Your Essential Guide to Urea (46% Nitrogen) Fertiliser

Welcome to your guide on Urea (46% Nitrogen) – one of the most widely used and effective nitrogen fertilisers in the world. With its exceptionally high nitrogen content, Urea is a powerful tool for promoting lush vegetative growth, greener leaves, and higher crop yields. Whether you’re growing lawns, vegetables, fruit trees, or large-scale crops, Urea provides the fuel plants need for strong, vigorous growth.

In this guide, we’ll explore the role of nitrogen in plant health, when to use Urea, and how to apply it effectively while avoiding common pitfalls.

Why Choose Urea?

Urea is prized for its high nitrogen concentration (46%), making it the most economical solid nitrogen fertiliser available. Once applied to the soil, Urea quickly breaks down into plant-available nitrogen forms, providing both immediate and sustained benefits.

Key Benefits:

? Maximum Nitrogen Power
Delivers the highest nitrogen boost of any solid fertiliser – perfect for driving rapid growth in nitrogen-hungry plants.

? Lush Green Growth
Encourages strong root and shoot development, improves leaf colour, and speeds up lawn recovery.

? Versatile Applications
Ideal for lawns, vegetables, fruit trees, pastures, and broadacre crops – widely trusted by both home gardeners and commercial farmers.

? Water-Soluble & Flexible Use
Can be applied directly to soil, dissolved for fertigation, or used in foliar sprays.

⚠️ Use With Care on Sensitive Crops
Some plants, especially citrus trees, may be sensitive to Urea or to excessive nitrogen application. Always apply at the recommended rate and avoid over-fertilisation, which can burn roots or cause imbalanced growth.

When to Use Urea

Urea is particularly beneficial in these situations:

Lawns & Turf: For rapid greening, fast lawn recovery, and dense growth.
Vegetables & Leafy Greens: Provides essential nitrogen for spinach, lettuce, cabbage, and other leafy crops.
Fruit Trees: Useful in early growth stages, but apply cautiously to citrus and avoid overuse during flowering or fruiting.
Field Crops & Pastures: A cost-effective nitrogen source for cereals, corn, and grazing pastures.
Correcting Nitrogen Deficiencies: Ideal when plants show pale, yellowing leaves or weak growth.

How to Apply Urea

⚠️ Note: Application rates depend on soil conditions, crop type, and growth stage. Overuse can harm plants and contribute to nutrient loss.

? For Small Gardens & Potted Plants

Preparation: Dissolve 20 g of Urea in 10 liters of water.
Application: Apply to soil at the base of plants every 2 weeks during active growth.
Tip: Avoid direct contact with leaves unless diluted as a foliar spray.

? For Vegetable Gardens & Flower Beds

Soil Application: Spread 30 g per m² evenly, then water in well.
Liquid Feed: Dissolve 20 g in 10 liters of water and apply at the base.
Frequency: Every 3 weeks during active growth.

? For Lawns

Broadcast Application: 10 g per m² (around a small handful per square meter).
Tip: Apply before rain or water in immediately to prevent nitrogen loss.

? For Fruit Trees (including Citrus)

General Application: 150 g per mature tree, spread evenly around the root zone, avoiding direct contact with the trunk.
Caution for Citrus: Use smaller amounts (50–100 g per tree), apply only during active growth (spring/summer), and avoid overuse to prevent leaf burn or excessive vegetative growth at the expense of fruiting.

? For Large-Scale Farms & Pastures

Field Crops (Wheat, Corn, etc.): 40–80 kg per hectare as top dressing.
Pasture Improvement: 40–60 kg per hectare to boost grazing quality.
Foliar Spray: 0.5–1% solution (5–10 g per liter of water).

Why Gardeners Trust Urea

✔ Highest nitrogen content available (46%).
✔ Boosts rapid, green vegetative growth.
✔ Fully water-soluble and easy to apply.
✔ Cost-effective for both home and large-scale farming.
✔ Widely trusted by gardeners, farmers, and turf managers.

FAQs About Urea

1. Can Urea burn plants?
Yes, if over-applied or left on dry soil. Always water in well and follow recommended rates.

2. Is Urea safe for citrus trees?
Yes, but apply sparingly and avoid overuse. Citrus trees can be sensitive to too much nitrogen, which may cause excessive leaf growth and reduced fruiting.

3. Can I mix Urea with other fertilisers?
Yes, but avoid mixing with alkaline materials (like lime or ash) as this may cause nitrogen loss.

4. How quickly does Urea work?
Plants typically respond within days when conditions are moist and warm.
