Chapter 23 – Biochar
Biochar has many potential uses. It can be burned as a fuel, and it has many potential commercial and industrial uses. But, probably the most important potential use for biochar is as a soil amendment. When added to soils, biochar increases the water-holding and nutrient-holding capacity of soils, thereby reducing the need for irrigation and fertilizers.
Chapter 22 – Pyrolysis
Pyrolysis is a term which, though hard to spell, will soon be a household word. Pyrolysis is a process of heating biomass in the absence of oxygen to produce combustible fuel and a byproduct called “biochar.” Biochar is a charcoal-like substance that has many uses. A primary use for biochar, that we will discuss later, is as a soil amendment that increases soil fertility while very effectively sequestering carbon in the soil.
