Production Process & Features
ASN fertilizer is manufactured through high-tower melt granulation, combining premium ammonium sulfate and ammonium nitrate. This technology produces spherical granules with smooth surfaces and excellent water solubility (>99%), enabling rapid nitrogen release within 24 hours and sustained supply for 30-50 days. Containing over 12.5% sulfur—a critical element for enzyme activation and protein synthesis—it achieves 70% nitrogen use efficiency (compared to 35-40% for urea) and is biuret-free, eliminating seedling burn risks. The balanced 1:1 ratio of ammonium (NH₄⁺) and nitrate (NO₃⁻) nitrogen enhances crop stress resistance and adapts to diverse soil types.

Core Advantages & Applications
Urea Replacement: ASN fully replaces urea, increasing yield by 8-12% in rice-wheat rotations while doubling nitrogen efficiency.

Compound Fertilizer Enhancement: As a core ingredient, ASN boosts nitrate nitrogen content by 15-20%, optimizing NPK synergy, especially for fruits and vegetables.

Direct Application Flexibility: Suitable for basal dressing, topdressing, and drip irrigation, it significantly benefits sulfur-deficient soils (e.g., sandy or low-organic soils), improving crop quality.
Global Trade Efficiency: Certified with ISO 14001 and exempt from CIQ inspection, it ensures fast logistics (7-15 days delivery), reducing supply chain costs.

Scientific Validation & Sustainability
Field trials verify that ASN reduces ammonia volatilization by 30% and nitrogen leaching by 25% in maize cultivation, while maintaining stable soil pH to counter urea-induced acidification. Its high sulfur content suppresses soil-borne diseases, cutting pesticide use by 10-15%. ASN is widely adopted in Southeast Asia and South America.
