AOLANSU Ammonium Sulfate Blended Fertilizer is a granular nitrogen and sulfur fertilizer designed to provide crops with balanced ammonium nitrogen and sulfur nutrition. By combining these two essential nutrients, it supports healthy plant growth, improves nutrient utilization and helps maintain crop quality during different growth stages.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., a professional fertilizer manufacturer in China, this fertilizer is produced through precise blending technology to ensure uniform nutrient distribution, stable granule quality and reliable application performance. It is widely used in grain crops, vegetables, fruit trees and sulfur-demanding crops worldwide.
Nitrogen is one of the most important nutrients required by crops. It participates in chlorophyll formation, leaf development and overall plant growth. However, nitrogen efficiency can be affected by soil conditions, especially in areas with nutrient imbalance or high nitrogen loss.
Sulfur plays an essential role in protein synthesis, enzyme activity and plant metabolism. Crops with high sulfur demand may show reduced growth performance when sulfur availability is insufficient.
AOLANSU Ammonium Sulfate Blended Fertilizer supplies nitrogen and sulfur together, helping farmers achieve more balanced nutrient management compared with nitrogen-only fertilizers.
The combination of ammonium nitrogen and sulfur provides two complementary nutrients in one fertilizer product. Nitrogen supports vegetative growth, while sulfur contributes to protein formation and crop quality development.
Ammonium sulfate fertilizers have mildly acidic characteristics, making them commonly used in alkaline soil conditions where sulfur supplementation is required. Proper application can improve nutrient availability and support better soil nutrient management.
The fertilizer granules are produced with controlled particle size and good physical stability. The uniform shape provides excellent flowability, making the product suitable for manual spreading, mechanical fertilization and large-scale agricultural operations.
AOLANSU provides low-chloride fertilizer solutions suitable for crops sensitive to chloride accumulation, including certain vegetables, fruit trees and specialty crops.
AOLANSU follows a controlled production process including raw material inspection, formula blending, granule screening and finished product testing. Each production stage is monitored to maintain consistent nutrient content and stable physical properties.
The fertilizer granules are carefully processed to achieve good hardness, low dust generation and resistance to caking during transportation and storage.
Different crops have different sulfur requirements. AOLANSU Ammonium Sulfate Blended Fertilizer is commonly applied in the following agricultural areas:
Ammonium Sulfate Blended Fertilizer can be applied before planting and incorporated into soil. This method provides a stable nutrient foundation for early crop development and supports root establishment.
During important growth stages such as tillering, flowering or fruit expansion, the fertilizer can be applied as top dressing to supplement nitrogen and sulfur requirements according to crop conditions.
The uniform granular structure makes the product suitable for large-scale mechanical spreading. Good flowability helps improve application accuracy and reduce fertilizer waste during field operations.
Ammonium Sulfate Blended Fertilizer can be combined with other fertilizer products according to soil nutrient conditions and crop requirements. Customized blending solutions are available for agricultural distributors and professional growers.

As a China fertilizer manufacturer, AOLANSU supplies ammonium sulfate fertilizer solutions for distributors, importers and agricultural businesses in Southeast Asia, Africa, South America and other international markets.
AOLANSU applies strict quality management throughout the fertilizer manufacturing process to ensure stable product performance for agricultural applications.
Before production, raw materials are inspected for nutrient content, moisture level and physical characteristics. Only qualified materials enter the blending process.
The production team controls the blending ratio and mixing uniformity to ensure that nitrogen and sulfur nutrients are evenly distributed throughout the fertilizer granules.
Each production batch is tested for nitrogen content, sulfur content, particle size, moisture and appearance. Quality documents such as COA and MSDS can be provided according to customer requirements.
In Southeast Asian rice-growing areas, farmers commonly face challenges such as nutrient imbalance and sulfur deficiency caused by intensive cultivation. AOLANSU Ammonium Sulfate Blended Fertilizer was introduced into local fertilization programs to provide additional sulfur nutrition together with ammonium nitrogen.
During field observation, growers reported improved plant color, stronger crop growth and more balanced nutrient management compared with previous fertilization practices. The application experience demonstrated the suitability of nitrogen-sulfur fertilizer solutions for rice production in areas requiring sulfur supplementation.
For vegetable cultivation, especially sulfur-demanding crops such as garlic and onion, ammonium sulfate-based fertilizer solutions are commonly used to supplement sulfur nutrition. Proper application helps support healthy plant development and maintain crop quality.
Ammonium Sulfate Blended Fertilizer is mainly used to provide nitrogen and sulfur nutrients for agricultural crops. It is suitable for grain crops, vegetables, fruit trees and crops with higher sulfur requirements.
The main difference is nutrient composition. Ammonium sulfate provides both nitrogen and sulfur, while urea mainly supplies nitrogen. For sulfur-deficient soils or sulfur-demanding crops, ammonium sulfate can provide additional sulfur nutrition.
Yes. Due to its acidic characteristics, ammonium sulfate fertilizer is commonly used in alkaline soil conditions where sulfur supplementation and improved nutrient availability are required.
Crops such as garlic, onion, wheat, rapeseed, tea, vegetables and some fruit crops may have higher sulfur requirements. The suitable application rate depends on crop type, soil condition and nutrient management plan.
Yes. AOLANSU provides customized fertilizer solutions according to crop requirements, soil conditions, nutrient ratios and customer market needs.
Standard packaging includes 25kg and 50kg woven bags with PE liners. Customized packaging, labels and bulk packing solutions are available for distributors and importers.
Yes. Sample orders can be arranged for customers who need to evaluate product quality and application performance before large-scale purchasing.
