Agricultural Urea Fertilizer, also known as Carbamide Fertilizer, is a high-concentration nitrogen fertilizer with the chemical formula CO(NH₂)₂. Containing approximately 46.4% nitrogen, urea provides one of the highest nitrogen concentrations among commonly used solid fertilizers.
Nitrogen is a key nutrient for plant growth, especially for chlorophyll formation, leaf development, protein synthesis, and overall crop biomass production. Agricultural Urea is widely used when crops require additional nitrogen during active growth stages.
Due to its high nitrogen content, excellent water solubility, and compatibility with different application methods, urea fertilizer is commonly used for cereals, vegetables, industrial crops, and fruit plantations.
AOLANSU Agricultural Urea contains ≥46.4% nitrogen, providing an efficient nitrogen source for crops during periods of rapid growth. It helps improve leaf development, plant vigor, and crop nutrient balance when additional nitrogen is required.
The concentrated nitrogen content also helps reduce fertilizer volume compared with lower-nitrogen fertilizers, improving transportation and application efficiency.
Agricultural Urea has excellent water solubility, allowing farmers to apply it through multiple methods according to different cultivation conditions.
This flexibility makes urea fertilizer suitable for both traditional farming and modern precision agriculture.
The biuret content of AOLANSU Agricultural Urea is controlled at ≤1.0%, helping reduce potential risks associated with excessive biuret exposure during crop application.
The product is suitable for a wide range of crops, including corn, wheat, rice, cotton, vegetables, and fruit trees.
AOLANSU produces granular urea with a controlled particle size of 2-4mm. The uniform granules provide better flowability during transportation, storage, and mechanical spreading.
With moisture content ≤0.5%, the fertilizer maintains stable physical performance when stored in dry and ventilated conditions.
The production of Agricultural Urea begins with the controlled reaction between ammonia and carbon dioxide. AOLANSU monitors production conditions to maintain stable conversion efficiency and consistent nitrogen concentration.
After synthesis, molten urea is processed into uniform granules. Particle size control improves spreading accuracy and reduces handling problems during transportation and fertilizer application.
Finished urea granules undergo drying and screening processes before quality inspection. Each batch is checked for nitrogen content, biuret content, moisture level, and physical appearance before shipment.
AOLANSU Agricultural Urea was applied in a corn cultivation project located in Qihe, Shandong, China. The farmland covered approximately 300 mu (around 20 hectares), where urea was used as nitrogen supplementation during different crop growth stages.
The application focused on improving nitrogen availability during the period of rapid corn growth. Field observations showed stronger leaf color, improved plant growth consistency, and better crop development compared with areas without additional nitrogen management.
The farmer feedback indicated that AOLANSU granular urea provided convenient spreading performance due to its uniform particle size and maintained stable fertilizer effectiveness throughout the growing season.
AOLANSU Agricultural Urea is available in standard and customized packaging options according to customer requirements.
AOLANSU supports international fertilizer supply with export documentation, quality certificates, and logistics coordination. The company serves agricultural markets in Southeast Asia, Africa, South America, and Europe.
AOLANSU supports trial orders for customers who want to evaluate fertilizer performance before establishing long-term cooperation. Product samples and technical information can be provided according to customer requirements.
For fertilizer distributors, agricultural suppliers, and large farming projects, AOLANSU provides stable-volume Agricultural Urea supply with factory-direct cooperation models.

Agricultural Urea typically contains approximately 46.4% nitrogen, making it one of the most concentrated solid nitrogen fertilizers available for crop production.
The high nitrogen concentration allows farmers to supply sufficient nitrogen nutrition with relatively small fertilizer quantities.
The application timing depends on crop type, soil condition, and growth stage. Urea is commonly used as top dressing during periods when crops have high nitrogen demand, such as the vegetative growth stage.
It can also be applied as basal fertilizer before planting or combined with irrigation systems through fertigation.
Yes. Agricultural Urea can be used for foliar application after proper dilution. Low-concentration urea solutions are commonly applied to crop leaves when rapid nitrogen supplementation is required.
The recommended concentration depends on crop variety and application conditions.
Agricultural Urea is suitable for a wide range of crops, including corn, wheat, rice, cotton, vegetables, fruit trees, and other nitrogen-demanding plants.
It is widely used in both small-scale farming and large agricultural production systems.
Urea should be stored in a dry and ventilated warehouse, protected from moisture and direct exposure to humid environments.
Keeping packaging sealed and avoiding contact with water helps maintain granule quality and reduces caking during storage.
Urea can be combined with many fertilizer products depending on crop requirements. However, compatibility should be considered before mixing with other materials to avoid nutrient loss or reduced fertilizer performance.
AOLANSU provides factory-direct Agricultural Urea supply with professional production management, strict quality inspection, and international export experience.
AOLANSU focuses on fertilizer production and provides Agricultural Urea solutions designed for different agricultural applications and market requirements.
From raw material inspection to final packaging, AOLANSU monitors important quality indicators to ensure stable fertilizer performance.
