What is Terra Preta?
Terra Preta or dark soil is a unique form of soil which has been created through human activity. This anthropogenic soil has some unique properties; in addition to being incredibly fertile and retaining that fertility for hundreds of years, Terra Preta is also a form of carbon sequestration. Both of these traits have led to widespread interest in Terra Preta around the world, with some people even proposing that it could be used to create a carbon negative fuel, using an energy generation technique called gasification.
