I have a small pile of sticks and coconut shells that have accumulated in the garden. As I can’t compost them, I thought I’ll make some biochar to use in the garden. Looking around a bit, I found this low-tech way of making biochar and I think its a good simple way to start.
The allotment garden page where I found this video also has an article about how to charge or activate biochar
I had earlier seen Jon Jondai’s video on the topic. He shows some simple equipment that seems more efficient and does not call for our involvement throughout the process of making biochar. Thats more suitable for my farm.
