Common misunderstandings in the use of chemical fertilizer

Chemical fertilizer is an indispensable fertilizer for many people in planting and production. And chemical fertilizers are indeed very beneficial to increase crop yields. However, there are many misunderstandings in the use of chemical fertilizers and many people's understanding of chemical fertilizers. So what are the specific misunderstandings in the use of chemical fertilizer? Today, the editor has brought you common misunderstandings in the use of chemical fertilizer. Let's take a look at it.

1. There is no need to apply chemical fertilizer if there is nitrogen, phosphorus and potassium in the soil.

The first misunderstanding of using chemical fertilizer is that many people think that if there is nitrogen, phosphorus and potassium in the natural environment, they do not need to use chemical fertilizer. In fact, when growing crops, although there are some nutrients naturally in the surrounding environment, but these are not comprehensive. At the same time, it is not possible to provide crops with all the materials they need. If we rely only on natural soil, it will basically take decades of accumulation to ensure that the organic matter in the soil can meet all the nutritional needs for crop growth. And the growth of crops in one season can consume the nutrients that the soil has accumulated for decades. Therefore, the application of chemical fertilizer is the key measure to supplement soil nutrition.

2. Chemical fertilizer organic fertilizer has the same nutrition, and organic fertilizer can be used completely.

In planting and production, if only organic fertilizer is used, it is basically unable to meet the nutritional needs of crop growth. Therefore, it is difficult to achieve the goal of high crop yield, and the yield can only be increased by increasing the planting area. In addition, the proportion of nitrogen, phosphorus and potassium in organic fertilizer is difficult to balance. Therefore, the application of chemical fertilizer is the key measure to ensure balanced nutrition. And the effect of the combined application of organic fertilizer and chemical fertilizer is very good, so we should pay attention to the combined application when applying fertilizer.

3. Water eutrophication caused by chemical fertilizer

If chemical fertilizer is not used properly, it will indeed cause pollution to the environment. However, although the leaching of chemical fertilizer will lead to water pollution, there are actually many causes of water pollution. A professional data survey shows that the water pollution caused by urban sewage discharge is far more serious than the loss of chemical fertilizer. And whether it is organic fertilizer or chemical fertilizer, it is possible to leach out and cause water pollution. Therefore, when we apply chemical fertilizer, we should pay attention to control the fertilization time and the amount of nitrogen, phosphorus, potassium and other fertilizers, and apply fertilizer scientifically in order to effectively control the loss of chemical fertilizer.

4. Chemical fertilizer is harmful to environment and human body.

Chemical fertilizer actually contains substances that can be absorbed by plants and is a key fertilizer to provide nutrients for crops. And the nutrient elements such as nitrogen, potassium, phosphorus and sulfur in chemical fertilizer are actually the same as those in the human body and food. Generally speaking, chemical fertilizer is non-toxic, and the nutrient elements in chemical fertilizer are obtained from nature and belong to natural substances. Chemical fertilizers simply convert these substances into substances that can be absorbed by crops. The main reason for the harm of chemical fertilizer to the environment and human body is due to the excessive use of chemical fertilizer and the single partial application of chemical fertilizer. Therefore, as long as there is a reasonable method of fertilization, it will not cause harm to the human body and the environment.

The above is a brief introduction to the common misunderstandings in the use of chemical fertilizer. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
