Properties of urea
Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 �¢?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present.
Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �?�³�¯�¼? The melting point is 132.7 �¢??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 �¢?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 �¢??�¯�½? 160 �¢?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 �¢??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption.
Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces.
The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made.

Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystal and one of the simplest organic compounds. It is the metabolic decomposition of protein in mammals and some fish. The main nitrogen-containing end product is also the nitrogen fertilizer with the highest nitrogen content.
As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, easy to use, and has little damage to the soil. It is a chemical nitrogen fertilizer that is currently used in a large amount. In industry, ammonia and carbon dioxide are used to synthesize urea under certain conditions.
Agricultural applications:
Urea is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects.
Animal husbandry can be used as feed for ruminants. However, excessively high temperature in granulation will produce a small amount of biuret, also known as biuret, which has an inhibitory effect on crops.
my country stipulates that the content of urea biuret used in fertilizers should be less than 0.5%. When the biuret content exceeds 1%, seed fertilizer, seedling fertilizer and foliar fertilizer cannot be used, and the urea content in other application periods should not be too much or too concentrated.
Urea is a solid, granular fertilizer known for its high nitrogen concentration. In the case of Urea 46%, the product contains 46% nitrogen by weight. Nitrogen is a critical nutrient for plant growth and is essential for various processes, including leaf development, protein synthesis, and overall plant vigor.
