Organic Money

Surrounded by shade trees and gardens, about 200 people, a surprising number for such a rural setting, stood around in little knots talking spiritedly about subjects that all came under the heading of Home Economics: local food; natural medicine; home-based alternative energy; home birthing; home schooling, even, get this, home churching.

In this post I’ll have a look at modern day techniques to produce terra preta (often called biochar or agrichar) which have the potential to increase soil fertility, generate energy and sequester carbon all at the same time.
