Chemical properties and production process of urea

Urea (chemical formula CO(NH₂)₂) is a common and efficient nitrogen fertilizer. Due to its high nitrogen content (approximately 46%), urea can quickly break down and release nitrogen for easy uptake and utilization by crops. Urea has good water solubility and can quickly mix with soil to improve soil fertility.

In terms of production technology, urea is mainly produced through the synthesis reaction of ammonia and carbon dioxide. This process is carried out under high temperature and high pressure conditions, with high production efficiency and relatively low cost. At present, the annual global urea production has reached more than 200 million tons, most of which is used in the agricultural field.

The application effect of urea in agriculture

Urea is used in agriculture to effectively promote crop growth and significantly increase yields. For example, in actual farm applications, the application of urea to major food crops such as corn, rice, and wheat has a significant yield increase effect. In a field trial, rice fields treated with urea increased yields by 15% compared to unfertilized control fields. This effect makes urea the first choice for farmers and agricultural producers.

Market demand trends and practical suggestions

In recent years, with the increase in global population and demand for food, the market demand for urea has also increased steadily. According to market survey data, it is expected that global demand for urea will continue to grow at an average annual growth rate of approximately 2% by 2025. For farmers and agricultural producers, it is extremely important to understand how to use urea scientifically and rationally.

Here are some practical suggestions for using urea:

• Reasonable application amount: According to soil fertility and crop type, the application amount of urea should be reasonably determined to avoid excessive fertilization.
• Fertilizer application time: Applying urea during the peak period of crop fertilizer demand (such as early growth or flowering stage) has the best effect.
• Fertilization methods: Use deep fertilization, strip fertilization and other methods to improve the utilization rate of urea and reduce nitrogen loss.
• Environmental protection: Avoid fertilizing during the rainy season or during excessive irrigation to reduce the pollution of water sources caused by urea loss.

👩‍🌾 Tips: Before applying urea, it is recommended to conduct a soil test to determine the nitrogen content in the soil in order to formulate a scientific and reasonable fertilization plan.

In summary, urea, as an efficient nitrogen fertilizer, can significantly promote crop growth and increase agricultural yields. The scientific and reasonable use of urea can not only maximize its effect, but also achieve sustainable agricultural production.
