In large-scale modern agriculture and industrial applications, securing a stable source of high-quality nutrients is paramount to success. As a leading ammonium sulfate supplier, XY Fertilizer is dedicated to delivering top-tier crystalline and granular ammonium sulfate (AmS) to international importers, regional distributors, and agricultural enterprises worldwide. Whether you are blending customized fertilizers or applying nutrients directly to high-yield crops, our products ensure optimal performance and an exceptional return on investment (ROI).
Navigating the global chemical and fertilizer market requires a supplier who understands the delicate balance between competitive pricing, uncompromised quality, and supply chain security. Commercial buyers choose XY Fertilizer for several distinctive advantages:
Dual-Nutrient Efficiency: Our ammonium sulfate delivers highly available Nitrogen ($21\%\ N$ in ammonium form) and readily soluble Sulfur ($24\%\ S$). This combination is ideal for alkaline soils and sulfur-deficient crops, driving robust plant growth and significantly enhancing crop quality.
Superior Physical Properties: Our granular grades feature excellent hardness, uniform particle size distribution (typically 2-4mm), and an anti-caking treatment. This guarantees seamless mechanical application and flawless performance in bulk blending ($BB$) fertilizer factories without dust generation.
Exceptional Chemical Purity: Processed under strict industrial standards, our crystalline grade features high solubility and minimal heavy metal impurities, making it highly versatile for both agricultural fertigation and specific industrial water-treatment processes.
Every shipment undergoes rigorous laboratory testing to comply with international quality certifications. Below are the standard specifications for our bulk wholesale supply:
| Technical Parameters | Crystalline Grade | Granular Grade |
| Nitrogen Content (N) | ≥ 21.0% | ≥ 21.0% |
| Sulfur Content (S) | ≥ 24.0% | ≥ 24.0% |
| Moisture | ≤ 0.5% | ≤ 1.0% |
| Size Guide | Fine Crystals | 2.0mm - 4.0mm (90% min) |
| Free Acid ($H_2SO_4$) | ≤ 0.05% | ≤ 0.1% |
