The mechanism of action of biochar in soil improvement
As people have higher and higher requirements for ecological and environmental protection, they are also paying more and more attention to issues such as improving soil fertility, protecting biodiversity, and improving the ecological environment.
As people have higher and higher requirements for ecological and environmental protection, they are also paying more and more attention to issues such as improving soil fertility, protecting biodiversity, and improving the ecological environment. Therefore, biochar, as a new green soil improvement material, has good development prospects. It is worth noting that in future research and application, it is necessary to focus on how to optimize the production process of biochar, and how to improve its efficiency and reduce its impact on the environment. It is expected that in the near future, biochar will become an important ecological resource and will play an important role in the sustainable development of large-scale industrial production and land management.
The porosity and specific surface area of biochar can absorb harmful substances in the air. Adding an appropriate amount of biochar to the soil can improve the texture of the soil, increase soil porosity, and enhance soil permeability and water retention capacity.
(2) Improve soil nutrients
Biochar can not only strongly adsorb toxic substances in the air, but also absorb nutrients in the soil, such as nitrogen, phosphorus, potassium, magnesium and copper. Through the adsorption and release of nutrients, the nutrients in the soil can be better obtained. retention and utilization, thereby increasing the nutrient content of the soil.
（3）romote the reproduction of soil microorganisms
Biochar can absorb microorganisms in the air and nutrients in the soil, providing favorable conditions for the reproduction of soil microorganisms, providing a buffering effect in extreme environments, promoting the development of beneficial microorganisms, and increasing the stability of the soil ecological environment.
(4) Reduce the use of pesticides
As people’s ecological awareness increases, agriculture will pay more and more attention to ecological and environmental issues in practice. Biochar can provide guarantee for agricultural production, reduce the level of chemical fertilizer and pesticide residues, improve the ecological environment of crop roots, increase the resistance of crops to diseases and insect pests, thereby reducing the use of pesticides.
Biochar is a graphic material made from charred degradable waste. It has porous materials, high specific surface area and porosity, and is suitable for soil improvement. Biochar can enhance land fertility and improve crop growth efficiency. It can also reduce chemical residues and absorb harmful substances in the air. Biochar is also of great significance to promoting sustainable development and protecting the ecological environment. Let us work together to develop biochar, a new green ecological resource, and jointly promote the harmonious coexistence between humans and nature.
