Urea is a high-quality nitrogen fertilizer (theoretical nitrogen content is as high as 46.67%). However, the use of urea is far more than chemical fertilizers and is much broader. According to statistics, there are nearly 20 main applications of urea, covering agriculture, industry, medicine, food, and other fields. It can be said that it is both in the hall and the kitchen.
Urea used for agriculture, among the uses of chemical fertilizers, nitrogen fertilizers are the most widely used and important. Currently, global nitrogen fertilizer use accounts for 60% of total chemical fertilizer use, phosphate fertilizers account for 23%, and potassium fertilizers account for 17%.
International nitrogen fertilizers are based on urea, which is currently the most widely used chemical fertilizer in the world. my country’s nitrogen fertilizer use accounts for 73% of the total chemical fertilizer use, phosphate fertilizers are 22%, and potassium fertilizers are only 5%. At present, domestic nitrogen fertilizer is mainly urea, accounting for 60% of nitrogen fertilizer consumption (that is, urea accounts for about 43.8% of domestic fertilizer consumption).
When urea is applied to the soil, it undergoes a series of chemical transformations. Urease enzymes present in the soil break down urea into ammonia and carbon dioxide. The ammonia is then further converted into ammonium ions, which can be taken up by plant roots. This process helps to enhance crop yields, improve plant vigor, and ensure healthy plant development.
It is widely used for a variety of crops, including cereals, vegetables, fruits, and ornamental plants, making it a cornerstone of modern agricultural practices.
Urea used for industry, urea is mainly used in the production of urea-formaldehyde resin, melamine, and cyanuric acid.Among them, urea and formaldehyde produce urea-formaldehyde resin, which is mainly used to produce wood adhesives and is also used to produce some plastic products, such as power strips, power switches, toilet seats, and other daily necessities.
Additionally, urea can be used in the production of certain pharmaceuticals and pesticides, contributing to the development of drugs and chemicals for crop protection.
Urea used for the medical field, is used in the formulation of certain medications, including diuretics and topical creams for the treatment of various skin conditions. It is also used in diagnostic tests to measure kidney function and to assess the concentration of certain substances in the body. In addition, urea is an important ingredient in the manufacture of certain dental materials.
Urea used for animal feed ,Urea is also widely added to cattle, poultry, and other livestock feed to increase protein content. It helps to maximize animal growth as well as meat and dairy production. Ammoniated urea is preferred for improving the nutritional value of feed. However, take care to use urea supplements with caution and follow recommended guidelines to prevent potential harm to animals.
Urea used for deicing, calcium chloride and urea are the top liquid deicers used to melt snow and ice on winter roads. Urea lowers the melting point of ice to below freezing.
Urea used for cosmetics, as an effective moisturizer, urea is used in a variety of personal care products. It helps retain moisture in the skin and hair. Urea creams and lotions are commonly used to treat dry, cracked feet and elbows. Conditioners also use it to improve hair health.
Urea used for leather industry, Urea is one of the main emollients used in leather tanning and conditioning. It helps treat hides to make them softer and more durable. Tanneries rely on the moisturizing properties of urea to prepare leather for footwear and merchandise production.
In conclusion, urea’s wide range of applications, from fertilizing our fields to reducing vehicle emissions, from enhancing the quality of industrial products to improving our personal care, demonstrates its importance in modern society.
Its versatility and chemical properties continue to make it a valuable compound in multiple industries, and ongoing research and innovation may uncover even more potential uses in the future.
