Agricultural Nitrogen Fertilizer

AOLANSU Agricultural Nitrogen Fertilizer consists of uniform white to off-white granules characterized by excellent flowability, high water solubility, and resistance to caking, making it easy to store, transport, and apply. The product is refined using high-purity nitrogen raw materials combined with eco-friendly auxiliary agents; it is free from biuret, heavy metals, and excessive chloride ions. Consequently, it is safe and harmless for long-term use, posing no risk of contamination to soil or crops.

Key Product Highlights

1. Strict Standard Compliance

Strictly adheres to the Chinese National Standard GB/T 15063-2020 and international agricultural market access standards, with comprehensive quality control implemented throughout the entire process—from raw material selection to finished product dispatch.

2. High Nutrient Utilization Rate

Features an optimized formula that significantly minimizes nitrogen volatilization and loss, achieving a nutrient utilization rate exceeding 50%—far surpassing the typical 15%–30% utilization rate of traditional nitrogen fertilizers.

3. Extensive Applicability

Compatible with the vast majority of crops and suitable for all soil types—acidic, alkaline, or neutral—meeting the diverse requirements of both open-field and greenhouse cultivation environments.

4. Safe, Green, and Eco-friendly

Contains no biuret, thereby avoiding the inhibition of seed germination or damage to root systems; minimizes nutrient runoff, effectively balancing the goals of increased crop yield with ecological preservation.

Advanced Production Process

AOLANSU Agricultural Nitrogen Fertilizer is professionally manufactured using the industry-leading tower-based melt granulation technology. This process yields granules of uniform size with smooth surfaces and high structural hardness, ensuring they remain intact and resist caking during storage and long-distance transportation. The production line operates stably at full capacity year-round, guaranteeing ample production volume and a secure, reliable supply of goods.

Rigorous Quality Control Throughout the Entire Process

1. Raw Material Selection: Raw materials undergo strict testing for purity and the presence of harmful substances to ensure full compliance with both national and international standards.

2. Process Monitoring: Key stages—such as granulation, drying, and cooling—are monitored in real-time to guarantee stable and consistent product performance.

3. Finished Product Testing: Every batch is analyzed by a professional laboratory to verify critical parameters, including total nitrogen content, moisture levels, particle size, and solubility, ensuring stable and reliable quality.

Scope of Application and Application Methods

1. Suitable Crops and Soils

- Field Crops: Rice, wheat, corn, soybeans, etc.

- Vegetable Crops: Tomatoes, peppers, cucumbers, and various leafy greens.

- Fruit and Forestry Crops: Fruit trees such as apples, pears, grapes, citrus, etc.

- Suitable Soils: Compatible with acidic, alkaline, and neutral soils; suitable for both open-field cultivation and greenhouse farming.

2. Flexible Application Methods

- Base Fertilizer: Broadcast or furrow-applied prior to sowing to establish a nutritional foundation for crop growth.

- Top Dressing: Applied via spot application or drip irrigation during critical growth stages (e.g., rice tillering stage, corn "large trumpet" stage).

- Mixed Application: Can be blended with mainstream agricultural inputs—such as phosphorus fertilizers, potassium fertilizers, and organic fertilizers—to provide complementary nutrients and enhance overall fertilization efficacy.

Real-World Application Case Study

Case: Corn Cultivation Application in North China (2024)

At a large-scale corn cultivation base in Hebei Province (covering 500 mu), AOLANSU Agricultural Nitrogen Fertilizer was applied as a top dressing during the corn "large trumpet" stage at a rate of 30 kg per mu. A control group in an adjacent plot received traditional urea at a rate of 40 kg per mu.

- Yield Increase: The plot treated with AOLANSU nitrogen fertilizer achieved a yield of 680 kg per mu—a 12% increase compared to the control plot treated with traditional urea, which yielded 607 kg per mu.

- Cost Savings: Fertilizer usage was reduced by 25%, nitrogen loss was lowered by 40%, and the comprehensive cultivation cost per mu was reduced by approximately $28 USD. - Growth Performance: Maize plants exhibit robust growth, deep green foliage, and enhanced photosynthetic activity, with no adverse effects such as root burn or lodging.

- Grower Feedback: AOLANSU agricultural nitrogen fertilizer significantly improves nitrogen uptake efficiency, resulting in reduced fertilizer usage and higher yields; furthermore, long-term application does not deplete soil fertility.

FAQ

Q1: What is the main function of this Agricultural Nitrogen Fertilizer? Which crops are suitable for?

A1: The main function of this product is to supplement nitrogen nutrients needed by crops, promote the growth of crop stems and leaves, enhance photosynthesis, make plants robust, and improve crop yield and quality. It is suitable for almost all crops, including field crops such as rice, wheat and corn, vegetables such as tomatoes and peppers, and fruit trees such as apples and grapes, especially for crops that are sensitive to nitrogen and have high demand for nitrogen.

Q2: How to use this product? What is the recommended dosage? 

A2: It can be used as basal fertilizer or topdressing. The application method can be broadcasting, furrow application, hole application or drip irrigation. The recommended dosage varies according to crop types and soil fertility: 15-20kg per mu for grain crops such as rice and wheat (as topdressing); 20-30kg per mu for vegetables and fruit trees (as topdressing); 25-35kg per mu when used as basal fertilizer. It can be adjusted appropriately according to actual planting conditions.

Q3: Can this product be mixed with other fertilizers? Are there any precautions for use? 

A3: Yes, it can be mixed with phosphorus fertilizer, potassium fertilizer and organic fertilizer to achieve complementary nutrients and improve fertilization effect. It should be noted that it cannot be mixed with alkaline fertilizers, so as to avoid chemical reactions that reduce nutrient effectiveness; when used as basal fertilizer, it should be kept 8-15cm away from seeds or crop roots to prevent root burn; it should be stored in a cool and dry place to avoid moisture and caking.
