How is urea fertilizer made? This is one of the most common questions asked by fertilizer manufacturers, agricultural professionals, and students interested in modern fertilizer production. Urea is the world’s most widely used nitrogen fertilizer and plays an important role in improving crop growth, productivity, and nitrogen availability in agricultural systems.
The production of urea fertilizer involves the reaction of ammonia and carbon dioxide under controlled industrial conditions. Through a series of chemical and processing steps, these raw materials are converted into high-purity urea that can be used in granular, prilled, and specialty fertilizer products. Today, urea production facilities operate on a large scale to meet the growing global demand for nitrogen fertilizers.
Understanding how urea fertilizer is made helps explain the raw materials, manufacturing technology, and production processes behind one of the most important fertilizers used in modern agriculture.
Detailed industrial fertilizer formulations and fertilizer production technologies are explained in the Chemical Fertilizers Formulations Encyclopedia.

What is Urea Fertilizer
Urea fertilizer is a nitrogen-based fertilizer that contains approximately 46% nitrogen, making it one of the most concentrated solid nitrogen fertilizers available.
Urea is highly soluble in water and can be applied in different agricultural systems including soil fertilization and fertigation. Due to its high nutrient content and economic production process, urea is widely used in both small-scale farming and large agricultural operations.
Raw Materials Used in Urea Production
The industrial production of urea fertilizer requires two primary raw materials:
-
ammonia (NH₃)
-
carbon dioxide (CO₂)
Ammonia is typically produced through the Haber-Bosch process, while carbon dioxide is often obtained as a by-product of ammonia production plants.

Urea Fertilizer Production Process
The industrial manufacturing of urea fertilizer involves several chemical and mechanical stages.
Ammonium Carbamate Formation
The production process begins with the reaction of ammonia and carbon dioxide under high pressure conditions. This reaction forms an intermediate compound known as ammonium carbamate.
Urea Synthesis
Ammonium carbamate is then converted into urea and water through a dehydration reaction inside the reactor system.
Concentration
The resulting urea solution is concentrated through evaporation systems to increase the urea content.
Granulation or Prilling
The concentrated urea is converted into solid fertilizer particles through either prilling or granulation processes. These solid forms improve handling, storage, and fertilizer application efficiency.
Advantages of Urea Fertilizer
Urea fertilizers provide several advantages in modern agriculture:
-
high nitrogen concentration
-
cost-effective fertilizer production
-
efficient nutrient availability
-
suitable for a wide range of crops
These characteristics make urea one of the most widely produced fertilizers in the global fertilizer industry.
Industrial Fertilizer Formulations Guide
Detailed fertilizer formulations and industrial fertilizer production technologies are explained in the Chemical Fertilizers Formulations Encyclopedia. This professional guide provides practical information about fertilizer formulation development and fertilizer manufacturing technologies.
Modern urea plants are usually integrated with ammonia plants in order to improve energy efficiency and reduce production costs.
SUMMARY
Urea fertilizer is one of the most important nitrogen fertilizers used in modern agriculture. It is produced through the reaction of ammonia and carbon dioxide under high pressure conditions. The production process includes ammonium carbamate formation, urea synthesis, concentration, and granulation or prilling stages.
