Briefing
Urea N:46%Min Prilled 0.85-2.8mm offers high-efficiency nitrogen. Choose Urea prilled (0.85-2.8mm) or Urea granular (2-4.75mm) for optimal solubility and application needs.
Detailed
What is Urea?
Urea (CO(NH₂)₂) is the world's most widely used nitrogen fertilizer, containing 46% nitrogen (N) - the highest concentration among solid nitrogen fertilizers. Available in both granular (2-4.75mm) and prilled (0.85-2.8mm) forms, urea provides cost-effective nitrogen delivery for all major crops. Our urea meets ISO 1592 and FERTILIZING PRODUCTS REGULATION (EU) 2019/1009 standards.
Core Features
1.Advantages:
· Dust-free formulation reduces nitrogen loss during handling
· Low hygroscopicity (≤0.5% moisture) prevents caking in humid climates
2. Optimized for Different Applications
· Granular Urea (2-4.75mm):
Ideal for mechanical broadcast spreaders
20% slower dissolution rate for extended nitrogen release
Preferred for rice/wheat base applications
· Prilled Urea (0.85-2.8mm):
Faster dissolution (90% in 15 minutes)
Perfect for fertigation and foliar sprays
Best for vegetable/cash crop top-dressing
Stability & Performance
1. Field Efficiency
Nitrogen Utilization: 50-60% efficiency (vs 30-35% for ammonium nitrate)
Soil Adaptability: Performs well in pH 5-8 soils
Crop Safety: Low biuret content prevents phytotoxicity
2. Storage & Handling
Shelf Life: 24 months in original packaging
Bulk Storage: Compatible with concrete/steel silos (humidity <70%)
Safety: Non-flammable, UN 2071 classification

Application
1） Cereal Crops (Wheat, Corn, Rice)
Base Application: 150-200kg/ha granular urea (2-4.75mm) incorporated pre-planting
Stimulates tiller formation in wheat (30-40% increase)
Reduces nitrogen runoff in paddy rice versus ammonium fertilizers
2）Vegetable & Horticultural Crops
Foliar Spray: 2% urea solution during fruit expansion
Rapid nitrogen uptake boosts leaf growth in leafy greens (harvest 7-10 days earlier)
3）Cash Crops (Sugarcane, Cotton, Tobacco)
Split Application: 200-250kg/ha granular urea (2-4.75mm) at planting + 6 weeks
Maintains tobacco leaf thickness and combustibility
4）Pasture & Forage Productions
Broadcast: 100-150kg/ha granular urea before rainy season
Doubles dry matter yield in ryegrass/alfalfa

Storage Environment Requirements
✦Temperature & Humidity Control: Optimal storage temperature: -10℃~40℃ (extreme heat may accelerate slow hydrolysis; ≤-10℃ may embrittle packaging). Humidity must be <60% (≥70% humidity causes 15% caking within 3 days).
✦Ventilation & Light Protection: Store in cool, well-ventilated warehouses, away from direct sunlight (UV may slightly accelerate oxidation, reducing Fe content by 2%-3% long-term). Keep away from heat sources (e.g., radiators, boilers).

FAQ
Why choose granular over prilled urea?
A: Granular (2-4.75mm) offers better mechanical spreading accuracy and 20% slower release, while prilled (0.85-2.8mm) dissolves faster for quick-response applications.
Is your urea suitable for organic farming?
A: Conventional urea is synthetic, but we offer organic-compliant urea from natural sources (OMRI-listed option available).
How to prevent nitrogen loss during application?
A: Incorporate within 24 hours of surface application or use controlled-release coatings (available upon request).
