Urea is widely used fertiliser with a high nitrogen content, transported around the world in bulk or in bags depending upon the infrastructure of the importing area.
Urea can be obtained semi-naturally from the body fluids and urine of animals, termed Animal Urea, but as a commercial commodity is more often chemically derived, such as from methane/formaldehyde, and termed Technical Urea.
A major export of Alaska, the Middle East, Romania, Russia, and Germany, in particular, although potentially an export of any nation blessed with supplies of natural gas. Urea in bulk requires especially clean and dry cargo compartments.
A considerable quantity of Artificial Fertilizers are moved in bulk in small ships over short sea distances, the specialized trades in these areas preferring ships with steel rather than with wooden ceilings.
Urea shippers insist always on steel ceilings but exporters of certain other products may accept ships with timber flooring in case of need, although they will be acutely conscious of the cleanliness of the timber and will prefer the less moisture absorbing hardwood rather than ships fitted with softwood ceilings.
Softwood tends to attract essential moisture from Artificial Fertilizer, which moisture helps create a consistent and uniform granular shape to the product, causing the delivery of undesirable Powdered Fertiliser.
These products can also be damaged by suction/vacuvator discharge, receivers preferring the cargo to be handled by grabs which again means that ships with steel ceilings/tank tops will have an advantage.

Bulk Urea Stowage Factor
The stowage factor of bulk urea is a measure of the space required to stow a given amount of urea in a ship. It is typically expressed in cubic meters per metric ton (m³/MT) or cubic feet per long ton (ft³/LT). The stowage factor can vary depending on the form of urea, such as prilled or granular, as well as other factors affecting space utilization.
In general, the stowage factor for bulk urea ranges from approximately 0.9 to 1.1 m³/MT (or 32 to 39 ft³/LT). However, these values are indicative and may not be applicable in all situations. The actual stowage factor for a specific cargo of urea will depend on its unique characteristics and the specific conditions of the shipment.
To determine the most accurate stowage factor for bulk urea, it is advisable to consult with a surveyor, shipping agent, or other experts who have experience in handling and transporting urea cargo. This information will help ensure efficient space utilization and optimal loading and stowage of the cargo, ultimately contributing to the safe and cost-effective transportation of the urea.
Types of Urea
Urea is a widely-used nitrogen-based fertilizer that comes in various forms to suit different agricultural applications. The primary types of urea include:
- Prilled urea: Prilled urea is a small, spherical, and solid form of urea produced by spraying liquid urea into a prilling tower, where it cools and solidifies into small, uniform beads. Prilled urea has a slightly lower nitrogen content compared to granular urea (typically around 46% nitrogen). It is generally used as a direct-application fertilizer or as a component in blended fertilizers.
- Granular urea: Granular urea is produced by a different manufacturing process than prilled urea, resulting in a larger, more irregularly-shaped particle. The granules are created by spraying liquid urea onto a bed of solid urea particles and then allowing it to solidify. Granular urea typically has a slightly higher nitrogen content than prilled urea (usually around 46-48% nitrogen) and is less susceptible to caking, making it more suitable for bulk storage and handling.
- Urea ammonium nitrate (UAN): UAN is a liquid fertilizer that combines urea, ammonium nitrate, and water. It typically contains around 28-32% nitrogen, with varying ratios of urea and ammonium nitrate. UAN can be applied directly to the soil, through fertigation systems, or as a foliar spray. Its liquid form makes it convenient for blending with other nutrients and applying in various ways.
- Coated or controlled-release urea: Coated urea is a type of urea that has been treated with a polymer or sulfur coating to slow down the release of nitrogen into the soil. This controlled-release mechanism can help reduce nitrogen loss due to leaching or volatilization, improving the efficiency of nitrogen uptake by plants. Coated urea is typically more expensive than standard urea products, but it can offer benefits in specific agricultural settings, such as sandy soils or areas with high rainfall.
- Urea formaldehyde (UF): Urea formaldehyde is a slow-release nitrogen fertilizer created by polymerizing urea with formaldehyde. This process forms a water-insoluble compound that slowly releases nitrogen as it decomposes in the soil. UF fertilizers can help reduce nitrogen loss and improve nutrient use efficiency in specific agricultural settings. However, they are generally more expensive than standard urea products and may not be suitable for all crops or soil types.
These different types of urea offer various advantages and disadvantages, depending on factors such as the specific nutrient requirements of the crop, soil conditions, and application methods. Selecting the appropriate type of urea for a particular agricultural context is essential for ensuring optimal plant growth and yield.
