EP54 Biochar

When it comes to soil amendments, charcoal is probably not the first thing that comes to mind. But if you really think about it, charcoal is carbon that’s been locked up in the same way that coal is carbon, perfectly sequestered. There’s a catch though – you can’t burn it. But if we can’t burn it, how do we activate the carbon in biochar?

In this episode, Rob Lavoie of AirTerra helps us understand how to unlock that carbon and feed those hungry little soil microbes that feed us.
