Urea fertilizer is essential for plant growth and also helps improve soil quality. So, what are the main components of urea fertilizer and what are its uses?


Urea fertilizer provides nitrogen, which promotes growth, development, and increases crop yield. While it offers many benefits for farming, it also has some limitations. Therefore, to better understand urea fertilizer, let's explore this product in detail!


What is urea fertilizer?

Urea fertilizer is a fairly common fertilizer frequently used by farmers to provide the necessary nitrogen for good plant growth. This fertilizer has the chemical formula CO(NH2)2, in the form of white, round, crystalline granules, and contains 45 to 47% nitrogen. Currently, urea is considered the best nitrogen fertilizer due to its high nitrogen content, offering many benefits for plant development.

Composition


Many customers have wondered what the main component of urea fertilizer is. The answer is that the main component of urea fertilizer is nitrogen, as nitrogen makes up about 50% of the urea fertilizer's composition.


Urea fertilizer has the chemical formula CO(NH2)2 and is usually produced in the form of white crystals. It is easy to use, has strong hygroscopic properties, dissolves quickly in water, and converts into nitrate or ammonium forms for easy plant absorption.


Properties of Urea Fertilizer


  • Chemical formula: CO(NH2)2

  • Purity: ≥ 99.5%

  • Moisture content: ≤ 0.5%

  • Solubility in water: 1080g/liter of water at 20°C

  • Melting point: 133°C

  • Biurea: ≤ 0.99%

  • Nitrogen: 46% MIN

  • Biuret: 1.0% MAX

  • Moisture: 0.5% MAX

Currently, there are two types of urea fertilizer on the market: granular urea and pelletized urea (like fish eggs). Although the composition of both types of urea fertilizer is the same, the pelletized form is generally preferred by farmers because it contains an additional moisture-resistant component, allowing for a longer shelf life.

In Agriculture


In agriculture, especially for vegetables, urea fertilizer helps the leaves grow larger and greener. In addition, urea provides the necessary nitrogen to accelerate plant growth and development.


However, you should only apply an appropriate amount to avoid excess nitrate content. When this substance accumulates in agricultural products, it can be harmful to consumer health.


In Livestock Farming


Urea fertilizer is also used in livestock feed for cattle and buffalo. The stomachs of cattle and buffalo contain symbiotic microorganisms that break down cellulose and nitrogen. The urea nitrogen component promotes the growth of these microorganisms, providing the animals with a nutritious source of protein.


However, for animals with fully developed digestive systems, it is important to note that urea fertilizer should not be used as it can easily lead to poisoning. Therefore, urea should not be mixed into animal drinks.

Urea fertilizer is easily soluble and highly adaptable, making it commonly used as a top dressing for crops. To enhance its effectiveness, it's recommended to bury urea fertilizer in the soil to prevent nitrogen loss due to ammonia conversion on the surface.


Alternatively, farmers can dilute urea fertilizer with water to create a watering solution, allowing for better absorption by plants. Furthermore, applying fertilizer during cool weather facilitates decomposition of the urea nitrogen, maximizing its effectiveness.


Urea fertilizer should be used from the early stages of plant growth until fruiting. Its high nutrient content provides all the necessary nutrients for the plants. Farmers can mix urea with other fertilizers to balance nutrient levels, as excess or deficiency can negatively impact growth and yield.


A few things to keep in mind when using urea fertilizer

Urea fertilizer can be used to fertilize acidic soil, but note that it should not be mixed with lime. Mixing them will cause a chemical reaction that hardens the soil and renders the fertilizer ineffective. Ideally, to treat acidic soil, apply lime first and then use urea fertilizer after some time.


Additionally, when using urea fertilizer, blurea formation (where two urea molecules bind together) can occur. When this occurs excessively, it can lead to plant poisoning. To overcome this, farmers should mix urea fertilizer with the soil for 2-3 days before application. At this point, the blurea will hydrolyze and become ammonium carbonate, a nutrient beneficial to plants.


Also, remember not to leave urea fertilizer in direct sunlight. It's best to store it in a sealed bag to minimize air exposure. Exposure to temperature and environmental conditions can easily cause the fertilizer to decompose and lose its quality. Once the fertilizer bag is opened, it should be used as quickly as possible.


Now you understand the main components of urea fertilizer and its role in life, right? Fertilizer use needs to be done correctly with the precise amount depending on each stage and plant variety.
