Agricultural Ammonium Sulfate

AOLANSU Agricultural Ammonium Sulfate is a widely used inorganic compound fertilizer (containing nitrogen and sulfur) in modern agricultural cultivation. Produced in China using high-quality raw materials and a mature crystallization process, this product is manufactured under standardized conditions; it contains no harmful additives and is safe and reliable for agricultural use.

- Appearance: White crystalline solid; odorless, non-toxic, and harmless.

- Purity: ≥ 99.0%; uniform granules with excellent flowability.

- Nutrients: Nitrogen ≥ 21.0%, Sulfur ≥ 23.5%.

- Solubility: Fully water-soluble; rapidly absorbed by crops.

- Product Stability: Low hygroscopicity (moisture absorption) and resistance to caking, ensuring convenient storage and application.

Key Advantages:

1. Balanced Supply of Dual Nutrients (Nitrogen & Sulfur)

Nitrogen is a core constituent of crop proteins, chlorophyll, and enzymes, facilitating leaf growth, tillering, and fruit enlargement. Sulfur promotes amino acid synthesis and enhances crop stress resistance, thereby effectively improving the quality of agricultural produce and boosting yields.

Compared to standard nitrogen fertilizers, AOLANSU Agricultural Ammonium Sulfate features stable nutrient content and low volatility, significantly reducing nutrient loss and ensuring adequate nutrient availability throughout the entire crop growth cycle.

2. Wide Compatibility with Soils and Crops

Agricultural Ammonium Sulfate is suitable for almost all field crops, vegetables, fruit trees, and cash crops, including: rice, wheat, corn, soybeans, cotton, tomatoes, peppers, apples, pears, grapes, tea, and more.

It is particularly well-suited for alkaline soils: the product is slightly acidic in nature, allowing it to regulate soil pH levels, improve soil structure, and mobilize nutrients that have become fixed (unavailable) in the soil—thereby resolving the issue of nutrient inactivation commonly found in alkaline environments.

3. Efficient, Green, and Safe Application

- High Utilization Rate: Rapid dissolution and absorption minimize nutrient waste, thereby boosting fertilization efficiency.

- Low Nutrient Loss: Possesses stable chemical properties; resistant to volatilization and leaching loss.

- Pure Formulation: Free from heavy metals and harmful impurities, meeting international standards for agricultural fertilizers.

Production and Quality Control

As a professional manufacturer, AOLANSU implements comprehensive oversight throughout the entire process—from raw material selection to the shipment of finished products:

1. Raw Material Testing: Strict screening of raw materials to detect levels of heavy metals, chloride ions, and harmful impurities.

2. Advanced Processing: Utilizes evaporation-crystallization technology to ensure high product purity and uniform granulation.

3. Batch Quality Inspection: Every production batch is tested according to export standards to guarantee consistent nutrient content and water solubility.

4. Professional Packaging: Available in standard 25kg plastic-lined woven bags, 50kg galvanized iron drums, and 1000kg bulk bags; custom packaging and labeling options are also available.

Application Methods

1. Base Fertilizer: Broadcast and tilled into the soil prior to sowing; recommended dosage is 30–50 kg per mu.

2. Top Dressing: Applied during the crop's growth cycle (e.g., during wheat tillering or rice heading stages); recommended dosage is 20–30 kg per mu.

3. Seed Fertilizer: Can be applied in conjunction with seeds (provided direct contact is avoided) to supply essential nutrients during the seedling stage.

4. Drip/Spray Irrigation: Dissolved in water and applied via fertigation systems for precise nutrient delivery.

Real-World Application Case Study

Case: Wheat Yield Enhancement in Southeast Asia

A large-scale farm in Thailand faced alkaline soil conditions with a pH range of 7.8–8.2. They applied AOLANSU Agricultural Ammonium Sulfate as a top dressing during the wheat tillering stage.

- Application Rate: 25 kg per hectare

- Application Results:

1. Compared to the sole use of standard urea, overall wheat yield increased by 18%;

2. Thousand-grain weight increased by 22%, and grain plumpness improved significantly;

3. Soil pH was slightly adjusted (decreasing by 0.3–0.4), demonstrating a distinct effect on the activation of soil nutrients.- Farmer Feedback: This AOLANSU fertilizer dissolves rapidly, is easy to apply, and offers consistent nutrient efficacy, resulting in a marked improvement in both wheat quality and yield.

FAQ

Q1: Can Agricultural Ammonium Sulfate be used for acid soil?

A1: Yes, it can. Although the product is slightly acidic, it will not significantly reduce the soil pH when used in proper dosage. For acid soil, it is recommended to use it with organic fertilizer together, which can not only supplement nutrients, but also improve soil acidity and avoid soil acidification.

Q2: What is the difference between Agricultural Ammonium Sulfate and ordinary ammonium nitrogen fertilizer?

A2: The biggest difference is that our product contains both nitrogen and sulfur nutrients, which can supplement two essential elements for crops at one time. Compared with ordinary ammonium nitrogen fertilizer, it has higher nutrient utilization rate, is not easy to volatilize, and is more suitable for alkaline soil and crops needing sulfur.

Q3: What is the application dosage of this product for field crops?

A3: The dosage varies according to crop types and soil fertility. For grain crops such as rice and wheat, the dosage is 20-30kg per mu as basal fertilizer, and 10-15kg per mu as topdressing; for cash crops such as cotton and vegetables, the dosage can be appropriately increased to 30-40kg per mu as basal fertilizer.
