What is biochar and how is it made?
The Science Behind Biochar
Biochar is primarily composed of carbon, along with various minerals and nutrients that are beneficial for soil health. The pyrolysis process typically occurs at temperatures ranging from 300 to 700 degrees Celsius (572 to 1292 degrees Fahrenheit), which transforms the biomass into a charred substance that retains its structure and nutrients. This stability is what makes biochar an excellent soil amendment, as it can persist in the soil for hundreds to thousands of years.
