Urea granular fertilizer is a commonly used nitrogen fertilizer in agriculture. Its active ingredient is urea, which has the characteristics of high nitrogen content and rapid dissolution. It can promote crop growth, increase yield and improve soil fertility.
The first step to correctly use urea granular fertilizer is to choose the appropriate application time and application amount. Excessive fertilization will cause environmental pollution, so it is necessary to apply fertilizer reasonably according to the growth needs of crops.
Urea should be applied at key stages of crop growth, such as tillering and jointing. At this time, the crop's demand for nitrogen increases, and the application of urea granular fertilizer can fully meet its growth needs.
It is also very important to conduct soil testing before fertilization. Through testing, you can understand the nitrogen content in the soil, thereby ensuring a reasonable supply of nitrogen and achieving efficient fertilization results.
It is recommended to alternate urea granules with other fertilizers to improve fertilizer utilization and overall crop output. For example, combining organic fertilizers with phosphorus and potassium fertilizers can help improve soil structure and provide more nutrients.
In short, the correct use of urea granular fertilizer can greatly improve the yield and quality of crops. In the process of fertilization, the reasonable selection of application time and application amount, and the use of other fertilizers in combination can achieve the best fertilization effect and promote the sustainable development of agriculture.
