Thanks to Replanting the Rainforest and EcoInteractive for the heads up on this fascinating video and the following excerpts.
"What is Biochar? Biochar is charcoal that is created by heating biomass (plants) under low oxygen conditions, which sequesters the plants’ carbon, rather than releasing it into the atmosphere. When Biochar is used to amend soil, the resulting Terra Preta sequesters more carbon, increasing its own volume. The activity of friendly microorganisms, called arbuscular mycorrhizal fungi, increases as well. The fungi spread beyond the original carbon, fix additional carbon, stabilize the soil and assist in nutrient uptake by plants. Biochar also improves soil fertility, reducing the need for synthetic fertilizers. It conserves water, prevents erosion and acts as a natural carbon filter for water by removing chemicals from runoff.
Biochar is inert and remains in the soil for thousands of years. It cannot be cut down, burned down, nor is it susceptible to erosion. It is self-renewing.
