Biochar is a type of charcoal that is produced by heating organic material, such as wood, agricultural waste, or other biomass, in the absence of oxygen in a process called pyrolysis. This results in a carbon-rich substance that is stable and has a high surface area.

Biochar has several beneficial properties that make it useful in a variety of applications. Firstly, it has a high porosity, which makes it an effective soil conditioner. When added to soil, it can improve soil structure, enhance water retention, and increase nutrient availability. Biochar can also sequester carbon in the soil, thereby mitigating climate change.

In addition to its use as a soil amendment, biochar has several other applications. It can be used as a filter material to remove contaminants from water or air. It can also be used as a feed supplement for livestock, as it has been shown to improve digestion and reduce emissions of methane, a potent greenhouse gas.

Overall, biochar is a versatile and sustainable material with many potential uses. Its ability to sequester carbon, improve soil fertility, and mitigate environmental pollution makes it an important tool in the fight against climate change and for sustainable agriculture.
