As the world’s most produced and widely used organic nitrogen fertilizer, urea has a nitrogen content of up to 46.67% — the highest among solid nitrogen fertilizers. With high purity, no residue, and no peculiar smell, it is suitable for all crops and soils. Produced using advanced CO₂ synthesis technology, urea features uniform particles, moderate hygroscopicity, and convenient storage and transportation properties. After application, it is converted into ammonium nitrogen by urease, allowing efficient crop absorption and rapid nitrogen supplementation to promote vigorous growth. In addition to agriculture, urea is also widely utilized in industrial, pharmaceutical, and environmental protection sectors, making it a highly cost-effective multi-purpose product for both agricultural and industrial applications.

With a nitrogen content as high as 46.67%, urea provides the highest nitrogen concentration among solid nitrogen fertilizers, delivering rapid nitrogen supplementation and high nutrient utilization efficiency.
As a neutral fertilizer, long-term application does not alter soil pH or cause soil compaction, making it suitable for acidic, neutral, and alkaline soils.
Can be used as base fertilizer, topdressing, and foliar fertilizer. It also serves as a raw material for compound fertilizer production and has applications in industrial, pharmaceutical, and environmental protection fields.
White crystal or powder with uniform particles and moderate hygroscopicity. It is convenient for storage, transportation, and application.
Low toxicity and harmless characteristics make it recognized as a generally safe substance by the FDA. It leaves no harmful residue after application and supports green agricultural practices.
Accounting for approximately 70–80% of total usage, urea is suitable for all crops such as wheat, corn, rice, fruits, vegetables, fruit trees, and cotton. It can be applied as base fertilizer to establish a strong growth foundation, as topdressing for rapid nitrogen supplementation, or through foliar spraying to alleviate yellow leaves and slow growth caused by nitrogen deficiency.
Widely used in the production of urea-formaldehyde resin, melamine, and hydrazine hydrate. It is also applied as a reducing agent in diesel vehicle exhaust treatment systems and as a corrosion inhibitor in metal processing.
Used as a feed additive for ruminants, where it can replace 20–30% of dietary crude protein requirements.
Utilized as a dehydrating agent and humectant in skincare products and pharmaceutical preparations.
White crystal or powder with no peculiar smell, uniform color, no visible impurities, and consistent particle size (1–3mm), providing excellent fluidity.
Fine crystal texture with a smooth hand feel, resistant to agglomeration, and highly soluble in water. After dissolution, the solution remains clear and transparent without precipitation.
Produced through the direct synthesis of ammonia and carbon dioxide, featuring high purity, biuret content ≤0.5%, and no harmful impurities, fully complying with national high-quality urea standards.
Uses thickened woven plastic packaging with built-in moisture-proof inner film and strong sealing performance, effectively preventing moisture absorption and agglomeration. The packaging features clear printing and complete product identification information for convenient storage and handling.
