Geoff Moxham explains biochar and terra preta

On Saturday the 9th of May, local bio-char expert, Geoff Moxham from The Channon, was in Mullumbimby to do a presentation on biochar (terra preta) and promote its benefits for soil fertility. As part of the Mullumbimby Community Garden open day, Geoff showed how to make bio char in quantities suitable for the average garden patch.

Biochar is made by heating organic waste like wood and plant clippings to high heat in the absence of air. This is also known as pyrolysis. The volatile components escape as gases and can be burned to produce the energy to keep the pyrolysis going. There is also an energy benefit, 20 percent more energy is produced than the process requires, so this can be used for powering plant and machinery etc.
