Description
Black Soil Magic is a fabulous and sustainable soil amendment that acts like a sponge to hold nutrients, microbes, and water. BSM reduces leaching and, once made, captures carbon, removing it from the carbon cycle and stopping CO2 release into the atmosphere for years. It is simple to produce from waste products on your plot! Here is a simple, step-by-step guide to making Black Soil Magic (biochar) for free in small batches in the allotment, garden or small-holding, using an open firepit and/or a range of DIY, simple-to-source, inexpensive retorts or kilns. The scope of this publication covers open pyrolysis of bulk secondary feedstocks with a flame curtain alongside the decomposition of finer primary feedstocks within a Flexi-Tube or small kilns made from baked bean cans shoved together or old paint tins. The colour pictures showing a firepit, feedstock, pyrolysis and crushing of biochar were all taken in Lincolnshire, UK.
