When making biochar; until the charcoal is inoculated with some sort of biology it is just empty char. Waiting for microbes to hold. We make our own ferments and work with some amazing natural farmers who are dedicated to providing the most biologically diverse rich microbes to inoculate the char with.
This is a video of Ken a Natural Farmer, Frass Farmer, Biochar maker, and enthusiast doing some biochar inoculations in The Central Valley of California. He is our right hand man for all the different ferments we use to make our biochar. Check out his incredible work at kofrass.com.
