Ammonium Sulfate Blended Fertilizer

AOLANSU Ammonium Sulfate Blended Fertilizer is a mechanically blended granular fertilizer. Formulated using high-quality ammonium sulfate as its primary ingredient and produced via a precise blending process, it ensures balanced nutrient content and a steady release rate. This meets the full-cycle nutritional requirements of field crops, vegetables, fruit trees, and various cash crops.

As a professional manufacturer based in China, our factory features modern production workshops and strictly adheres to industrial blending standards. From raw material selection, precise formulation, and uniform mixing to granulation, every stage of the process undergoes rigorous quality control. This ensures that every batch of product features uniform granules and stable nutrient levels, meeting export-grade quality requirements. The product's granule diameter is controlled within the range of 2.0–4.75 mm; its uniform appearance, excellent flowability, and low dust content make it compatible with various fertilization methods—including mechanized broadcasting and drip irrigation—while also facilitating long-distance transport and long-term storage without caking. This guarantees both the efficiency and precision of application.

Core Nutrients and Product Advantages

1. Dual-Action Nutrients: Enhancing Quality and Yield

Unlike single-nutrient fertilizers, AOLANSU Ammonium Sulfate Blended Fertilizer combines ammonium nitrogen with effective sulfur elements, creating a synergistic dual-nutrient effect. Nitrogen promotes leaf growth and stimulates chlorophyll synthesis, while sulfur participates in protein synthesis; together, they significantly enhance both the quality and yield of crops. This makes the fertilizer particularly suitable for leafy vegetables, gramineous crops (grasses/cereals), and various cash crops.

2. Soil Improvement and Broad Adaptability

The fertilizer is slightly acidic in nature, effectively improving nutrient availability in alkaline soils, minimizing nitrogen volatilization losses, and reducing nutrient wastage. With consistent and proper application over time, it improves soil structure, enhances soil microbial activity, and prevents soil compaction. It is adaptable to all soil types, demonstrating particularly outstanding results when applied to alkaline soils.

3. Superior Physical Properties & Convenient Application

- Uniform Granules: Standard granule size of 2.0–4.75 mm ensures uniform spreading and excellent soil penetration, minimizing localized nutrient accumulation.

- Low Dust: Strict dust control during production ensures an eco-friendly and safe application process, while also reducing operational losses.

- Non-Caking: Treated with a special process to ensure high stability under normal storage conditions; remains free-flowing and does not cake even after long-term storage.

- High Compatibility: Compatible for blending with most conventional fertilizers; contains no excessive chloride, making it safe and harmless for chloride-sensitive crops (such as garlic, onions, fruit trees, etc.).

Applicable Crops & Application Methods

1. Applicable Crops

AOLANSU Ammonium Sulfate Blended Fertilizer is widely suitable for various grain crops, cash crops, and fruit & vegetable crops, including—but not limited to—rice, wheat, corn, soybeans, cotton, garlic, onions, various fruit trees, and tea plants.

2. Application Methods

- Base Fertilizer: Uniformly broadcast prior to sowing and then incorporated into the soil via plowing to establish a solid nutrient foundation for crop growth.

- Top Dressing: Applied via side-dressing or spot application during critical growth stages (e.g., tillering stage, fruiting stage) to rapidly replenish nutrients.

- Mechanized Application: Compatible with various fertilizer application machinery, allowing for uniform spreading over large areas and significant savings on labor costs.

- Drip Irrigation Application: Features excellent water solubility; can be dissolved and applied through drip irrigation systems to deliver nutrients precisely to the root zone.

Real-World Application Case Study

Case: Southeast Asian Rice Cultivation Base (2024)A large-scale rice cultivation base in Southeast Asia (covering an area of  5,000 mu) faced challenges in previous years due to alkaline soil conditions, severe nitrogen loss, poor rice tillering, and low yields. In 2024, the base selected AOLANSU Ammonium Sulfate Blended Fertilizer to serve as both the base fertilizer and the top dressing during the tillering stage, applying it at a rate of 25 kg per mu for the base application and 15 kg per mu for the top dressing. Performance Feedback: Rice tillering increased by 18%, leaves became deep green and robust, and the incidence of pests and diseases decreased. At maturity, grain heads were plump and full; actual measured yields per mu (unit of land area) rose by 22% compared to previous years. Fertilizer utilization efficiency improved significantly, soil alkalinity was ameliorated, and farmers' overall cultivation costs were reduced by 12%.    

Product Specifications

Rigorous Quality Control, Export-Grade Quality

Our factory strictly adheres to export-grade quality standards, subjecting every product batch to multiple layers of testing:

1. Raw Material Screening: Impurities are removed, and the nutrient content of raw materials is strictly controlled.

2. In-Process Monitoring: Uniformity is monitored in real-time during the mixing process to ensure consistent nutrient distribution.

3. Finished Product Sampling: Random checks are conducted on granule size, moisture content, nutrient composition, and stability; products are released from the factory only after passing these tests.

4. Comprehensive Certification: We provide COAs (Certificates of Analysis), MSDSs (Material Safety Data Sheets), and a complete set of documents required for customs clearance, ensuring full compliance with global trade regulations.

Stable Supply, Flexible Service

1. Ample Inventory: We maintain year-round stock to meet demand during global peak planting seasons, thereby eliminating supply delays.

2. Flexible Packaging: Standard packaging consists of 25kg or 50kg PP woven bags (lined with PE film), offering moisture resistance and durability; custom packaging and labeling options are available.

3. Flexible Ordering: We accept trial orders starting from just 1 ton, allowing farmers to verify the product's compatibility with their local soil and crops; large-volume purchases qualify for direct-from-factory pricing.
