation. This characteristic reduces or eliminates the need for periodic liming applications, preserving long-term soil productivity.
• Enhanced Nitrogen Use Efficiency
  The combination of nitrate and ammonium forms optimizes nitrogen uptake patterns, resulting in 20-30% higher nitrogen use efficiency compared to conventional urea applications.

II. Precision Application Guidelines

Field Crops

• Cereals (Wheat, Corn, Rice): 300-400 kg/ha split between sowing and tillering stages
• Oilseeds (Canola, Sunflower): 250-350 kg/ha with emphasis on early growth phases
• Forage Crops: 200-300 kg/ha following each cutting or grazing cycle

Horticultural Crops

• Vegetables: 150-250 kg/ha with multiple split applications based on crop cycle
• Fruit Trees: 200-400 kg/ha depending on canopy size, age, and yield targets
• Berry Crops: 100-200 kg/ha with particular attention to calcium-sensitive stages

Special Application Conditions

• Cold Soils: Preferred nitrogen source due to immediate nitrate availability when biological activity is limited
