[Stoves] Biochar Projects for Science Students

[Crispin Pemberton-Pigott]

Dear Kevin

It seems to me there is something excessive about 25% char in the soil. 

Forest fires char entire root systems so it certainly is natural. 

It surprises me that permaculture people would not be in favour of something that is natural and which would benefit certain plant guilds. 

I still find the 'limits shrinkage' in soils argument convincing. Root hairs are fragile.
