Appearance: White granular structure
Chemical Formula: (NH2)2CO -- CH4N2O
Packaging Type: 50 Kg bags
Areas of Use:
Urea, also known as carbamide, is an organic compound with the chemical formula CO (NH2) 2. This amide has two -NH2 groups combined with a carbonyl (C = O) functional group.
Urea has an important role in the metabolism of nitrogen-containing compounds and is the main nitrogen-containing substance in mammalian urine. It is a colorless, odorless solid and is highly soluble in water and almost non-toxic. Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most importantly in nitrogen excretion. The liver forms it by combining two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in the urea cycle. Urea is widely used in fertilizers as a nitrogen source and is an important raw material for the chemical industry.
Urea can be produced in a major conceptual milestone in chemistry. It is the first time that a substance is known to be a byproduct of life, contradicting the widely held doctrine of life that a substance can be synthesized in a laboratory without a biological starting material.
Uses
Urea is the raw material for producing two main classes of materials: urea-formaldehyde resins and urea-melamine-formaldehyde, which is used in marine plywood.
Urea can be used to create urea nitrate, a high explosive used industrially and as part of some improvised explosive devices. It is a stabilizer in nitrocellulose explosives.
Over 90% of the world's industrial urea production is destined for use as nitrogen-releasing fertilizers.
Urea has the highest nitrogen content of commonly used nitrogenous fertilizers. Therefore, it has the lowest transportation cost per unit of nitrogenous nutrient.
Due to the high nitrogen concentration in urea, it is very important to ensure even distribution. Application equipment must be correctly calibrated and used correctly.
Drilling should not be done in contact with or near the seed due to the risk of germination damage.
Urea is dissolved in water as a spray or through irrigation systems.
In cereal and cotton crops, urea is often applied during the final planting before planting. In high rainfall areas and sandy soils (where nitrogen can be lost through leaching) and when good rain is expected, urea can be side-dressed or top-dressed throughout the growing season. It is also popular for top-dressing, pasture and forage crops. In sugar cane cultivation, urea is side-dressed after planting and applied to each tahini plant.
In irrigated crops, urea can be applied dry to the soil or dissolved and applied via irrigation water. Urea dissolves in water by its own weight, but becomes increasingly difficult to dissolve as the concentration increases. If urea is dissolved in water, it is endothermic; the solution temperature drops as the urea dissolves.
