Urea 46

Introduction to Urea 46

Urea (CO(NH₂)₂) is the most widely used nitrogen fertilizer worldwide, offering the highest nitrogen concentration among solid fertilizers — typically 46% Nitrogen by weight.
It plays a critical role in modern agriculture by supporting rapid vegetative growth, improving yields, and enhancing crop quality across a wide range of plant species.

Urea is a white, crystalline organic compound, easily soluble in water, produced synthetically by combining ammonia (NH₃) and carbon dioxide (CO₂) under high pressure and temperature.

Importance and Applications of Urea 46

Thanks to its high nitrogen content, Urea 46 is vital for:

Field Crops: wheat, corn, barley, rice
Vegetable Crops: tomatoes, potatoes, cucumbers
Fruit Trees: citrus, apples, grapes
Pasture and Forage Crops
Industrial Applications: adhesive manufacturing, resins, plastics, and even in some DEF (Diesel Exhaust Fluid) systems for NOx reduction

Application Methods:

Broadcast over fields
Incorporated into soil
Fertigation (water-soluble versions)
Foliar sprays (diluted solutions)

Types of Urea 46

Urea 46 is mainly available in two commercial forms:

Type	Description	Typical Use
Prilled Urea	Small, smooth spherical particles (1–2 mm)	General field applications
Granular Urea	Larger, harder granules (2–4 mm) with better flowability	Mechanized spreading (fertilizer spreaders)

Differences Between Prilled and Granular Urea

Property	Prilled Urea	Granular Urea
Size	Smaller (1–2 mm)	Larger (2–4 mm)
Hardness	Softer, more fragile	Harder, more resistant to crushing
Spreading	Shorter spread radius	Longer spread radius (better for large fields)
Dissolution	Dissolves faster in water	Dissolves slightly slower
Application	Suitable for manual or small-area applications	Ideal for mechanical spreaders

Technical and Chemical Characteristics

Property	Typical Value
Nitrogen Content (Total N)	46.0% min
Biuret Content	≤ 1.0% – 1.5%
Moisture Content	≤ 0.5%
Free Ammonia (NH₃)	≤ 160 ppm
pH (10% solution)	7.0–7.5
Solubility in Water	1080 g/L at 20°C
Melting Point	132–135°C
Bulk Density	720–770 kg/m³ (Prilled), 740–800 kg/m³ (Granular)

Physical Properties

Appearance: White crystals, prills, or granules
Odor: Odorless
Hygroscopicity: Moderate (absorbs moisture from air)
Dust: Minimal in granular, moderate in prilled types
Flowability: High in granular types due to particle hardness

Storage and Handling

Store in cool, dry, and well-ventilated areas.
Avoid direct exposure to humidity and water.
Use moisture-resistant packaging materials (e.g., laminated PP bags).
Use anti-caking agents for long-term storage.

Standards and Compliance

Our Urea 46 products are produced and tested according to:

ISO 9001:2015 Quality Management Standards
ISO 22241-1 (for automotive DEF-grade Urea)
FAO Fertilizer Standards
REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals)
Local Ministry of Agriculture Fertilizer Regulations

Environmental Responsibility

Urea applications must be managed properly to minimize nitrogen losses due to volatilization (NH₃ gas release) and leaching (nitrate groundwater pollution).
Use of urease inhibitors and slow-release formulations can greatly reduce environmental impact.
