Everyone who has spent time on homesteader youtube has heard about biochar, but what exactly is it, is it actually that good for your soil, and most importantly, do you actually need it?

In this episode, we learn the differences between char, biochar, and discuss some soil chemistry to see if farmer Joe on youtube has been lying to you the whole time!
