Our factory is strategically situated within Shandong’s core agricultural chemical hub, equipped with professional production lines and advanced environmental protection facilities, and holds dual certification under the ISO 9001 Quality Management System and ISO 14001 Environmental Management System.

- Raw Materials: We select high-purity liquid ammonia and carbon dioxide, strictly controlling purity right from the source.

- Manufacturing Process: We employ a mature ammonia stripping process involving synthesis, granulation, drying, and screening stages, resulting in uniform granules with excellent flowability that resist caking.

- Quality Control: A professional quality inspection team supervises the entire production process; a Certificate of Analysis (COA) is provided for every batch, ensuring that all parameters are fully traceable and verifiable.

Key Product Advantages

1. High Efficiency and Rapid Absorption

AOLANSU Agricultural Urea boasts a nitrogen content of ≥46.4%, providing a steady supply of nitrogen to crops throughout their entire growth cycle. Its excellent water solubility allows for versatile application methods—including fertigation, foliar spraying, and broadcasting—offering operational convenience and reducing labor costs. The granules are of an optimal size (2–4 mm), making them resistant to washout by rainwater; this facilitates a slow release of nitrogen, boosting fertilizer utilization efficiency by 30%–50% and minimizing nutrient waste.

2. Safe, Gentle, and Versatile

With a biuret content of ≤1.0%, the product remains well within the safe threshold for crops, effectively preventing seed burn and seedling damage. Furthermore, it contains no harmful impurities, ensuring it does not contaminate soil or groundwater—a perfect alignment with the principles of green and sustainable agriculture. Suitable for grain crops, cash crops, fruit trees, and various soil types; can be applied as a basal fertilizer, top dressing, or foliar spray. It can be used independently or blended with phosphorus and potassium fertilizers to ensure balanced nutrition.

3. Stable, Durable, and Easy to Transport

With a moisture content of ≤0.5%, the product maintains its quality for 24 months under normal storage conditions (in a cool, dry, and ventilated environment). It is packaged in 25kg or 50kg moisture-proof, wear-resistant woven bags; custom packaging and bulk transport options are available. Ideal for long-distance shipping and on-field storage, we maintain ample year-round inventory to guarantee timely delivery during peak seasons.

Real-World Application Case Study

Case: Increased Corn Yield in Shandong (Grain Crop)

At a 300-mu (approx. 20-hectare) cornfield in Qihe, Shandong, AOLANSU Agricultural Urea was applied (40 kg/mu as basal fertilizer + 20 kg/mu as top dressing during the jointing stage). A control plot within the same field was treated with standard urea. The results demonstrated:

- The corn developed more robust root systems and sturdier stalks, resulting in significantly enhanced resistance to lodging (toppling);

- The per-mu yield reached 680 kg—a 7.2% increase compared to the control plot—with improved grain plumpness, generating an additional revenue of approximately 120 RMB per mu;

- Farmer Feedback: "The granules are uniform and do not clump together, making manual spreading effortless. The fertilizer effect is stable and consistent, ensuring the crops do not suffer from nutrient deficiency during the later growth stages."

FAQ

Q1: Can your agricultural urea be used for all kinds of crops?

A1: Yes. Our agricultural urea has strong versatility, suitable for almost all food crops, cash crops and fruit trees, such as rice, wheat, corn, cotton, vegetables, apples and citrus. The biuret content is ≤1.0%, which is safe for all crops, and will not cause seed burning or seedling damage. Our factory in China has tested the fertilizer effect on various crops, ensuring good adaptability.

Q2: What is the best way to use agricultural urea to improve fertilizer efficiency?

A2: It can be used as base fertilizer, topdressing and foliar fertilizer. As base fertilizer, it can be mixed with soil and applied to the plough layer to provide long-term nitrogen nutrition for crops; as topdressing, it can be broadcast or irrigated, which is convenient and fast; as foliar fertilizer, it can be diluted with water to 0.5%-1.0% concentration and sprayed on crop leaves, which is suitable for the peak period of crop nutrient demand. We can provide detailed application guidelines for free.

Q3: Why choose your China supplier for agricultural urea procurement?

A3: We have our own factory in China, which can provide factory-direct prices, reducing your procurement costs. We have rich production experience and strict quality control, ensuring stable product quality and consistent fertilizer effect. We also provide sufficient stock, timely delivery and complete export documents, which can fully meet your bulk procurement needs.

Q4: How to store agricultural urea to avoid caking?

A4: It should be stored in a dry, ventilated and cool warehouse, away from moisture, high temperature and rainy days. The packaging should be kept intact to prevent moisture absorption. Our agricultural urea is processed by low-temperature drying and added with anti-caking agents, which can effectively reduce the caking probability. If caking occurs, it can be crushed gently and used normally without affecting the fertilizer effect.
