Ammonium Sulfate ((NH₄)₂SO₄) is a specialized nitrogen-sulfur fertilizer designed for balanced nutrient management and soil condition improvement. Different from single nitrogen fertilizers, it provides both nitrogen and sulfur elements, helping crops maintain efficient protein synthesis, enzyme activity, and overall nutrient metabolism.
Manufactured by AOLANSU with dangerous chemicals production certification, this product features stable composition, controlled purity, and reliable batch consistency. Its mildly acidic characteristics make it particularly suitable for alkaline soils and sulfur-deficient farmland, providing an effective solution for professional agricultural production and fertilizer distribution.

The combination of nitrogen and sulfur supports important physiological processes including protein formation, enzyme activation, and nutrient conversion. This balanced supply helps avoid hidden sulfur deficiency problems that may limit crop development.
The acidic characteristics of this fertilizer help regulate alkaline soil conditions, improve nutrient availability, and support a more favorable growing environment for crops cultivated in high-pH farmland.
With excellent water solubility, nutrients can be quickly released after application and absorbed by crops. The product supports rapid nutrient correction while maintaining stable fertilization performance during crop growth.
Uniform crystalline particles provide good storage stability, strong flowability, and resistance to caking. The product is convenient for transportation, automatic spreading equipment, and large-scale agricultural operations.
It can be applied independently or combined with phosphate fertilizers, potassium fertilizers, and organic fertilizers according to soil conditions and crop requirements, supporting customized nutrient management programs.
Ammonium Sulfate ((NH₄)₂SO₄) is widely used for wheat, corn, rice, cotton, and other field crops. It can be applied as base fertilizer before planting, topdressing during growth stages, or seed fertilizer in controlled amounts to support early crop establishment.
Suitable for apples, citrus, pears, leafy vegetables, and other economic crops with high sulfur demand. The fertilizer helps maintain healthy plant metabolism and supports improved crop appearance and quality.
In areas where continuous cultivation has reduced available sulfur levels, the product provides an effective nutrient supplement. It helps improve sulfur availability and supports stronger crop resistance against environmental stress.
Because of its stable chemical properties and high purity, the product is also used in chemical manufacturing, textile processing, electroplating, and pharmaceutical-related industries.
A professional fertilizer distributor in Southeast Asia required a stable source of high-quality nitrogen-sulfur fertilizer for regional agricultural markets. Their previous suppliers experienced inconsistent particle sizes, unstable moisture control, and delayed shipment schedules, which affected warehouse management and customer delivery plans.
After cooperating with AOLANSU, the customer received a continuous supply solution supported by standardized production processes, strict quality inspection, and flexible packaging services. Each batch was tested for nitrogen content, sulfur content, moisture level, particle size, and impurity control before shipment to ensure consistent product performance.
Through stable production capacity and professional export logistics coordination, the distributor improved inventory reliability, reduced procurement risks, and established a long-term supply partnership for agricultural fertilizer distribution in multiple regional markets.
White or grayish-white crystalline particles with uniform color, clean surface, no visible impurities, and consistent 2–4mm particle size.
Solid crystalline particles with moderate hardness and excellent storage stability. The product dissolves quickly in water and forms a clear solution without residue.
Produced through professional neutralization, crystallization, and drying processes. High purity, stable chemical composition, and low impurity levels ensure reliable agricultural and industrial applications.
Uses reinforced woven plastic bags with moisture-proof inner lining and strong sealing performance to prevent moisture absorption, caking, and leakage. Product information, nutrient content, and usage instructions are clearly printed for convenient storage and identification.
Sulfur is an essential secondary nutrient involved in protein synthesis and plant enzyme activity. When soil sulfur availability is insufficient, crops may experience poor growth even when nitrogen supply is adequate. Adding sulfur-containing fertilizer helps maintain balanced plant nutrition.
It is especially recommended for neutral to alkaline soils and farmland with sulfur deficiency. For acidic soils, application rates should be adjusted according to soil testing results and crop requirements.
