Urea fertilizer is a cornerstone of modern crop nutrition, known for its high nitrogen content and adaptability across a wide range of crops and climates. But when it comes to selecting the most effective form—granular or liquid urea fertilizer—farmers and agronomists must evaluate multiple factors including application methods, crop needs, and storage logistics. This guide explores the key differences between granular and liquid urea, offering insight into which format is best suited for specific farming systems.
Physical Characteristics of Granular Urea Fertilizer
Granular urea is one of the most commonly used nitrogen fertilizers worldwide, prized for its compact form, high concentration (46% N), and broad compatibility with different soil types.
Key physical attributes include:
Solid prilled or granulated form, easy to handle and transport.
Water-soluble, allowing for uniform breakdown under moist conditions.
Slow to moderate release, depending on soil moisture and temperature.
Granular products like Ugarit 10-0-5 + 70% Organic Matter, which blends urea-based nitrogen with humic and fulvic acids, improve soil structure while feeding plants. Similarly, Ugarit 27-27-27 + TE offers balanced NPK with trace elements, ideal for base applications in field crops.
When to Choose Liquid Urea Fertilizer
Liquid urea is synthesized by dissolving granular urea in water, often enhanced with additives to improve foliar absorption or compatibility with fertigation systems. It is the format of choice when precision, fast action, or tank mixing are needed.
Choose liquid urea fertilizer when:
Applying through drip irrigation or foliar spray systems.
Targeting quick nitrogen uptake in early vegetative stages.
Application Methods for Urea Fertilizer in Both Forms
Different urea formats demand distinct application strategies to maximize efficiency and minimize losses through leaching, volatilization, or runoff.
Granular Urea Application:
Granular products are best applied through:
Broadcast spreaders, especially before rainfall or irrigation.
Banding near the root zone for targeted uptake.
Top-dressing in cereals or pastures for sustained feeding.
? Tip: Combine granular urea with sulfur-rich products like Ugarit Multi(30% K?O, 32% S, 10% CaO) to balance nutrient ratios and improve nitrogen utilization.
Liquid Urea Application:
Liquid formulations are ideal for:
Fertigation through drip or sprinkler systems.
Foliar sprays, especially in early stages or nutrient stress scenarios.
Tank mixing with micronutrients for customized solutions.
? For instance, Ugarit Cereal (15% N, 2% Cu) targets cereal crops with a nitrogen-copper synergy critical for enzyme function and tillering.
Urea Fertilizer Effectiveness by Format
Effectiveness of urea depends on its conversion into plant-available forms (ammonium and nitrate), which is influenced by format, climate, and soil conditions.

? Scientific Note: According to the International Fertilizer Association (IFA), urease inhibitors or coated urea granules significantly reduce ammonia losses. For example, Ugarit 25-25-25 + TE offers balanced release and trace elements, ideal for sustained nutrition.
Storage and Shelf Life of Urea Fertilizer Types
Proper storage preserves nutrient quality and ensures safe handling. The two formats require different conditions to maintain stability:
Granular Urea:
Shelf life of 12–24 months in dry, well-ventilated areas.
Susceptible to caking and moisture absorption, especially in humid regions.
Requires moisture-proof packaging and protection from direct sunlight.
Liquid Urea:
Typically stable for 6–12 months, depending on formulation.
Must be stored in non-corrosive tanks (e.g., polyethylene or stainless steel).
Sensitive to freezing temperatures or microbial contamination if organics are present.
?? For example,Ugarit DKP (33% P?O?, 44% K?O) in liquid form is shelf-stable and ideal for high-value crops during flowering and fruiting stages.
Final Recommendations: Which Urea Fertilizer Should You Choose?
Choosing between granular and liquid urea depends on your application infrastructure, crop cycle, climatic conditions, and desired nutrient efficiency.
Use granular urea when:
You need cost-effective bulk fertilization for field crops.
You have limited fertigation capabilities.
You plan pre-plant or top-dress application before rain.
Use liquid urea when:
You employ fertigation systems or foliar feeding.
You require fast nitrogen delivery in early growth stages.
You’re blending nutrients for targeted high-value crops.
