Biochar is a carbon-rich, porous material that is produced through the process of pyrolysis, which involves heating organic matter (such as agricultural waste, forestry residues, or municipal waste) in the absence of oxygen. Biochar is a form of carbon sequestration, as the carbon in the organic matter is stabilized and held in the soil for hundreds to thousands of years.
Biochar has several benefits for soil health and plant growth, including:
Biochar can be used in a variety of agricultural and horticultural applications, including as a soil amendment, as a component of growing media, and as a substrate for mushroom cultivation. It is also being researched for its potential in mitigating climate change and improving soil and water quality in a range of other applications.
