If you still haven’t got an understanding of what biochar is and how it is so important then it might be worth watching this BBC Horizon documentary that puts it in its historical perspective
It is similar to but different from charcoal… made from biomass that has been pyrolyzed within a specific temperature range and set of conditions. The resulting char is pure carbon with all the potentially poisonous volatile substances driven off and combusted and has a gigantic internal surface area. A teaspoon of the material can have a potential internal surface area of 2 acres… creating a perfect habitat for soil microbes..
Together with two friends, local stock farmers we have been developing our techniques for producing the substance. It has remarkable potential in that not only does it increase soil structure, stability and fertility it also helps sequestrate atmospheric carbon into the soil in a very stable form. Last month we were invited to the Hay festival to present our ideas at their ‘Green Dragon’s Den’ forum, sponsored by Unlimited. We had a simple three minute pitch opportunity to impress the competition judges and a keen audience.. an extremely challenging experience! We were one of the runners up and have been listed to receive at least some of the funding we hoped to win. Next up we will be going to the British Biochar Foundation conference in Oxford where we will be having our product and burner scientifically tested as part of a demonstration and competition they are running. We will be trading in future under the name of Garden Planet Biochar.
We hope to be able to sell our product from Pen Dinas in Newtown as perfect complement to the riased beds and plant nursery.. we want to be able to offer a complete growing opportunity for people that keeps us all at the cutting edge in organic growing.
Food security, relocalised food production and low carbon methods of production seem essential strategies for development and often simple practical solutions such as these are overlooked in favour of high tech and high investment options.
