Urea 46% is a solid nitrogen fertilizer that contains 46% nitrogen in the form of urea. It is a white crystalline substance that is highly soluble in water. Urea is one of the most widely used nitrogen fertilizers globally due to its high nitrogen content and versatility.

Urea is a synthetic organic compound that is produced from ammonia and carbon dioxide. It is the most common nitrogen fertilizer because of its high nutrient concentration and relatively low cost. Urea is used in both agriculture and industry.

In agriculture, urea is primarily used as a source of nitrogen for crops. Nitrogen is an essential nutrient for plant growth and plays a vital role in the formation of proteins, enzymes, and chlorophyll. Urea is applied to the soil or as a foliar spray, and once it dissolves in water, it undergoes hydrolysis to release ammonium ions and hydroxide ions. The ammonium ions are converted to nitrate by soil microorganisms through a process called nitrification, making it available for plant uptake.

Urea 46% fertilizer contains one main component, which is urea. Urea is a nitrogen-containing compound with the chemical formula (NH2)2CO. It is made up of carbon, hydrogen, nitrogen, and oxygen atoms. In the case of urea 46%, it means that the fertilizer contains 46% nitrogen in the form of urea.

Urea is a synthetic organic compound that is produced through the reaction of ammonia and carbon dioxide. It is highly soluble in water, making it readily available for plant uptake. Once applied to the soil or used as a foliar spray, urea undergoes hydrolysis, a chemical reaction in the presence of water, which converts it into ammonium and hydroxide ions. The ammonium ions can be further converted into nitrate through nitrification, a process carried out by soil bacteria.

Why nitrogen in important:
The high nitrogen content in urea 46% makes it a concentrated source of nitrogen for plants. Nitrogen is a crucial nutrient for plant growth and plays a vital role in various physiological processes. It is an essential component of amino acids, proteins, enzymes, and chlorophyll, all of which are essential for plant development and metabolism

  • 1.Urea Agricultural Applications:

  • Crop Fertilization: Urea 46% is widely used as a nitrogen fertilizer for various crops, including cereals, oilseeds, vegetables, and fruits. It provides plants with a readily available source of nitrogen, promoting healthy growth, improving crop yield, and enhancing overall productivity.

  • Soil Amendment: Urea can be used as a soil amendment to improve soil fertility and nutrient availability. When applied to the soil, urea undergoes hydrolysis, converting to ammonium and carbonate ions, thus releasing nitrogen that becomes available to plants.

  • Foliar Fertilization: Urea can be applied as a foliar spray on plant leaves. This method allows for rapid nutrient uptake, particularly in cases where there are nutrient deficiencies or when plants require a quick nitrogen boost during critical growth stages.

  • Pasture and Forage Management: Urea is used to enhance the growth and productivity of pasturelands and forage crops. It helps increase the protein content in forage, improving its nutritional value for grazing animals.

  • 2.Urea Industrial Applications:

  • Adhesives and Resins: Urea is a key component in the production of adhesives and resins, such as urea-formaldehyde (UF) resins. UF resins are widely used in the wood industry for manufacturing plywood, particleboard, and other composite wood products.

  • Animal Feed Additive: Urea is sometimes used as a non-protein nitrogen (NPN) source in animal feed formulations. It provides a concentrated source of nitrogen for ruminant animals, aiding in microbial protein synthesis in their rumen.

  • Diesel Exhaust Fluid (DEF): Urea is an essential ingredient in Diesel Exhaust Fluid, also known as AdBlue. DEF is used in selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions from diesel engines.

  • Industrial Cleaning Agents: Urea has applications in the production of cleaning agents, such as dishwashing detergents and household cleaners. It acts as a nitrogen-based compound that helps remove stains and enhances the cleaning properties of these products.

  • Chemical Manufacturing: Urea serves as a raw material in various chemical processes, including the production of other chemicals like melamine, urea-formaldehyde resins, urea- methanol solutions, and more.

Types of Urea 46%:

Prilled Urea: Prilled urea is the most commonly used form of urea. It is produced by forming urea droplets through prilling towers, which solidify into small, spherical granules. Prilled urea is typically white and has a uniform size distribution. It is commonly used in agriculture as a fertilizer.

Granular Urea: Granular urea is similar to prilled urea but has larger granules. It is often used when slower release of nitrogen is desired, as the larger particles break down more gradually in the soil.

Coated Urea: Coated urea is prilled or granular urea that has been coated with a material such as sulfur, polymer, or resin. The coating helps to control the release of nitrogen, providing a slow and controlled release of nutrients over time.

Liquid Urea: Liquid urea is a solution of urea in water. It is commonly used in foliar sprays or as a component in liquid fertilizer formulations. Liquid urea is quickly absorbed by plants and can provide rapid nitrogen uptake.

Urea Formaldehyde (UF): Urea formaldehyde is a compound made by combining urea with formaldehyde. It is used primarily in the production of resins, adhesives, and wood-based composite materials. UF resins have good bonding properties and are commonly used in the woodworking industry.

⇒Note : You can request the required urea analysis certificate from the sales experts of ETETCO Company.

The packaging methods have a significant impact on the overall cost of urea:

1.Bulk Packaging: Bulk packaging is the simplest, most cost-effective, and quickest method, commonly chosen for large quantities and long-distance transportation.
2.Jumbo Bag (1-ton): This type of packaging with various capacities is available for land transportation (trucks, trains) and sea transportation for loading on bulk carriers and containers. It is commonly used for destinations where bulk urea packaging facilities are not available.
3.50 kg Packaging: This type of packaging can be transported by land using trucks and by sea using containers. It is not suitable for bulk carrier transportation.

⇒specially packaging
1.50 Kg in jumbo bag: You can request this type of packaging from the sales experts at Etetco Company on a customized basis, and it will be executed by the company’s implementation teams.
2.Normally, the manufacturer’s brand is printed on the bags. It is possible to package the products in unbranded bags or bags with the buyer’s brand.
