Can urea pelletization technology improve agricultural productivity?

Urea is a widely used nitrogen fertilizer in modern agriculture. Due to its high nitrogen content, it is an important plant growth promoter.In order to improve the efficiency and ease of use of urea, the technology of urea powder granulation has been developed. In this article, we will discuss the working principle of urea pelletizing line, its advantages and impact on agricultural production.

Working principle of urea granulation line

• Urea powder granulation is the process of converting fine powder into granular form, which simplifies storage, transportation and application. A granulation line typically includes the following key steps:
• Mixing and preparation:First of all, urea powder is mixed with the necessary additives in the correct proportion to ensure the granules are strong and stable.
• Granulation:The mixed material is passed through a granulator where it is pressed and molded into uniform granules.
• Drying and cooling:Fresh urea granules require drying and cooling to remove excess moisture and increase their hardness.
• Screening and packaging:Finally, after screening to remove substandard granules, the quality urea granules are packaged for sale or direct use.

Advantages of urea granulation

• Improved fertilizer efficiency: Granulated urea can be applied to the soil more evenly, reducing losses and increasing nitrogen use.
• Ease of storage and transportation:Urea granules are easier to store and transport, reducing losses and waste during transportation.
• Reducing environmental pollution:By reducing nitrogen fertilizer losses, urea granules effectively reduce water and air pollution.
• Improved application experience:Granulated urea facilitates mechanized fertilizer application, improving efficiency and accuracy.

Impact of urea pelletizing line on agricultural production

Urea pelletizing line not only improves the efficiency of urea utilization, but also contributes to the sustainable development of agriculture in many ways. By reducing nitrogen fertilizer losses and environmental pollution, urea granulation technology provides important technical support for green agriculture. In addition, with the increasing level of mechanization and automation of agricultural production, the demand for granulated urea will inevitably increase.

The urea granulation line plays an essential role in modern agriculture. Its high fertilizer efficiency, environmental properties and plant growth stimulating effect make it an indispensable part of agricultural production. With the development of technology and increasing market demand, urea granulation technology will continue to grow rapidly, making significant contributions to global food security and sustainable agricultural development.

Enhance fertilizer efficiency and promote crop growth

Increased nitrogen utilization: Urea granulation technology, especially the production of large-grain urea, can significantly improve nitrogen utilization. For example, some studies have shown that the use of large-grain urea in rice paddies has increased the fertilizer efficiency by 10.9% over ordinary urea, and increased rice yields by about 10%. This is because large granular urea dissolves relatively slowly in the soil, nutrient release is smoother, thus reducing the volatilization and leaching of nitrogen, so that the crop can more fully absorb and utilize nitrogen.
Long-lasting fertilizer effect: Granular urea, especially large-grain urea with added slow-release agents or stabilization technology, can extend the fertilizer effect period to cover the full life span of the crop. For example, through the synergistic effect of urease inhibitor and nitrification inhibitor, stabilized granular urea can extend the fertilizer effect period from 60 days to 120 days, realizing “one time fertilizer application, the whole process of guarding”.

Optimize fertilizer application efficiency and reduce labor intensity

Convenient for mechanized fertilization: granular urea particles are uniform, hard, not easy to break, convenient for mechanized fertilization. This greatly improves the fertilization efficiency, reduces labor intensity, suitable for large-scale agricultural production.
Reduce the number of fertilizer application: Because of the long-lasting effect of granular urea, it can reduce the number of fertilizer application, saving labor and time costs. This is especially important for labor shortage or high cost areas.
