Urea یوریا

What it is

Urea carries 46% nitrogen — the highest N concentration of any common solid fertilizer. Plants take up its nitrogen as ammonium and then nitrate after soil microbes convert it. Because the nitrogen is highly soluble, it is normally split into two or three applications rather than applied all at once.

Benefits

• Highest nitrogen per kilogram, so less product to transport and handle
• Suitable for basal and top-dressing applications
• Works across cereals, cotton, sugarcane, maize and vegetables

Precautions

• Nitrogen can volatilize as ammonia if urea sits on the ground surface — on hot, windy days losses start within hours, so irrigate or incorporate within a day of application
• Avoid mixing with superphosphate in the same application heap for long storage
• Do not exceed the recommended dose: excess nitrogen causes lodging and delays maturity

Application guidance

Apply as per the calculated dose, split into basal + 1–2 top-dressings at active growth stages (e.g. wheat: sowing, crown-root initiation ~21 days, flowering). Broadcast evenly and irrigate lightly afterwards where possible.
