I can understand that if you bury charcoal (in old empty coal mines would be good ) then you are definitely removing carbon permanently. What I'm not clear on is that surely if you bury it in the soil and it makes crops grow faster, aren't you just turning the charcoal back into living plant tissue? Great for farming which gets higher yields but surely in terms of carbon, you are just ...

Biochar, Charcoal remains in TP soils runs 500 to 7,000 years old. It is a motel for all the weebeast, open bar and a full fridge, waste and water system. In this very highrise community all the metrics of soil fertility increase. One gram of charcoal cooked to 650 C Has a surface area of 400 m2 (for soil microbes & fungus to live on), now for conversion fun: One ton of charcoal ...

Thanks, that makes sense. So why isn't it used more widely? i/ Is there a shortage of charcoal or some other limit in the supply chain? Is it more valuable as a fuel? ii/ Do people just not know about it? Horticultural charcoal is used by gardeners and nurseries iii/ Is it more expensive for the same benefit as modern chemical fertilisers? iv/ Does it not provide as much benefit on ...

In nature, some of the less burned (incompletely burned) roots and above surface woody growth gradually gets into the soil, for the aforesaid micro-organism niche. Necessary for truly healthy soils, along with the minerals from the more completely burned ash in natural fires. The fast moving fires of nature would not kill down too deep so the micro-organisms and worms would rebound, to take ...

"Charcoal is expensive because it is wood heated in a low oxygen atmosphere, and the gas that comes off is not enough for all the heat needed." Not true, modern closed-loop fluidic bed reactors use only a small fraction of biomass energy to start the reaction which is then self maintaining. Depending upon how the reactor is fine tuned and type of feedstock, every ton of biomass will ...
