[Stoves] [biochar-production] Re: Stoves Digest, Vol 14, Issue 17

[Frank Shields]

Dear Crispin,

 

Not sure I understand your question about "speeding up access to ash". The
ash would be available directly after ashing and long before biomass in the
same soil as long as the ash is not heated to make forms that are not
soluble. And the nutrients from the ash I think a non-point when talking
about the benefits of biochar. I thing the benefits of using biochar is the
changes it makes to soil and soil dynamics and that will be different for
each site and different biochar products. 

 

Regards

Frank

Dear Frank

 

I understand that the silica is what makes rice do so much better - after
all, it needs silica in exactly that form to grow the fastest.

 

You points about the composition of the char are important - particularly if
stoves are supposed to produce something useful.

 

Is there any good reason to suppose that putting the whole mass, the whole
biomass, into the soil, perhaps chipped or ground up? Why would charring it
first do anything except speed up access to ash?

 

Regards

Crispin
