If you change your soil, you can change everything

Everything—from how we treat the planet, to how we produce food, to how we treat ourselves—starts from our soil. We give you permission to try something dating back to 450BC, biochar.


A 100,000 strong population in the Amazon Basin in Brazil were composting and burning their waste in large dug out pits. The cycle of burying and burning their organic waste over time resulted in rich fertile soil, called Terra Preta. The discovery of this soil by ecologists in the 1980s has developed into a field of research aiming to uncover the history, properties and applications of Terra Preta.

Biochar Kiln to make biochar at home

Firstly, I should say I am loving the ability to make biochar and so speedily.

Firstly I should say that I am loving having the ability to make biochar and so speedily. I used the product of my first firing to prep an area of soil to plant up some sprouts for Christmas. That was a few weeks ago now and the plants have become scarily huge and triffid-like and trying now to break out of their butterfly netting. I put this down to a magic mix of my home made compost mixed with biochar! A big plus for biochar I feel.
