Is abuse of chemical products harmful? How to fix it?

Chemical fertilizers are widely used by growers, and it is even an important determinant of crop productivity. However, the use of chemical fertilizers in a widespread manner for a long time has made the soil infertile, degraded, seriously affecting the environment. In addition, the harmful effects must include:

• Dangerous and toxic: Some chemical fertilizers contain nitrate compounds, so the amount of nitrate in vegetables or foods can cause the conversion of hemoglobin in the blood to methemoglobin, this metabolism happens more strongly and more in humans. young, causing illness and death.

• Increasing susceptibility of plants to diseases: Many plant diseases are controlled by the microorganisms growing around the root zone. The lack of these microorganisms and some necessary micro-elements is quite common in areas where chemical fertilizers are regularly applied. As a result, the roots are surrounded by too many certain elements and cannot absorb other essential elements, thus weakening the tree due to nutrient imbalance and being susceptible to tons of diseases.
  

• Kill microorganisms: When chemical fertilizers are used for a long time, the acids formed will destroy the fertile organic humus generated by the decay of dead soil organisms. Thus, this layer of surface solids prevents water from seeping in, and at the same time does not allow water below to infiltrate to escape steam. The soil layer below becomes clogged and acidic. In this anoxic and acidic soil layer, the microorganisms density changes and can die.

• Prevent the absorption of essential nutrients: The humus particles will be attractive to nutritional elements such as nitrogen, phosphorus, potassium, and other metal elements. Chemical fertilizers applied to the soil year after year will cause a fundamental change in the structure of organic humus particles. When there are too many particles around the humus particles, the root system's root hair is eaten by one element and is no longer able to absorb the other minerals that the plant really needs.

How to fix

• Use a lot of organic fertilizer
• Limit the use of pesticides if they are not needed
• Apply lime to improve soil before and after each crop
• Crop rotation
