How to Deal with Fertilizer Damage Caused by Excessive Use of Chemical Fertilizers Scientifically

Excessive use of chemical fertilizers will not only affect the yield and quality of crops, but also exacerbate ecological pollution, and even threaten the safety of food, in short, the final damage is our own. Therefore, excessive use of chemical fertilizers must do the following four scientific points.

First, increase publicity.
This is the most basic aspect, many people are often the lack of knowledge, and always rely on experience, often easy to cause excessive use of fertilizer. Although the awareness of farmers has been improved in recent years, but the publicity is still far from enough, to vigorously promote scientific knowledge of fertilization and the dangers of excessive use of chemical fertilizers, through the network, the media, science and technology to the countryside and other measures, so that more farmers understand the importance of scientific fertilization.

Second, the promotion of soil testing and fertilization.
The promotion of soil testing and fertilizer application is to help farmers understand the soil testing formula, to make detailed deconstruction of soil composition in different areas and different plots, what crops are suitable for the land, and how to balance the content and ratio of carbon, phosphorus and potassium elements to achieve balanced fertilization, so as to promote high crop yield. Of course, this work is relatively complex and requires the integrated efforts of multiple departments.

Third, increase the proportion of organic fertilizer.
The characteristics of organic fertilizer are relatively obvious, with a full range of nutrients, fertilizer efficiency, non-polluting, improve the physical and chemical properties of the soil, increase the soil's ability to retain water and fertilizer, improve the quality and yield of agricultural products, but pay attention to one thing, before application to be rotten.

Fourth, pay attention to the application of trace elements.
Many farmers in planting crops, often after the application of the base fertilizer, no longer chase fertilizer, that the base fertilizer is applied to the nitrogen, phosphorus and potassium compound fertilizer, its elements have been in place, but carbon, phosphorus and potassium are the main trace elements. In fact, the application of micronutrients (manganese, zinc, iron, etc.) is also critical to allow a balanced supply of nutrients as a way to improve crop yields.
