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. <o:p></o:p></span></font></p>
