High Purity Ammonium Sulfate Fertilizer
A high-purity nitrogen-sulfur fertilizer specifically designed for agricultural applications. This premium-grade ammonium sulfate (21% N, 24% S) is derived as a byproduct from caprolactam production, ensuring exceptional quality with minimal heavy metal content. Its crystalline form provides excellent storage and handling properties. The balanced N-S ratio promotes optimal plant growth, particularly benefiting sulfur-deficient crops like cruciferous vegetables and cereals. With low hygroscopicity and high solubility, it's suitable for various application methods including direct soil application and fertigation. This eco-friendly fertilizer helps maintain soil pH while delivering essential nutrients for improved crop yield and quality.
- Product Description
Advantages of Caprolactam-Grade Ammonium Sulfate Fertilizer
Exceptional Purity
- ≥99.5% chemical purity (vs. 95-98% in standard grades)
- Ultra-low heavy metal content:
• Lead (Pb) <0.5 ppm
• Cadmium (Cd) <0.1 ppm
• Arsenic (As) <0.5 ppm
Benefit: Meets strict EU/Japanese fertilizer regulations and safe for sensitive crops
Premium Nutrient Profile
- 21% nitrogen (as readily available ammonium)
- 24% sulfur (as plant-accessible sulfate)
- Optimized N ratio (1:1.14) for balanced nutrition
Benefit: Corrects sulfur deficiency effectively while reducing nitrogen losses
Superior Physical Properties
- Uniform crystalline structure (0.5-3.0mm granules)
- Minimal moisture absorption (<0.2% water content)
- Anti-caking properties
Benefit: Excellent flowability for precision application and storage stability
Enhanced Crop Performance
- Low chloride content (<50 ppm) benefits chloride-sensitive crops
- Acidifying effect neutralizes alkaline soils (pH 5-6)
- Promotes oil synthesis in oilseeds & protein formation in grains
Benefit: Increases yield and quality in cruciferous vegetables, cereals, and orchards
Environmental Sustainability
- Byproduct utilization from nylon production
- Zero VOC emissions during application
- Fully water-soluble (75g/100ml) for fertigation efficiency
Benefit: Reduces environmental footprint while preventing soil salinization
Operational Efficiency
- Compatible with all application methods (broadcast, fertigation, foliar)
- No impurities clog irrigation systems
- Reduced frequency of application needed compared to standard AS
Benefit: Lowers operational costs through optimized nutrient delivery
