Biochar is a soil additive that can be used to address both soil deterioration and climate change at the same time. Biochar's carbon (C) structure is more stable in soils than that of uncharred organic matter, making it a better soil amendment. Biochar can persist in the soil for hundreds of years if it is created and applied correctly. In terms of both storage time and compatibility with normal tillage, biochar has an advantage over modified native soil C sequestration approaches. Aside from C sequestration, biochar appears to improve soil quality and crop yield. As a result of these and other studies, biochar has been shown to improve soil fertility by increasing the pH in acidic soils, supplying nutrients directly to plants, and increasing the amount of moisture in the soil. Biochar's surface characteristics have a different effect on plant growth than other soil amendments. It's important to know the quality of the biochar before putting it to the soil since some biochars inhibit plant growth, while others enhance plant growth.
