Hi Larson,
Thanks for the information. The reason that I am asking for this possibility, is to use Biochar as a carrier for fertilizer containing antagonism micro-organisms, since Trichoderma likes very much cellulose, and other carrier that I was in touched to are made primarily by cellulose.
Where do you find Biochar producers in Vietnam, and are their Biochar well characterized? I live in the South of the country, and have known Long An province (done by Ecofarm, from corn cob) has it, but still experimenting it
Bom
