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.

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

Close up photo of the orange flames. The ring of holes around the top of the inner sleeve let gasses out & they burn off. Not much (if any) smoke is coming off the burning dry woodchip. Burn was started with cardboard and eco firelighters from the top.
Still burning but not much visible flames. This is the point you stop the burn- before the charcoal also burns- by pouring lots of water on it to quench it.
A trug with quenched charcoal - there us some water in the bottom of the trug, the liquid run off from a wormery was added to the charcoal to let the microbes colonise the charcoal. Some breaking up of the charcoal chips is still needed.

The article has an unfortunate bias towards industrial scale. Unlike other "carbon capture" char can also be produced (and is) by many small operators. #biochar
