[Stoves] Request for biochar results. Re: [biochar] [biochar-stoves] A review of chronological development in cookstove assessment methods: Challenges and way forward

[IPC]

Love it!

“The urine-biochar treatment led to a pumpkin yield of 82.6 t·ha−1, an increase of more than 300% compared

with the treatment where only urine was applied, and an 85% increase compared with the biochar-only treatment.”

 

First, there seemed to be no control, i.e. no test where there was no change in soil treatment.  Second, biochar only seemed pretty damned useless.  

 

Is this really the best that can presently be said for proper agricultural research into biochar? As an ex-farmer, I would say there is a LOT of research still to be done!

            Our disagreement in this thread is with people who are convinced stoves shouldn’t be producing charcoal - so I am keeping the stoves list (which you may have intended to drop).  They are the ones creating problems for the biochar community (problems including wasting time).

 

            The list “biochar-international” will have about 1000 papers in 2015 (less than 100 when the term biochar was adopted in 2007).  Most of these are on effects in soil.  Virtually none on sequestration value - and only a small number on stoves.

 

            I include the one which has given the largest impact (that I am aware of) on improved productivity.  Lots of other references there.  Hans-Peter does good work .- and his place of publication is free - with a lot more useful data in this and his other free papers
