Why Choose Nitrogen Fertilizer Urea 46% for Your Crops?
Urea N46% is the most concentrated and cost-effective solid nitrogen fertilizer available on the global market. With 46% elemental nitrogen — the highest nitrogen content of any commercially produced solid fertilizer — it provides outstanding value per ton of nitrogen delivered to the field. It is used in over 50% of all global nitrogen fertilizer applications across every major crop and climate zone.
Highest nitrogen content — 46% N
Urea delivers 46% nitrogen per metric ton — more than twice the nitrogen of ammonium sulfate (21%) and significantly more than ammonium nitrate (34%). Less product is needed per hectare, directly reducing freight, storage, handling, and application costs per unit of nitrogen delivered. Nitrogen Fertilizer Urea 46% Wholesale Supplier
Fast-acting — rapid nitrogen release
Urea undergoes rapid hydrolysis in soil, converting to ammonium ions (NH₄⁺) within 24–72 hours of application. Plants absorb ammonium directly from soil solution, delivering a fast and visible growth response — particularly important for topdressing cereal crops, vegetables, and pastures during active growth periods.

Versatile — multiple application methods
Urea N46% can be broadcast, band-applied, side-dressed, dissolved for fertigation, or applied as a dilute foliar spray. This versatility makes it the nitrogen source of choice across all farming systems — from large-scale grain production to intensive horticulture and plantation crops. Nitrogen Fertilizer Urea 46% Wholesale Supplier
Safe to transport and store
Unlike ammonium nitrate, urea poses no fire or explosion hazard. It is classified as non-hazardous under international shipping regulations, dramatically simplifying port handling, cargo insurance, and customs procedures for bulk importers across all markets.
Compatible with NPK blending programs
Granular urea blends easily with MOP (potassium chloride), superphosphate (SSP/TSP), and other granular fertilizers to produce custom NPK bulk blends. It is the nitrogen backbone of virtually every commercial bulk blending program worldwide. Nitrogen Fertilizer Urea 46% Wholesale Supplier
Highly soluble — ideal for liquid application
Urea dissolves completely in water with no residue, making it suitable for fertigation through drip and sprinkler systems. Prilled urea dissolves even faster than granular, making it the preferred form for liquid blending and foliar application programs.
Environmentally responsible nitrogen source
Urea production generates fewer pollutants than many alternative nitrogen fertilizers. When properly incorporated or irrigated in, nitrogen losses are minimised — supporting responsible, sustainable farming and helping growers meet environmental compliance targets.

