With developed pore structure and strong adsorption capacity, activated carbon is widely used in agriculture, such as as fertilizer additives, greenhouse cultivation and soil remediation.
Activated Carbon Role as Fertilizer Additives
Coal based activated carbon is made from bituminous and anthracite coal by steam activation, and has a rich microporous structure and a large surface area, enabling it to be used as a fertilizer additive and to play an important role in soil improvement.
Improvement of soil structure
Activated carbon added to the soil increases the organic matter content of the soil, which enhances the stability of the soil structure and thus improves soil aeration and water permeability. Improved soil structure helps microbial root growth and development, and improves soil fertility.
Increase microbial activity
Activated carbon can provide a favorable environment for microbial growth. The surface of activated carbon has a rich microporous structure, which can serve as a habitat and protective layer for microorganisms.

Harmful substances adsorption
Activated carbon has a strong adsorption capacity and can adsorb harmful substances in the soil, such as heavy metals and pesticide residues, reducing their effects on microorganisms and plants.
Nutrient absorption
The addition of activated charcoal keeps the soil loose and loosened, which facilitates plant root growth and nutrient uptake, as well as aids in water infiltration and root growth, improving plant growth efficiency.
When condensate passes through the activated carbon bed, organic pollutants are adsorbed onto the surface of the activated carbon, thus purifying the water quality. As the activated carbon is used, it becomes saturated with adsorption and needs to be replaced or regenerated on a regular basis to ensure continued effective condensate treatment.
Improve fertilizer utilization
Activated carbon adsorbs and stabilizes the nutrients in fertilizers, prevents their loss and volatilization in the soil, retards their release to provide a continuous source of nutrients for the plants, helps to increase the utilization rate of fertilizers, and reduces the loss of nutrients.
Regulate soil pH
Activated carbon can help regulate the acidity and alkalinity of the soil to keep the soil within the appropriate pH range, which is favorable for plants to absorb nutrients and promote their growth and development.
Huamei Coal Based Activated Carbon
Good Solutions to Fertilizer Additives
HMG-BC™ Coal Granular Activated Carbon and HMP-B™ Coal Powdered Activated Carbon are both preferred as fertilizer additives. Huamei activated carbon factory is located in Ningxia, where there are abundant coal mine resources. We make full use of the local coal mine resources and adopts advanced production technology to produce high quality activated carbon.
