Prilled Urea (46-0-0): Specification & Supply
Product: Prilled Urea (46-0-0)
Also known as: Prilled Urea 46-0-0, Urea Prills
Chemical formula: CO(NH₂)₂
Standard grade: 46-0-0
Prilled Urea Overview
Prilled urea is a high-nitrogen fertilizer containing 46% nitrogen, the highest concentration among common solid nitrogen fertilizers. It is produced by spraying molten urea into a cooling tower (prilling process), forming small, nearly spherical particles (prills).
Chemically identical to granular urea, prilled urea differs mainly in particle size and physical characteristics. Its smaller size results in faster dissolution and quicker nitrogen availability, making it suitable for applications where rapid nutrient release is desired.

Typical Physical Properties
- Smaller and more spherical than granular urea
- Faster dissolution in soil moisture
- Highly water-soluble
- Free-flowing when properly treated against caking
- Suitable for direct application and certain blending uses
Key Benefits
- Highest nitrogen content
- (46% N) — highly concentrated and cost-effective per unit of nitrogen.
- Faster nutrient release
- — Smaller particle size allows quicker dissolution and more rapid nitrogen availability compared with granular urea.
- Versatile and economical
- — Suitable for a wide range of crops and application methods.
- Easy handling
- — Free-flowing prills support efficient spreading and packaging.
- Proven performance
- — One of the most widely used nitrogen sources in global agriculture.
Recommended Applications
- Highly suitable for:
- Cereals (wheat, rice, maize), sugarcane, cotton, and most field crops
- Situations requiring relatively rapid nitrogen availability
- Direct soil application (broadcast or banded)
- Pasture top-dressing
- Certain industrial uses (resins, adhesives, etc.)
Packing and Shipping
- 50 kg moisture-resistant bags
- 500–1,000 kg jumbo bags (FIBC)
- Bulk (loose) delivery for large-scale use
Storage and Handling
- Store in a cool, dry, well-ventilated warehouse protected from moisture.
- Keep bags sealed and stacked on pallets to prevent caking.
- Avoid contact with ammonium nitrate and strong oxidizers.
- Use standard personal protective equipment; urea dust may cause mild irritation.

FAQ
What nitrogen content is stated?
46.0 min (typically 46.0–46.3) in the technical specifications, with standard grade 46-0-0.
How does the page distinguish prilled from granular urea?
Prilled urea has smaller, more spherical particles and faster dissolution; granular urea has larger, harder particles used for bulk blending and mechanical spreading.
What packing is listed?
50 kg moisture-resistant bags; 500–1,000 kg jumbo bags (FIBC); and bulk (loose) delivery for large-scale use.
