AOLANSU Ammonium Sulfate Blended Fertilizer is developed for agricultural programs where both nitrogen and sulfur need to be supplied through one granular product. Unlike a nitrogen-only fertilizer program, this formulation combines ammonium nitrogen with sulfur to support crop nutrition while simplifying fertilizer sourcing and field application. It is suitable for fertilizer distributors, importers, commercial farms, agricultural cooperatives, and crop production projects.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., the product is produced with controlled blending and granulation processes to achieve consistent nutrient distribution, suitable particle size, good flowability, and reliable storage performance. AOLANSU provides standard and customized nitrogen-sulfur formulations for different crops, soil conditions, application methods, and regional fertilizer markets.
As part of its compliance and business capability, AOLANSU holds a Hazardous Chemicals Business License for applicable business activities and can provide relevant product documentation for qualified international buyers.

Nitrogen and sulfur perform different but complementary functions in crop nutrition. Nitrogen is required for vegetative growth, chlorophyll formation, and protein production, while sulfur participates in amino acid synthesis, enzyme activity, and plant metabolism. When soil sulfur availability is insufficient, supplying nitrogen alone may not provide a complete nutrient management solution.
This nitrogen-sulfur combination allows growers to address two nutrient requirements within one fertilizer program. It is particularly useful for crops with relatively high sulfur demand and agricultural areas where repeated cropping or intensive cultivation has reduced available sulfur in the soil.
The product provides ammonium nitrogen together with sulfur, allowing farmers to supplement two important nutrients through a single granular fertilizer. This can simplify fertilizer planning compared with purchasing separate nitrogen and sulfur sources.
Fields with low sulfur availability may require additional sulfur fertilization to maintain balanced crop nutrition. The product can be incorporated into fertilizer programs where soil testing or agronomic assessment indicates a need for sulfur supplementation.
Ammonium sulfate-based fertilizers have acidifying characteristics in soil after nitrification. They are therefore commonly considered for agricultural areas with alkaline soil conditions. Application should be based on soil pH, crop requirements, and local agronomic recommendations rather than using the product as a universal pH correction material.
Controlled granulation produces particles with consistent size and good flow characteristics. This makes the fertilizer suitable for fertilizer spreaders, mechanized field operations, and large-scale agricultural applications where uniform distribution is important.
For crops and farming programs where chloride input needs to be controlled, AOLANSU can provide low-chloride fertilizer solutions. Buyers can discuss specific chloride requirements with the sales team when requesting a quotation.
Wheat, rice, corn and other cereal crops can use nitrogen-sulfur fertilizer programs when both nutrients are required. The nitrogen component supports vegetative development, while sulfur contributes to protein formation and overall nutrient balance.
Garlic, onion, cabbage, leafy vegetables and other crops with relatively high sulfur requirements can benefit from appropriate sulfur supplementation. Application timing should be coordinated with soil fertility and crop growth stage.
Rapeseed and other oil crops have significant nutrient requirements during vegetative and reproductive development. A nitrogen-sulfur fertilizer program can be incorporated into crop nutrition plans where sulfur availability is limited.
Citrus, grapes, tea, cotton and other commercial crops can be included in nitrogen-sulfur fertilization programs when soil and crop conditions indicate a need. The application rate should be determined according to crop type, soil test results, and local cultivation practices.
The product can be incorporated into soil before planting or during field preparation. This provides nitrogen and sulfur near the beginning of the crop growth cycle and can form part of a broader basal nutrient management program.
Top dressing can be used during periods when crop nitrogen demand increases, such as tillering in cereals or active vegetative development in vegetables. Application timing should be adjusted according to crop development and soil nutrient availability.
The granular structure provides good flowability through common fertilizer spreading equipment. Uniform particles can help improve distribution accuracy and reduce problems associated with excessive powder during large-scale field operations.
For professional agricultural buyers, AOLANSU can discuss customized nitrogen-sulfur ratios and other formulation requirements. Customized solutions can be developed according to crop nutrition programs, soil conditions, application methods, and market specifications.

Raw materials are checked before entering production. Key indicators such as nutrient composition, moisture, particle characteristics, and relevant quality parameters are monitored to maintain stable production inputs.
AOLANSU controls the formulation ratio and blending uniformity during production. Granulation and screening processes help achieve consistent particle characteristics, good handling performance, and stable physical quality.
Finished batches are inspected for nitrogen content, sulfur content, moisture, particle size, appearance, and other applicable quality indicators. COA and MSDS can be provided according to customer and market requirements.
The fertilizer should be stored in a cool, dry, and well-ventilated warehouse. Packages should be protected from rain, excessive humidity, direct sunlight, and contamination. After opening, unused fertilizer should be properly resealed to help maintain product quality.
Standard packaging includes 25 kg and 50 kg PP woven bags with PE liners, while jumbo bags are available for larger-volume agricultural distribution. AOLANSU can also provide customized labels, packaging specifications, and OEM solutions for qualified distributor and importer orders.
With factory-based production and export support, AOLANSU serves agricultural fertilizer buyers in Southeast Asia, Africa, South America, the Middle East, and other international markets. Trial orders can be arranged before regular bulk procurement.
For distributors and importers, sourcing a nitrogen-sulfur fertilizer involves more than comparing the price per ton. Formula consistency, granule quality, packaging, documentation, order flexibility, and delivery reliability all affect the overall procurement cost.
AOLANSU provides standard specifications together with customized formulation and packaging options. Buyers can request product samples, technical documents, COA, MSDS, packaging specifications, and quotation information according to their purchasing requirements.
It is mainly used to supply nitrogen and sulfur to agricultural crops. It is suitable for cereals, vegetables, oil crops, fruit trees, tea, cotton, and other crops where both nutrients are required.
The main difference is nutrient composition. Ammonium sulfate supplies both nitrogen and sulfur, while urea primarily supplies nitrogen. If soil sulfur is insufficient, a separate sulfur fertilizer may be required when using urea.
Ammonium sulfate-based fertilizers have acidifying characteristics and are commonly considered for alkaline agricultural soils. However, application should be based on soil testing and an appropriate nutrient management plan.
Garlic, onion, rapeseed, cabbage, some leafy vegetables, wheat, tea, and several other crops may have relatively high sulfur requirements. Actual fertilizer demand depends on soil sulfur availability and crop production conditions.
