Terra Preta Project

We created, built (handmade) and experienced diverse items and methods for the production of Terra Preta:

pyrolysis stove, pottery bokashi bin, Indigenous Microorganism, composting.

Terra Preta, meaning “Black Earth” in Portuguese, is a soil building technique developed by ancient Amazonian civilizations at least 7000 years ago as a solution to permanently solve the problems of poor soil fertility.
The soils contain high amounts of char-wood (also referred to as bio-char). Char-wood is basically a form of charcoal produced by burning wood or agricultural residues in an environment very low in oxygen. This process is called pyrolysis. (Permaculture Research Institute)
