Product Features
1. Low dust content: granular urea has a low dust content, which helps to reduce dust pollution during fertilization and protect the environment.
2. High compressive strength: granular urea has a high compressive strength, which makes it difficult to break and agglomerate during transportation and storage, and is suitable for mechanized fertilization.
3. Moderate dissolution rate: The dissolution rate in water is slightly slower, which allows it to sink deeper into the soil when applied in paddy fields, reducing volatilization losses and improving fertilizer efficiency.
4. Low biuret content: Due to different processing techniques, the biuret content in granular urea is lower, which is more beneficial to crop growth.
5. Long-lasting fertilizer effect: granular urea has a smaller specific surface area and a slower dissolution rate, but a higher fertilizer effect and a longer onset time, making the fertilizer effect more lasting and effective.
Application&Fertilization Methods
Suitable Crops
Granular urea is suitable for various crops, especially for crops with longer growth cycles and higher fertilizer requirements, where the effect is more significant. Including but not limited to:
1. Corn: Corn is one of the main grain crops in Europe, with a long growth cycle and requiring a large amount of nitrogen. Granular urea can continuously provide nutrients for corn, ensuring its healthy growth and high yield and quality.
2. Wheat: Wheat is also an important cereal crop that requires a continuous supply of nitrogen during its growth cycle. Granular urea can better provide nutrients for wheat, promoting its growth and development.
3. Rice: Rice has a long growth cycle and requires a large amount of nitrogen. Granular urea can continuously provide nutrients for rice, ensuring its healthy growth and high yield and quality.
Fertilization Methods
Granular urea is suitable for use as base fertilizer and should not be applied as topdressing or flushing fertilizer. Its particle size matches that of diammonium phosphate and can be used as a material for blending compound fertilizers. The dissolution rate of granular urea is slightly slower, making it suitable for use as a base fertilizer, which can continuously provide nutrients for crops, reduce the frequency of fertilization, and lower labor intensity and costs.
