How does Biochar work? Water
Remnant cell structures become nanotubes and buckeyballs that hold water and minerals, acting as if a coral reef in the soil.
Scientist Brian Dougherty and colleagues say biochar is like a sponge. “Biochar provides a structure with lots of empty pore space,” he says. “The outer surface may appear small but the interior surface area is absolutely massive. A few ounces of biochar can have an internal surface area the size of a football field. There is a lot of potential there for holding on to water and nutrients.”
