Geologic and biologic carbon sequestration of excess carbon dioxide in the atmosphere emitted by human activities.Biochar can be landfilled, used as a soil improver or burned using carbon capture and storage.
The soil carbon sequestration is the long-term storage of carbon in soil which could well be accomplished by the application of biochar as a soil amendment. Biochar (BC) is a fine grained, highly carbonaceous, pyrolysed (low temperature) product of biomass.
For soil use, biochar particle size must be reduced. From the view of microbes, powdered biochar is most effective and efficient as a culture media.In the focus on biochar as carbon for sequestration, minerals are overlooked.
When returned to the soil, biochar creates a stable, long-term carbon sink. "Biochar also has been shown to improve the structure and fertility of soils, to enhance the retention and efficiency of fertilizers as well as to improve the productivity of soil," said Lehmann.
Input of biochar into soil is considered as an efficient technology for carbon sequestration. This work is aimed to explore if the extra sorption of carbon dioxide (CO2) exists in the biochar-amended soil, which has not yet received attention.
As we can see from the illustration, Carbon Sequestration In Soil Using Biochar has many fascinating aspects to explore.
Biochar, a carbon (C)-rich material obtained from the thermochemical conversion of biomass under oxygen-limited environments, has been proposed as one of the most promising materials for C sequestration and climate mitigation in soil.
