Biochar for the Small Farm or Garden

Biochar from Alex Gray's workshop at Organic Growers School's Spring Conference

Excerpt from the Handout:

Biochar is a highly porous, high carbon material. Much of its utility comes from these two qualities. In soil, the porosity helps retain a good balance of air, moisture, and nutrients, which can help build healthy soil and feed healthy plants. Because biochar is mostly carbon, it is gaining popularity as a carbon sequestration tactic, helping us store carbon in the Earth and fight climate change.
