Agricultural application value of urea granules

Urea granules are widely used in agriculture as an efficient nitrogen fertilizer. Its high nitrogen content can effectively promote plant growth. However, different crops have different responses to urea particles. Therefore, accurately grasping the application effect is the key to improving agricultural production efficiency.

Comparison of application effects of urea granules in major crops

This section will start with the three main crops of wheat, corn and soybeans, and systematically discuss the application effect of urea granules.

1. Wheat

According to research data, the application of urea granules during the growth period of wheat can significantly increase the leaf area index and dry matter accumulation of wheat, thereby promoting yield improvement. It is recommended to apply it after wheat sowing and during the middle and late growth period to achieve the best results.

2. Corn

Corn has a large demand for nitrogen, and the application of urea granules can effectively increase the growth rate of corn. Research has proven that applying urea during the jointing stage of corn can increase yield by 15%-20% while maintaining appropriate moisture and soil conditions.

3. Soybeans

Although soybeans are a nitrogen-fixing crop, appropriate application of urea granules can still increase their yields. Experiments have shown that applying urea during the initial flowering stage of soybeans can promote the formation of pods and increase yields.

Key influencing factors of application effect

Factors that affect the application effect of urea granules include fertilization timing, fertilizer amount and crop growth stage, etc.:

• Timing of fertilization: Proper timing of fertilization can maximize the utilization of nitrogen fertilizer.
• Fertilizer dosage: Too much or too little fertilizer will affect the growth of crops, so it needs to be adjusted according to soil fertility and crop fertilizer requirements.
• Crop growth stage: Different crops have different demands for nitrogen fertilizer at different stages of growth, and should be applied reasonably according to specific conditions.

Conclusion

By comparing the application effects of urea granules on different crops, it can be seen that scientific and reasonable fertilization methods can significantly improve crop production efficiency and contribute to the sustainable development of agriculture. We hope this article can provide practical reference and guidance for agricultural practitioners.
