Will it really destroy the soil / affect the crops?

Land is the source of our survival, it not only carries the survival of all plants, but also related to the fundamental development of agriculture and human beings. with the development of agriculture, the emergence of fertilizer has increased the yield of crops and improved the growth rate of plants. but at the same time, it also brings us some problems that can not be ignored.

one

For the environment,

The composition of the material elements in fertilizer is very complex, and it is easy to remain in the soil and water sources, causing the "eutrophication" of the environment to lead to the excessive growth of harmful plants such as algae, and the elements in ordinary chemical fertilizers will also dissolve into the soil and react with them. rise into the atmosphere and pollute the atmospheric environment.

two

For crops,

Ordinary chemical fertilizer will affect the physical structure of the land itself, and the organic structure of the land itself is out of balance, which affects the nutrient cycle of the land, which is very disadvantageous to the later planting and weakens the self-production capacity of the plant. If ordinary chemical fertilizers are used for a long time, the acidity of the soil will increase, and the inorganic compound ions in the soil solution will increase, resulting in the dispersion and hardening of the soil, the crops planted on the land will also be affected, the yield will be reduced, and the planting cost will be increased.

After adding fertilizer to the soil, the concentration in the soil solution passively increases, resulting in a large or small osmotic pressure, which will be affected when the root cells of the plant absorb water from the soil, and what is more, it will cause the soil to absorb the water from it. thus affecting the normal growth of the plant, this is what we often call burning seedlings!

Microbial agent

At present, agriculture is developing rapidly, and it has gradually developed to the direction of "giving priority to [microbial agent] organic fertilizer, supplemented by ordinary chemical fertilizer". The use of single common fertilizer leads to the decline of soil fertility and low crop quality. under the general trend of green and healthy intestines, [microbial agents] gradually occupy the agricultural market and contribute to the development of ecological agriculture because of its high efficiency and environmental protection.

Microbial agents can promote the normal and healthy growth of plants, "no rotting roots", "no insects" and "no drugs"; naturally improve soil fertility, increase production and income, and reduce costs; among them, the highly active beneficial bacteria can fix nitrogen, dissolve phosphorus and potassium, promote the absorption of elements by plants, improve soil quality, promote the absorption of nutrients by plants, and finally increase crop income.

Improve plant resistance and crop quality. In the process of reproduction, beneficial bacteria can release antimicrobial peptides and lactic acid, significantly prevent and reduce all kinds of soil-borne diseases, form a benign microbial environment of crops, and benefit the healthy growth of roots, so as to improve the disease and insect resistance of crops.

Reduce fertilizer pollution and degrade harmful substances. With organic matter as the carrier, a variety of beneficial bacteria are added to effectively degrade various pollutants and prevent crops from absorbing metals and harmful substances.
