Robert,
Interesting you mentioned the solid acid nature
of bio-char. I used my prototype gasifier to
make bio-char from wood shavings, hardwood pellets and cocoa shells.
The soil in our area of Northern Illinois
contains a type of limestone which makes the soil very alkaline pH of 8.0+/-.
We added about 10-15% bio-char by volume when we tilled my daughters garden.
We also added the bio-char around the 40 ft
mature white oak which the Ag extension diagnosed
as having chlorosis (lack of iron and nitrogen)
around the perimeter of the tree.
Garden and tree doing extremely well and the
bio-char appears to greatly improve the tilth of the soil too.
Please let us know if you have any papers on the subject.
Best regards,
Bob Abele
Effective Energy
