Urea is a chemical compound that contains nitrogen and is a nutrient for plants. This fertilizer is available in the form of small granules and can be easily spread on the soil. The use of granular urea increases the growth and development of plants and also improves the efficiency of agricultural products.
Granular urea fertilizer is a widely used nitrogen fertilizer in agriculture, which is very effective for increasing the growth of plants due to having the highest amount of nitrogen (46%) among all solid fertilizers. Nitrogen in granular urea enhances vegetative growth (green parts of the plant) and increases crop production.
The production of urea consists of several steps, starting with the synthesis of ammonia and carbon dioxide. These two components are combined in a reactor under high pressure and temperature to form ammonium carbamate – an intermediate compound. Next, the ammonium carbamate is further broken down into urea and water through a process called “stripping”. This involves removing excess ammonia from the mixture by heating it, which results in its removal.
After being separated from impurities, these crystals are then dried and granulated to obtain the final product – granulated or granulated urea. The size and shape of these pellets can be adjusted according to the specific needs for different industries.

What is Granular Urea?
Granular urea contains 46% nitrogen and is known as a rich source of this element. Its appearance is a white crystal and it consists of ammonia and carbon dioxide. All plants need nitrogen, a substance that helps the formation of plant leaves and protein formation and affects the production of chlorophyll.
Nitrogen is available in the air, but plants are not able to take nitrogen from the atmosphere. Granular urea acts quickly on plants. These fertilizers have a high solubility (1079 g/l at 20 degrees Celsius). Therefore, in addition to the soil, they can also be absorbed through the foliage of the plant, although the method of injection into the soil is always recommended to increase the amount of nitrogen absorption. Granular urea, as its name suggests, is obtained from a special chemical formula in the laboratory.
The difference between granule and prill fertilizer
Prilled and granular urea fertilizers are two types of nitrogenous fertilizers that are widely used to increase production and improve the quality of agricultural products. These two types of fertilizers have differences in their appearance, production process, properties and applications. In the following, we will examine the difference between Prilled and Granule chemical fertilizers together.
The main difference between these two types of fertilizers is their form and shape. Prilled fertilizer is a type of nitrogen fertilizer that is produced in powder form. In fact, urea-peril fertilizer is in the form of small and fine grains and is easily dissolved in water. However granular urea fertilizer is produced in the form of larger grains and is suitable for soils with heavy and sandy textures.
Urea granular fertilizer has advantages such as easy dissolution in water, the ability to accumulate in the soil, and quick absorption by plants. But granular fertilizer has other advantages such as slow release of nitrogen in the soil, reducing the possibility of soil sealing, and reducing environmental pollution.
Chemical Formula | The chemical formula for granular urea is CO(NH₂)₂. This formula represents the compound urea, which contains two amine groups (-NH₂) attached to a carbonyl group (C=O). Simple yet effective for delivering nitrogen to plants. |

Production Process of Granular Urea
The production method of Granular urea is that this chemical substance is obtained by hydrating calcium cyanamide. With the development of ammonia manufacturing technology, the direct method of making urea from ammonia and carbon dioxide has also improved. In a more modern method, these two substances are combined to produce a substance called ammonium carbamate. Then, the ammonium carbamate is converted to urea by releasing a molecule of water.
When urea reacts with carbon dioxide and anhydrous ammonia, urea is produced. This process is carried out under high pressure and at a temperature of 180 degrees Celsius, and the urea obtained from this process is called peril in the form of solid grains.
Key Benefits of Granular Urea
- High Nitrogen Content: Efficiency in plant growth.
- Slow Release: Reduces nitrogen loss through volatilization.
- Better Handling and Storage: Lower dust formation than prilled urea.
- Cost-Effectiveness: Widely available and affordable.
Applications of Granular Urea
Granular urea is a widely used form of nitrogen fertilizer with various applications across different industries. Here are some of the critical uses of granular urea:
- Agricultural Applications
- Field Crops: Ideal for cereal crops like wheat, rice, and corn, where it promotes strong growth and high yields.
- Vegetable Crops: Enhances the growth of vegetables such as tomatoes, cucumbers, and leafy greens.
- Fruit Trees: Supports the development of fruit trees like apples, oranges, and pears by providing essential nitrogen.
- Pastures and Hay Fields: Used to increase the growth rate and nutrient content of grasses for livestock feed.
- Lawn and Garden Uses
-
Lawns: Provides a lush, green appearance and promotes thick, healthy grass.
-
Gardens: Used to nourish a variety of garden plants, flowers, and shrubs.
- Industrial Uses
- Resins and Adhesives: Used in manufacturing urea-formaldehyde resins.
- Animal Feed Additive: Non-protein nitrogen source for ruminants.Explosives and Chemicals: Component in ammonium nitrate-based explosives.