What makes Urea N46% the world's most used fertilizer?
Urea (CO(NH₂)₂) was first produced in 1828 and today is manufactured industrially from anhydrous ammonia (NH₃) and carbon dioxide (CO₂). The resulting compound contains 46% elemental nitrogen — the highest nitrogen concentration of any commercially produced solid fertilizer. Over 50% of all global nitrogen fertilizer consumption is accounted for by urea. Nitrogen Fertilizer Urea 46% Wholesale Supplier
When applied to soil, urea undergoes hydrolysis catalyzed by the enzyme urease, converting to ammonium carbonate and then to ammonium ions (NH₄⁺), which plant roots absorb directly. In warm, alkaline, or dry conditions, some nitrogen may be lost as ammonia gas — making timely soil incorporation or irrigation essential after surface application.
Urea is sold in two main forms:
- Granular urea: Harder, irregular-shaped particles (2–4mm). Preferred for bulk blending, mechanical spreading, and broadcast application. Slower to dissolve than prills.
- Prilled urea: Smooth, round beads (1–4mm). Preferred for fertigation, liquid blending, foliar spray, and dissolution applications. Slightly faster to dissolve than granular.
Key quality parameters for importers
Always verify: N% ≥46%, biuret ≤1.0%, moisture ≤0.5%, granule/prill size 1–4mm, free ammonia ≤160 PPM. Request SGS or Intertek pre-shipment inspection — Gro Export Ltda facilitates this at the loading port for every contracted order.
⚠️ Volatilization — prevent nitrogen loss
Do not leave urea on moist soil surfaces in warm conditions without incorporation or rainfall within 24–48 hours. Ammonia volatilization losses can reach 30–50% in hot, alkaline, or humid conditions. Always incorporate urea into the soil or irrigate immediately after surface application to maximise nitrogen use efficiency.
Buy bulk urea fertilizer from a trusted wholesale fertilizer supplier
Urea N46% is the universal nitrogen source for commercial agriculture worldwide — effective across all major crop types, soil conditions, and growing regions.
Rice & Paddy
Broadcast into standing water 7–10 days after transplanting. Essential for tillering and grain filling.
Maize / Corn
Side-dress at V4–V6 growth stage. Top-dress at V8 for maximum yield benefit during rapid growth.
Wheat & Barley
Apply at planting and as topdressing in early spring. Drives tillering, stem extension, and grain protein.
Sugarcane
Apply at planting and ratoon cycles. High nitrogen demand throughout the growing season — split applications recommended.
Vegetables
Fertigate via drip or dissolve for foliar spray. Low-biuret urea is safe for foliar feeding at 0.5–1% solution.
Citrus & Fruits
Fertigate or foliar-feed through the growing season. Apply at flowering and fruit development stages.
Coffee & Tea
Topdress around the canopy drip-line. Apply before the rainy season for best uptake in plantation systems.
Oil Palm
Apply in split applications around the palm frond circle. High nitrogen demand makes urea the most cost-effective source.
Pasture & Grass
Broadcast before rain events. Highly responsive to nitrogen — urea consistently delivers the lowest cost per unit of dry matter production.
Flowers & Ornamentals
Use low-biuret prilled urea for foliar spray on sensitive ornamental crops. Drives rapid vegetative growth and intense colour.

Best practices for applying Urea N46% across different farming systems, crop types, soil conditions, and irrigation methods to maximise nitrogen use efficiency.
Broadcast and incorporate
Broadcast urea evenly across the field surface and incorporate immediately by tillage — or irrigate with at least 6mm within 24 hours. Prevents ammonia volatilization from moist, warm soil surfaces. Most common method for cereal, grain, and pasture crops.
Band application
Apply urea in bands 5 cm below and to the side of seed rows (2×2 placement). Concentrates nitrogen near emerging roots for rapid uptake and reduces surface volatilization losses. Improves nitrogen use efficiency, especially in coarse soils.
Fertigation — drip / sprinkler
Dissolve urea in the fertilizer tank and inject through the irrigation system. Complete water solubility ensures no clogging. Apply at low concentrations (0.5–2%) frequently for maximum efficiency. Ideal for vegetables, fruits, and plantation crops.
Foliar spray
Dissolve urea at 0.5–2% concentration for foliar application. Use low-biuret urea (≤0.9% biuret) to avoid leaf damage on sensitive crops. Spray during cool periods (early morning or evening). Provides rapid nitrogen response when root uptake is limited.
Topdressing cereals
Apply urea to the soil surface of established cereal crops during early growth stages. Ensure rainfall or irrigation within 24–48 hours to dissolve and move nitrogen into the root zone. Split into 2–3 applications for best efficiency in high-rainfall areas.
NPK blending
Granular urea is the nitrogen base for all major NPK bulk blends. Ensure similar granule sizes when blending to minimise segregation. Do not blend urea directly with superphosphate — blend immediately before application only to avoid moisture absorption and product degradation.
💡 Tips for maximum nitrogen use efficiency
Split applications always outperform single large applications. Two or three smaller urea applications through the growing season improve nitrogen uptake efficiency by 20–35% compared to one large pre-season application. In high-rainfall or irrigated systems, apply urea close to peak crop nitrogen demand periods — typically during rapid vegetative growth and canopy development.
⚠️ Do not mix dry urea with superphosphate
Dry mixing of urea with single or triple superphosphate produces a sticky, hygroscopic mixture that is difficult to spread and may cause equipment blockages. These products should always be blended immediately before application and spread immediately — never stored as a pre-mixed blend. For fertigation, never mix concentrated urea solution with calcium fertilizers — calcium urea phosphate precipitation may occur.
