It’s Freaky Friday here at the blog, and that means History! Though I usually look for Diesel era history to post on Fridays, I’m taking things back a little further today because all week I’ve been out with my hands in that rich black gold. No, not oil. I’m talking dirt.

There’s this stuff called Terra Preta (it’s Portuguese for “dark earth”). Found originally in the Amazon, it’s a by-product of ancient Amazon civilizations. It’s composed of charcoal created from the slow burn of trees or other woody substances, kitchen scraps, and what amounts to ancient household trash. And it is dirt’s Wonder Drug.
