We’ve discussed the basics of terra preta soil – the most fertile soil in the world – in two previous blog posts. As I explained in the earlier blog posts, scientists are racing to unlock the secrets of terra preta soil and the role that biochar plays. New biochar research is coming out that may hold the keys to restoring land degraded from years of industrial chemical farming. If the claims made in the following videos turn out to be true then that means we now know how to develop permanent soil fertility. In addition, you can heat your home and greenhouse from waste heat given off during the biochar making process. This BBC documentary — The Secret Of Eldorado – TERRA PRETA — explains why terra preta is more valuable than gold. Test trials have shown terra preta can produce 880% increase in plant yields.
