Incase anyone is interested in the Biochar burn I did the other day here’s how it worked for me (I was not sure what to expect- so feel like it might help others)
I used a biochar kiln, with an inner & outer sleeve. The inner sleeve has holes at the bottom and very top only.
The fuel was riddled woodchip (to stop too small particles blocking airflow)
1 You can see the gasses coming through the top airholes & burning off.
2 flames go pale/invisible
3 quenched char

The biochar will help aerate the soil, add microbiology help with water retention and make a long term store of inert carbon.
The biochar burn stores more carbon than is burnt off, making it a net carbon store despite the fire.

We get woodchip as a waste product from the local tree surgeon.

I also managed to get some willow offcuts from a local basket weaver’s class & will try those next. They will also try making biochar with the rest of their offcuts.

How does it store more carbon than burnt off? where does it get it from?
Show threadHelenaFeb 22
@Asbestos I probably said it badly, so there's not more carbon, just more is stored than is burnt off. I don't know the percentages.

@Hellybootwader
fair enough, I was just curious

@Hellybootwader what is the difference between biochar and charcoal? just that u use it for different things?

i tried looking up the structure of charcoal. not easy to find info.

@barrygoldman1 I read that the biochar charcoal is made at a hotter temp than regular charcoal.
From tge comments I’ve had it sounds like you can also use regular charcoal as long as you add it to a compost heap (or add soil microbes in other ways) to inoculate it first
