Biochar

Biochar (or horticultural charcoal) should not be used alone without a source of organic material, so we are combining it in a dry mixture with VermiCompost. We call the blend BioPreta.
Our BioPreta products are for sale at: BioPretaSuperSoil

Then, brewing a "tea" with BioPreta gives biochar the immediate short-term inoculation of microorganisms needed to convert the organic material to "inorganic soluble salts" required by plant roots for immediate absorption.

I'm performing at Farmers Markets, festivals and various other places where I am invited to demonstrate my passion. Kids are lured to my booth by the spinning of the VermiHarvester and while they learn about vermiculture, their parents get drawn into a discussion of sustainability, and converting organic waste into food.
