How to improve the utilization rate of chemical fertilizer

Chemical fertilizer is a key fertilizer variety in planting and production, and reasonable application of chemical fertilizer can effectively improve the yield of crops. However, after many people apply chemical fertilizer, they will find that the utilization rate of chemical fertilizer is relatively low, and the yield of crops is still not very ideal. Therefore, they all want to improve the utilization rate of chemical fertilizer. So how on earth should we improve the utilization rate of chemical fertilizer? The following editor will give you a brief introduction, let's have a look!

1. Soil testing formula

Soil testing and formula fertilization is one of the effective methods to improve the utilization rate of chemical fertilizer. The purpose of this paper is to detect the content of basic elements needed for the growth of crops such as nitrogen, phosphorus and potassium in the soil, and then carry out reasonable fertilization according to the amount of nutrients needed for the growth of crops. Applying as much as crops need can not only meet the growth and nutrition of crops, but also prevent waste and lead to environmental pollution. Compared with conventional fertilization, soil testing formula can increase the per unit yield of rice, corn and other food crops by about 8%. The utilization rate of chemical fertilizer can also be significantly improved.

2. Balanced fertilization

When planting crops, when we apply chemical fertilizer to them, we should pay attention to the yield of the crops. Because in a certain degree of fertilization, there is a great relationship between crop yield and the utilization rate of chemical fertilizer, which is usually positively correlated. If the amount of fertilizer is increased too much or a single long-term application of the same fertilizer is applied, it is very easy to lead to the imbalance of nutritional environment and reduce yield. So when we apply fertilizer, we don't mean that the more fertilizer we apply, the higher the crop yield. When determining the amount of fertilizer application, the climate and soil conditions should be adjusted reasonably in order to ensure the utilization rate of chemical fertilizer.

3. With the application of organic fertilizer

The application of chemical fertilizer combined with organic fertilizer is an important point in fertilization. Because organic fertilizer, its nutrient elements are very rich, containing a variety of nutrients necessary for crop growth. And it can also improve the soil structure, reduce the loss of chemical fertilizer, and fix chemical fertilizer well, so as to improve the utilization rate of chemical fertilizer. Because of the mixed application of chemical fertilizer and organic fertilizer, the available nutrients in chemical fertilizer can be absorbed and combined by organic fertilizer, and then released again, which can not only improve fertilizer efficiency and fertilizer supply time, but also reduce nutrient consumption.

4. Concentrated and deep implementation

When many people apply chemical fertilizer, the main method of fertilization is to spread fertilizer. In fact, the spread of fertilizer will have a great impact on the utilization rate of chemical fertilizer, so when we apply chemical fertilizer, it is best to concentrate on deep application. For example, with the deep application of nitrogen fertilizer, the utilization rate of nitrogen fertilizer can be increased by about 1 to 5% compared with the application of nitrogen fertilizer. On the other hand, the utilization rate of phosphate fertilizer can be increased by 10%. And if phosphate fertilizer and organic fertilizer are applied as base fertilizer, the utilization rate can be increased by about 35%. However, we still need to choose a suitable fertilization method according to the nature of the soil, for example, sandy soil should be applied with a small amount of fertilizer.

The above is a brief introduction to how to improve the utilization rate of chemical fertilizer. That's all for today's introduction. This article is for reference only. I hope it can help you all.
