How to use Urea Properly?|What is urea & How to use urea Fertilizer?

Urea is a widely used nitrogen fertilizer that is essential for promoting plant growth. Knowing how to use urea properly can enhance your gardening or farming results. This guide will cover what urea is, its benefits, and the best practices for using it effectively.

What is Urea?

Urea, also known as carbamide, is a white crystalline substance that contains a high percentage of nitrogen (46%). It is the most concentrated nitrogen fertilizer available and is synthesized from ammonia and carbon dioxide. Urea is highly soluble in water, making it easy for plants to absorb.

Benefits of Urea

  • High Nitrogen Content: Provides a readily available source of nitrogen, which is crucial for plant growth.
  • Cost-Effective: Urea is one of the most economical sources of nitrogen.
  • Versatile: Can be used on a wide range of crops and soils.

How to Use Urea Fertilizer Properly

1. Determine the Right Amount

Why It Matters: Using the correct amount of urea prevents nitrogen burn and ensures optimal plant growth.

Tip: Follow soil test recommendations or general guidelines for your specific crop. Typically, apply 10-15 grams of urea per square meter for vegetables and 20-25 grams per square meter for lawns.

2. Apply Urea at the Right Time

Why It Matters: Proper timing maximizes nitrogen uptake and minimizes losses due to volatilization.

Tip: Apply urea just before planting or during the early growth stages. For crops like wheat, apply it at tillering and booting stages. Avoid applying urea during hot, dry periods to reduce nitrogen loss.

3. Incorporate Urea into the Soil

Why It Matters: Mixing urea into the soil reduces nitrogen loss due to volatilization.

Tip: Use a rake or hoe to incorporate urea into the top 2-3 inches of soil. For larger fields, use mechanical equipment to ensure even distribution and incorporation.

4. Water Immediately After Application

Why It Matters: Watering helps dissolve urea and move it into the root zone, making it available to plants.

Tip: Water the area thoroughly after applying urea to aid in its absorption and reduce the risk of nitrogen loss.

5. Avoid Direct Contact with Seeds or Roots

Why It Matters: Direct contact can cause fertilizer burn, damaging seeds or young plants.

Tip: Apply urea to the soil surface or mix it into the soil, keeping it away from direct contact with seeds or plant roots.

6. Use Urea with Other Fertilizers

Why It Matters: Combining urea with other fertilizers can provide a balanced nutrient supply for your plants.

Tip: Urea can be mixed with phosphorus and potassium fertilizers for a balanced nutrient application. Avoid mixing urea with superphosphate, as it can form insoluble compounds.

7. Store Urea Properly

Why It Matters: Proper storage prevents moisture absorption and maintains the effectiveness of urea.

Tip: Store urea in a cool, dry place, away from moisture and direct sunlight. Keep it in a tightly sealed container to prevent clumping.


Urea is a highly effective and economical nitrogen fertilizer when used correctly. By understanding its properties and following these best practices for application, you can ensure that your plants receive the necessary nutrients for healthy growth. Proper use of urea not only enhances plant productivity but also promotes sustainable gardening and farming practices.
