Anyone with a smart phone or tablet can download books on biochar I did they even give you instructions on how to build the kilns and how to do the activating of it
Did I missed the part where the char was charged with good microbes? If you add pure char to soil it would take time to absorb nutrients before it could be of benefit to the crops.
This is not how you make Biochar! Most of the wood was burned up. Need a 55 gal barrel, and a 30 gallon barrel. Put the wood in the 30, Lay the 55 on its side. Slide the open end of the thirty, inside the fifty. Set it up. Put wood on the sides of the 30. Then light it. Put the chimney back on the 55. The finished product needs to be inoculated before it is spread , and mixed into the soil.
crop residues are often burned in the field for no use at all. We also used rice husks in Ghana. If there is a cooking value for the corn cobs they would better be used for cooking instead of fire wood.
There is no difference between charcoal and biochar. Charcoal used as soil amendment was named biochar at the World Congress of Soil Science in Philadelphia 2006. Further, this type of feedstock makes charcoal with very low quality.
