Granular Urea, also known as coated granular urea or agricultural granular urea, is a premium nitrogen fertilizer designed for superior agricultural performance. With a nitrogen content of 46%, it is the most concentrated solid nitrogen fertilizer available, making it an essential input for crop nutrition and soil enrichment.
Key Characteristics
Nitrogen Content: 46% – ensures maximum crop growth and yield improvement
Particle Size: 2 – 4 mm, suitable for conventional spreading equipment
Form: Larger, uneven particles with robust physical strength
Durability: Less prone to breakage compared to prilled urea, maintaining integrity during handling and application
Precise Spreading: Effective up to 24 meters, ideal for both hand and mechanical spreaders
Main Advantages
High Nitrogen Concentration: Promotes vigorous plant growth and healthy development
Versatility: Can be applied directly to the soil or blended with phosphate and potash to produce complete NPK fertilizer formulations
Robust Physical Properties: Superior handling and reduced dust formation ensure consistent field performance
Efficiency: Provides uniform distribution, reducing fertilizer loss and improving nutrient use efficiency
Applications
Early-Season Grass Fertilization: Supports strong root establishment and rapid growth
Cereal Top-Dressing: Boosts yield potential later in the growing season
Blending: Easily combined with other fertilizers for tailored nutrient solutions
General Agriculture & Horticulture: Widely used across diverse crops and farming practices
Production & Supply
Manufacturers: Khorasan Petrochemical Company and Shiraz Petrochemical Company
Available in bulk shipments, jumbo bags, or custom packaging depending on customer requirements
High Nitrogen Content
Granular Urea contains 46% nitrogen, the highest nitrogen concentration among solid fertilizers. This makes it a potent nutrient source, promoting vigorous plant growth and significantly enhancing crop yield.
Superior Flow & Spreading Characteristics
With its larger particle size (2–4 mm), granular urea provides better flow and spreading properties than prilled urea. It ensures uniform application, reduces the risk of clumping, and improves coverage across large agricultural fields.
Slow Nitrogen Release
Granular urea offers a controlled, slow release of nitrogen, delivering a steady nutrient supply to plants. This minimizes nitrogen loss through volatilization and leaching, leading to higher fertilizer efficiency and reduced environmental impact.
Application Versatility
Can be applied directly to the soil
Easily blended with phosphate and potash to produce balanced NPK fertilizer formulations
Suitable for a wide range of crops and soil conditions
Coverage & Application Rates
Typical application: 15–30 g per square meter
Coverage efficiency: 1 kg treats 33–66 m²
Compatible with both hand spreading and mechanical spreaders for precise, efficient distribution
Physical Durability
Granular urea (coated) features stronger, larger particles than prilled urea, making it less prone to breakage. This robustness ensures consistent application performance and improves nutrient longevity in the soil.
Granular Urea is more than just a fertilizer—it serves as a critical raw material across agriculture, chemical industries, and environmental technologies. Its versatility and high nitrogen content make it valuable in a wide range of applications.
Raw Material for Fertilizer Production
Essential in producing blended and specialized fertilizers
Enhances nutrient delivery for diverse crops and soil conditions
Commonly incorporated into NPK (Nitrogen, Phosphate, Potash) formulations
Melamine Manufacturing
Reacts with formaldehyde to produce melamine
Used in melamine-methanal resins for coatings, laminates, and kitchenware
Benefits from urea’s chemical stability and reactivity
Urea-Formaldehyde Resin Production
Key input in synthesizing urea-formaldehyde resins
Widely applied in adhesives, particleboard, plywood, and wood composites
Provides strength, durability, and cost efficiency for industrial wood products
Reducing Air Pollution
Applied in Selective Catalytic Reduction (SCR) systems in diesel engines
Converts harmful nitrogen oxides (NOx) into harmless nitrogen and water
Helps meet environmental regulations and reduces vehicle emissions
Agricultural Fertilizer
Applied to grasslands early in the growing season to encourage strong growth
Used as top-dressing for cereals later in the season for yield improvement
Ensures robust plant development and higher crop productivity
To meet diverse domestic and international shipment requirements, Urea is packaged and delivered using two primary methods:
Break Bulk
Urea is shipped in loose form without containerization
Loaded directly into ship holds or bulk transport vehicles
Ideal for large-scale bulk shipments where maximum efficiency is required
Jumbo Bags
Urea is packed into secure bags ranging from 50 kg to 1000 kg
Bags are containerized, offering better protection from moisture and environmental factors
Provides ease of handling and flexibility in transportation
Preferred for smaller deliveries or destinations requiring controlled handling
Delivery Terms
International delivery of Urea follows standard Incoterms, clearly defining responsibilities between buyer and seller:
FCA (Free Carrier): Seller delivers goods to a specified location (warehouse/terminal); buyer arranges onward transport.
Ex-warehouse (Buyer’s Pickup): Buyer collects Urea directly from seller’s warehouse and assumes full responsibility for shipment.
FOB (Free on Board): Seller loads Urea onto buyer’s nominated vessel; risk transfers to the buyer once on board.
CFR (Cost and Freight): Seller covers freight costs to the destination port, but the risk passes to the buyer once goods are loaded.
Advantages of Flexible Packaging & Terms
Scalable Logistics: Adaptable for both bulk exports and containerized shipments
Efficiency: Jumbo bags simplify handling, while break bulk maximizes load capacity
Risk Management: Clear Incoterms minimize disputes and ensure smooth delivery operations
