Biochar is a type of charcoal produced by heating organic material, such as plant matter, in a low-oxygen environment. This process, known as pyrolysis, transforms the material into a stable form of carbon that can be used to improve soil health. Biochar enhances soil fertility, increases water retention, and helps reduce greenhouse gas emissions. In addition to its agricultural benefits, biochar can also play a role in carbon sequestration. By storing carbon in the soil, it helps mitigate climate change. Researchers are exploring its potential applications in various fields, including agriculture, environmental science, and sustainable development.
