Granular Urea
Also known as: Urea 46-0-0, Granular Urea N46 Chemical Formula: CO(NH₂)₂ Standard Grade: 46-0-0
Granular Urea is the most widely used solid nitrogen fertilizer in the world. It contains the highest concentration of nitrogen among common dry fertilizers (46% N) and is valued for its high nutrient density, cost-effectiveness, and versatility across a wide range of crops and soil types.
Urea is produced by reacting ammonia with carbon dioxide under high pressure and temperature, followed by granulation to form hard, free-flowing granules that are easy to handle, store, and apply.
Technical Specifications
| Parameter | Unit | Typical / Standard Value |
|---|---|---|
| Total Nitrogen (N) | % | 46.0 min (typically 46.0–46.3) |
| Biuret | % | ≤ 1.0 (often ≤ 0.8–1.0) |
| Moisture | % | ≤ 0.5 |
| Particle Size | mm | 2.0–4.5 (typically ≥ 90% in 2–4 mm range) |
| Appearance | — | White free-flowing granules |
| Bulk Density (approx.) | kg/m³ | 750–850 |
| Crushing Strength | kgf | ≥ 2–3 (depending on grade) |
| Formaldehyde / Conditioning Agent | % | Present in treated grades (anti-caking) |
Typical Physical Properties
- Highly water-soluble
- Free-flowing with good spreading characteristics
- Treated with anti-caking agents for improved storage and handling
- Suitable for bulk blending with most fertilizers (compatibility checks recommended)
Key Benefits
- Highest nitrogen concentration among solid fertilizers — reduces transport, storage, and application costs per unit of nitrogen.
- Cost-effective — One of the most economical sources of nitrogen available.
- Versatile application — Suitable for broadcasting, banding, blending, and (with care) fertigation or foliar use (low-biuret grades preferred for foliar).
- Promotes vigorous growth — Supports rapid vegetative development, higher yields, and improved crop quality.
- Easy handling — Granular form allows accurate mechanical spreading and bulk blending.
- Wide crop adaptability — Effective on virtually all crops and soil types when managed correctly.
Recommended Applications
Highly suitable for:
- Cereals: Wheat, rice, maize/corn, barley
- Oilseeds, sugarcane, cotton, and most field crops
- Vegetables, fruits, and horticultural crops
- Pasture, forage, and grassland management
- Forestry and reforestation programs
Application Methods:
- Broadcast or banded before or during the growing season
- Incorporated into the soil or applied just before rainfall/irrigation to minimize ammonia volatilization
- Bulk blending with phosphorus and potassium fertilizers
- Split applications to match crop nitrogen demand
Best Practices:
- Apply when soil is moist or incorporate lightly to reduce nitrogen losses through volatilization.
- Avoid surface application on high-pH or dry soils without incorporation or rainfall.
- Match rates to soil tests, crop requirements, and growth stage.
Packaging Options
- 50 kg moisture-resistant bags
- 500–1,000 kg jumbo bags (FIBC)
- Bulk (loose) delivery for large-scale agricultural and industrial use
Storage & Handling Recommendations
- 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 can cause mild irritation.
Summary
Granular Urea (46-0-0) remains the cornerstone nitrogen fertilizer for global agriculture due to its high analysis, affordability, and flexibility. When applied with good agronomic practices, it delivers efficient nitrogen nutrition that drives strong crop growth and high yields across a wide range of farming systems.
