Application and Functions of Urea Fertilizer

Learn how urea fertilizer enhances plant growth and soil health with its high nitrogen content, suitable for agriculture and home gardens alike.

Are you aware that urea represents one of the most concentrated forms of accessible nitrogen?

Urea fertilizer is a commonly utilized nitrogen source for plant nourishment. It gives plants significant nutrients for proper expansion and maintenance. It is a white, crystalline substance that is extremely soluble in water. 

Using urea as a fertilizer can enhance soil quality and crop yield. It is essential to contemporary agriculture. Continue reading to learn about the application and functions of urea fertilizer in detail.

Understanding Urea Fertilizer

The three main nutrients that fertilizers supply are potassium, phosphorus, and nitrogen. In the agricultural sector, urea, a component of nitrogen fertilizer, is often used to foster the development of plants and improve crop yields. Plants may easily absorb it due to its high water solubility and straightforward chemical composition (CO(NH2)2). 

Let’s find out some of the benefits of urea fertilizer:

  • The high nitrogen concentration of urea fertilizer is one of its main benefits. It improves the entire fertility of the soil in addition to treating the plant’s nitrogen shortage. 
  • The best part is that urea may be used in nearly every type of soil due to its neutral pH.
  • It is also a cost-effective option as it is less expensive than other fertilizers.

The Greek terms hydro (water) and lysis (break) are the roots of the term hydrolysis. By introducing water, the hydrolysis process breaks down big molecules into smaller ones.

Moreover, plants take up nitrogen from urea either directly or by hydrolysis, a process in which soil bacteria convert urea into ammonium or nitrate. Plants can grow and yield nutritious crops when they are ready to take in nitrogen from urea.

Applications of Urea Fertilizer

Here are the applications of urea fertilizer: 

  • In agricultural settings, urea fertilizer is regularly applied to crops to supply vital nutrients like nitrogen. As a result, it enhances crop life and performance and results in larger harvests.
  • Urea can also be applied in the flowering phase. Small blooms are a sign of a lack of nitrogen in plants. Plants can be given urea fertilizer to cope with such conditions.
  • Fertilizer containing urea is also widely used in residential gardens and gardening. To provide plants the nutrients they need for proper development, you can opt to add urea fertilizer to your flower beds or veggie garden.

For example – If you grow tomatoes in your backyard, you may fertilize with urea to make sure the plants receive sufficient nitrogen to grow big, juicy fruits. Homeowners can encourage their plants to grow well and yield abundant harvests by applying urea fertilizer to their gardens.

  • Urea fertilizer can be employed in commercial settings, like sports grounds and golf courses, alongside agricultural fields and personal gardens. Applying urea fertilizer can help landscapers keep the lawn looking green and bright while encouraging strong grass growth. For instance, urea fertilizer could be used by a golf course superintendent to make sure that the fairways and greens are in optimal performing condition. 
  • Chelated iron is formed when urea reacts with Fe2+ in the form of complexes. It is an inexpensive organic iron fertilizer. It works well to stop chlorosis caused by iron shortage. It is preferable to avoid applying 0.3% urea to 0.3% ferrous sulfate in the leaves rather than applying ferrous sulfate in a single spray. 

You might use urea fertilizer in these settings to improve the appearance and create a well-maintained atmosphere for fun and relaxation.

Urea Fertilizer and Soil Health

Urea fertilizer is crucial for preserving the health of the soil. It can be done in the following ways:

  • Supplying necessary nutrients to the soil, 
  • Regulating micronutrients, 
  • Strengthening the structure of the soil, and 
  • Combining with other fertilizers to create diverse mixes.

When urea is applied to soil, ammonia and nitrates will be produced by microorganisms. It results in increased organic matter and nutrient retention. 

Moreover, this procedure emits carbon dioxide, which changes the pH of the soil and encourages plant development. Increased organic matter content improves crop yields and supports biodiversity. It is the basic role of urea fertilizer in maintaining soil health.

When applying urea, it’s critical to adhere to the proper application rates. As you know, overuse can have negative effects on the environment and plants.


Urea is an organic form of nitrogen fertilizer. It passes through crops via soil urease. As a result, urea should be sprayed every 4 to 8 days during this crucial time.

The significance of urea fertilizer in sustainable agriculture is discussed in this article. You also learned about its benefits for plant development, nutrient uptake optimization, and environmental protection.

1. Can I use urea in my home garden?

Yes, in your home garden, urea can be applied as a nitrogen fertilizer. It gives plants the necessary nutrients they need for rapid development and the growth of fruits and vegetables.

2. How long does urea fertilizer take to dissolve in the soil?

It usually takes a few minutes to hours for urea fertilizer to dissolve in the soil. Moreover, it may vary based on the temperature and volume of water in the soil.

3. How can I store urea fertilizer safely?

Urea fertilizer should be kept in a closed, cool, and secure space to protect it from weather and theft hazards.

4. What are the environmental concerns with urea use?

Issues involving the release of greenhouse gasses, contamination of waters, algal blooms, and toxic air pollutants can arise from the manufacture and usage of urea.
