[Stoves] Low temperature vs high temperature charcoal?

[Crispin Pemberton-Pigott]

Dear Dr AD

 

Do you think it is possible that the effect you have created/noted with
sugar fertilisation feeding bacteria that release more from the local
rock/host materials could be the same reason the biofilms are apparently
increasing yields, in at least some soils?

 

Paul's description below bear certain similarities to the effect of making
locally sequestered fertilisers available via the medium of bacterial
hosting.

 

Thanks
Crispin

Josh,

What you say here about biofilm is quite important. Ron Leng and Reg Preston
have studied extensively the formation of biofilm in the rumen of a cow, and
they see biofilm as essential in understanding how biochar works. Biochar
provides surface area and pore structure for the formation of biofilm.
Biochar also provides surface area and pore structure for the growth of AM
fungi, and these fungi secrete large quantities of glomalin into the the
soil. So a healthy soil has both biofilm and glomalin. So the effect of
biochar goes far beyond its immediate physical properties. Have you studied
how biofilm and glomalin might interact?

Paul
