Urea (46-0-0) is the global standard for solid nitrogen fertilization. With the highest nitrogen content of any dry fertilizer – 46% – it delivers more plant food per kilogram than any other product. This high analysis translates directly into lower storage, handling, and transport costs, making urea the most economical choice for growers who demand efficient, reliable nitrogen delivery. Whether you grow cereals, oilseeds, rice, or forage, our premium urea granules provide the essential building block for chlorophyll, protein, and yield.

I. Why Urea is the Backbone of Modern Crop Nutrition

Unmatched Nitrogen Concentration
At 46% N, urea contains nearly twice the nitrogen of ammonium sulfate (21%) or ammonium nitrate (34%). Every tonne of urea replaces more than two tonnes of many alternative nitrogen sources. This high nutrient density means fewer bags to handle, less storage space, and lower freight costs – directly improving your bottom line.

Proven, Reliable Performance
Urea has been used for decades across every agricultural region of the world. When properly applied and managed, it delivers rapid vegetative growth, deep green colour, increased tillering, and higher grain protein. For field crops, pasture, and many horticultural systems, urea is the trusted nitrogen source.

Versatile Application Options
Urea can be applied using all standard dry fertilizer equipment: broadcast spreaders, banding units, air seeders, and even dissolved for fertigation (using high‑purity grades). It blends well with most dry fertilizers (MAP, DAP, potash, ammonium sulfate) and is compatible with many crop protection products.

Environmentally Responsible When Managed Correctly
While urea can lose nitrogen through ammonia volatilization, modern best practices – timely incorporation, urease inhibitors, split applications, and placing urea into soil – can reduce losses to near zero. When managed well, urea achieves nitrogen use efficiency equal to or better than other sources.

II. Understanding Nitrogen’s Role in Plants

Nitrogen is the most frequently yield‑limiting nutrient. It is a core component of:

• Chlorophyll – the green pigment that drives photosynthesis.
• Amino acids and proteins – the building blocks of plant tissue.
• Enzymes – catalysts for every metabolic reaction.
• Nucleic acids (DNA, RNA) – the blueprint for growth and reproduction.

Adequate nitrogen produces vigorous early growth, dark green leaves, strong stems, and high yields. Deficiency results in pale, stunted plants, reduced tillering, poor grain fill, and low protein content.

III. Application Guidelines for Maximum Efficiency

Soil Application (Broadcast or Band)

• Rate: 150–400 kg per hectare, depending on crop, yield goal, and soil test.
  • Cereals (wheat, barley, corn): 200–300 kg/ha.
  • Rice (flooded): 150–250 kg/ha (split applications highly recommended).
  • Pasture and forage: 150–300 kg/ha after each cutting.
  • Vegetables: 100–250 kg/ha total, split over 2–4 applications.
• Timing: Apply pre‑plant or as a top‑dress at early tillering/jointing. For corn, apply at planting (starter) and again at V6.
• Critical practice: Incorporate urea into soil within 2–4 days of application to avoid ammonia loss. Light rain or irrigation immediately after application is equally effective.

Top‑Dressing (Standing Crops)

• When: Urea is one of the best materials for top‑dressing cereals, canola, and pasture.
• To reduce volatilization: Apply before light rain (≥5 mm) or irrigate lightly after spreading. On alkaline soils or warm, windy days, urease inhibitors can be added to the urea or applied separately.

Fertigation (Soluble Grade)

• Concentration: 0.5–1.5% solution (5–15 g per litre of water).
• Rate: 20–50 kg per hectare per application.
• Note: Use low‑biuret urea (<0.5%) for fertigation to avoid leaf burn in sensitive crops.

Foliar Spray (Emergency Correction)

• Concentration: 1–2% solution (1–2 kg per 100 L water). Do not exceed 2% to avoid leaf burn.
• Timing: Apply early morning or late afternoon. Repeat every 7–14 days if deficiency persists.
• Additive: A non‑ionic surfactant improves wetting.

Starter Fertilizer (Row Crops)

• Placement: 5 cm beside and 5 cm below the seed.
• Rate: 50–100 kg per hectare of urea (often blended with MAP or DAP). Avoid direct seed contact to prevent germination damage.

V. Best Management Practices to Maximize Urea Efficiency

1. Incorporate or Irrigate
Surface‑applied urea left on warm, dry, alkaline soil can lose 20–30% of its nitrogen as ammonia gas within a few days. Incorporation by tillage or irrigation within 2–4 days reduces losses to <5%.

2. Split Applications
For most crops, applying urea in 2–3 splits (e.g., pre‑plant + top‑dress at tillering + top‑dress at booting) matches nitrogen supply to crop demand, reduces leaching risk, and increases nitrogen use efficiency.

3. Use Urease Inhibitors
Products containing NBPT can be coated onto urea or applied separately. They delay the conversion of urea to ammonia for up to 14 days, allowing time for rainfall or incorporation.

4. Avoid Extreme Conditions
Do not apply urea to very hot (>30°C), windy, or dry soil without immediate incorporation. On frozen or snow‑covered ground, urea is prone to runoff; wait for thawed, workable soils.

5. Soil Test and Tissue Analysis
Base nitrogen rates on realistic yield goals, previous crop, soil organic matter, and nitrate tests. Tissue analysis during the season can fine‑tune top‑dress applications.

VII. Economic and Environmental Benefits

Lowest Cost Per Unit of Nitrogen
Urea is consistently the most affordable solid nitrogen source on a €/kg N or $/lb N basis. This is due to its high analysis and efficient production process.

Reduced Carbon Footprint
Because less product is moved per unit of nitrogen, fuel consumption for transport and application is lower. When managed with inhibitors or split applications, urea’s greenhouse gas (N₂O) emissions are comparable to other nitrogen sources.

Supports High Yields on Limited Land
Efficient nitrogen use with urea allows growers to produce more food per hectare, reducing pressure on natural ecosystems.

VIII. Safety and Handling

Worker Safety
Urea is not classified as hazardous. However, dust may irritate eyes and respiratory tract. Wear gloves, dust mask, and goggles when handling large volumes. If ingested, drink water and seek medical advice.

Storage
Store in a cool, dry, well‑ventilated area, away from acids and moisture. Keep bags off concrete floors (use pallets) to prevent moisture wicking. Shelf life: 24 months. Avoid temperatures above 40°C to prevent caking.

Spill Management
Sweep up dry spills. Do not flush into waterways. Dispose of according to local regulations.
