How did 20 million people in the Amazon manage to feed themselves? - it's all in the SOIL -
There are companies that sell supposed terra preta. I looked for it after seeing Graham’s appearance on Rogan but my guess is most if not all companies marketing it are full of shit. It sounds like terra preta may be soil from Amazonian trash heaps kinda like compost heaps. I have also been down the bio char rabbit hole. I am planning on making some bio char(essentially crushed up charcoal that has been burnt in an oxygen deprived fire) and mixing it into my compost heap. I think that is the closest approximation we can get to true terra preta but without clean, unpolluted rain and truly organic compost material, it will be just an approximation.
