Urea alias carbonyl diamide, carbamide, urea. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen, also known as urea (homophonic with urine). Its chemical formula is CON2H4, CO (NH2) 2 or CN2H4O, and the international generic drug name is Carbamide. Appearance is white crystal or powder. It is a product of animal protein metabolism and is usually used as a nitrogen fertilizer for plants. Urea is synthesized in the liver and is a nitrogen metabolite excreted by mammals. This metabolic process is called the urea cycle. Urea is the first organic compound synthesized by artificial synthesis of inorganic substances.
As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to preserve, easy to use and has little damage to soil. It is a chemical nitrogen fertilizer which is used in a large amount at present. Urea is synthesized from ammonia and carbon dioxide in industry under certain conditions.
Urea storage attention
1. If the urea is improperly stored, it is easy to absorb moisture and agglomerate, which affects the original quality of urea and brings certain economic losses to farmers. This requires farmers to accurately store urea. Urea bags must be kept intact before use. During transportation, they should be handled lightly, rainproof and stored in dry, well ventilated places with temperatures below 20 degrees.
2. If it is stored in large quantities, it should be padded with wooden square about 20 centimeters below, and there should be more than 50 centimeters of space between the upper part and the roof to facilitate ventilation and moisture dissipation, and there should be a passageway between the stack and the stack. In order to facilitate inspection and ventilation. If the urea that has been pouched is not used up, it must be sealed in time to facilitate the use next year.
3. Avoid contact with skin and eyes.
