Nitrogen is one of the primary nutrients required for crop development. It contributes to chlorophyll formation, protein synthesis, enzyme activity, and vegetative growth. With ≥46.0% total nitrogen, this fertilizer provides a concentrated nutrient source that can be incorporated into crop nutrition programs when nitrogen demand increases.
The 2.0–4.0 mm particle range, with at least 90% of the product within the specified size, helps improve spreading consistency. Uniform granules flow smoothly through fertilizer equipment and reduce the risk of excessive powder or uneven distribution across the field.
The product is completely soluble in water at 20°C, providing flexibility for different agricultural application methods. Depending on the crop and local farming system, it can be incorporated into conventional fertilizer programs or used in suitable water-based nutrient applications.
With moisture content controlled at ≤0.5%, the product is designed to maintain good physical condition during storage and transportation. Proper moisture-proof packaging and warehouse management can further reduce caking and help preserve granule quality during long-distance shipment.
For international distributors and commercial farms, supply consistency is as important as fertilizer performance. AOLANSU supports bulk orders, regular procurement programs, customized packaging, and export documentation to help customers maintain stable inventory throughout the agricultural season.
Nitrogen demand changes throughout the crop growth cycle. Young plants require nitrogen to establish leaves and stems, while rapidly developing crops need sufficient nitrogen to maintain vegetative growth and support later yield formation. An appropriate nitrogen management program therefore considers crop species, soil fertility, growth stage, weather conditions, and the availability of other nutrients.
AOLANSU Agricultural Nitrogen Fertilizer can be incorporated into a broader nutrient management strategy rather than used as the sole fertilizer source. Combining nitrogen with appropriate phosphorus, potassium, organic matter, and secondary nutrients can help growers maintain a more balanced fertility program.
AOLANSU uses professional granulation equipment to convert nitrogen raw materials into consistent agricultural-grade granules. Process parameters are controlled to achieve the required particle size, physical strength, and flow characteristics.
After granulation, controlled drying and screening help reduce excess moisture and separate particles outside the target size range. This process supports more consistent product appearance and mechanical spreading performance.
Finished batches are inspected for nitrogen content, moisture, particle size distribution, biuret content, solubility, and appearance. Products are released for shipment only after meeting the agreed quality requirements.
AOLANSU can provide moisture-resistant packaging and customized labeling solutions for international distributors. Packaging specifications can be discussed according to order volume, destination-market requirements, and customer branding needs.
Nitrogen is particularly important during the active vegetative stages of cereals. The product can be used as a basal fertilizer or top dressing for corn, wheat, rice, and other field crops. Proper timing helps provide nitrogen when crop demand increases and supports uniform plant development.
Vegetables such as tomatoes, peppers, cucumbers, leafy greens, and other commercial crops require adequate nitrogen during vegetative development. The fertilizer can be incorporated into crop-specific fertilization programs through broadcasting, furrow application, or other locally appropriate methods.
Fruit trees such as apples, grapes, citrus, and pears require carefully managed nitrogen throughout different growth stages. AOLANSU Agricultural Nitrogen Fertilizer can provide nitrogen supplementation during periods of active foliage and branch development while allowing growers to coordinate nitrogen application with phosphorus, potassium, and other nutrients.
For farms managing hundreds or thousands of hectares, application efficiency and predictable fertilizer handling are important operational considerations. Uniform granules and stable storage characteristics make the product suitable for large-scale mechanical spreading and centralized fertilizer procurement.
The fertilizer can be incorporated into the soil before sowing or transplanting to establish an initial nitrogen supply. When used as basal fertilizer, the application should follow local agronomic recommendations and avoid direct concentrated contact with seeds or sensitive roots.
Top dressing is suitable when crops enter periods of rapid vegetative growth or increased nitrogen demand. Application timing and quantity should be adjusted according to crop species, soil nutrient levels, weather, and local fertilization practices.
For better overall nutrient balance, the product can be incorporated into fertilizer programs together with suitable phosphorus and potassium fertilizers or organic amendments. Soil testing and crop nutrient requirements should be considered when establishing a complete fertilization plan.
A large-scale corn farm in Hebei Province introduced AOLANSU Agricultural Nitrogen Fertilizer as a top-dressing component during the active crop growth period. The farm previously experienced inconsistent plant development across different field sections and wanted to improve nitrogen management while maintaining practical application efficiency.
The fertilizer was mechanically distributed across the treated area according to the farm's crop management program. Following application, field observations showed greener foliage, stronger vegetative development, and more uniform plant growth compared with the previous fertilization program.
The farm also reported improved fertilizer management efficiency and reduced unnecessary fertilizer input while maintaining stable crop performance. The case highlights how appropriate nitrogen timing, uniform granular fertilizer distribution, and crop-specific nutrient planning can work together in commercial corn production.
Nitrogen requirements vary according to soil fertility, organic matter, crop rotation, rainfall, irrigation, and previous fertilizer applications. Buyers should develop application rates based on local soil analysis and professional agronomic recommendations rather than applying a fixed rate to every field.
When applying concentrated nitrogen fertilizer as a basal fertilizer, sufficient separation from seeds and young roots should be maintained according to local agricultural practices. This helps reduce the risk of excessive localized nutrient concentration.
Keep fertilizer in a dry, cool, and well-ventilated warehouse. Moisture-proof packaging should remain intact during storage, and opened bags should be resealed promptly to reduce moisture absorption and caking.
