Definition and characteristics of granular urea

Granular urea is a common nitrogen fertilizer whose main component is urea. Urea is an efficient nitrogen source that releases ammonia through hydrolysis, thereby providing the nitrogen needed by plants and promoting their growth. Compared with other fertilizers, granular urea has the advantages of easy solubility, high nitrogen content and convenient application, making it an indispensable fertilizer choice in modern agriculture.

The importance of granular urea in modern agriculture

In current agricultural production, improving crop yield and quality is the main goal of farmers. Granular urea can effectively increase the nitrogen nutrient level of the soil, promote the growth and development of crops, and significantly increase yields. In addition, appropriate application of granular urea can help improve soil structure, enhance soil water retention capacity and permeability, thereby improving soil health.

How to apply granular urea

Granular urea can be applied in a variety of ways, with common methods including basal application, top dressing and foliar spraying. Among them, basal fertilization is to mix granular urea directly into the soil during soil cultivation; topdressing is to apply nitrogen fertilizer according to the crop growth stage during crop growth; foliar spraying is to spray urea solution on the crop leaves, quickly Supplement their nitrogen needs.

Criteria for selecting high-quality granular urea

When choosing granular urea, farmers should pay attention to the following points:
- **Particle Uniformity**: The particles of high-quality granular urea should be uniform and complete to avoid powdery or agglomerated phenomena.
- **Nitrogen content**: Products with high nitrogen content should be selected to improve the fertilization effect.
- **Solubility**: High-quality granular urea has a high solubility and can be quickly absorbed by plants.

Summarize

All in all, granular urea is a fertilizer of great significance to agricultural production. It not only enhances the nutritional value of the soil but also promotes healthy crop growth. Therefore, the correct use of granular urea plays an important role in improving agricultural productivity and ensuring farmers' income. Understanding the characteristics and application methods of granular urea and rationally selecting high-quality fertilizers will help farmers achieve higher production goals.
