Terra Preta

The terra preta are some seriously fertile soils in the Amazon Basin. They are a man-made agricultural wonder, made even more amazing by the fact that these soils were created about 9 to 10 thousand years ago.

There is a great BBC documentary called The Secret of El Dorado which discusses the terra preta soils. If you can find the video online, via YouTube or Google Video, it's worth the watch.

Another amazing thing is that we have no idea how they actually did it. Todays scientists are trying to replicate the terra preta using biochar.

I hope you become as passionate as I have to spreading the news of the multiple solutions Terra Preta (TP)soils provides and post it to your cite.
I'm sort of a TP cub reporter for the list, most of my post are on news and collaborative efforts caught in my Google filters., my lobbying efforts with writers, companies, academics, journals or governments.

If you have any other questions please feel free to call me or visit the TP web site I've been drafted to co-administer. http://terrapreta.bioenergylists.org/?q=node

It has been immensely gratifying to see all the major players join the mail list , Cornell folks, T. Beer of Kings Ford Charcoal (Clorox), Novozyne the M-Roots guys(fungus), chemical engineers, Dr. Danny Day of EPRIDA , Dr. Antal of U. of H., Virginia Tech folks and many others

Below is my current TP posting of News & Links which I promiscuously post to anyone who has an iron in this fire .

Cheers,
Erich


This technology represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.Terra Preta Soils a process for Carbon Negative Bio fuels, massive Carbon sequestration, 10X Lower CH4 & N2O soil GHG emissions, and 3X Fertility Too.

After many years of reviewing solutions to anthropogenic global warming (AGW) I believe this technology can manage Carbon for the greatest collective benefit at the lowest economic price, on vast scales.

Genesis Industries, licensee of Eprida technology, provides carbon-negative EPRIDA energy machines at the same cost as going direct to Eprida. Our technical support staff also provide information to obtain the best use of biochar produced by the machine. Recent research has shown that EPRIDA charcoal (biochar) increases plant productivity as it sequesters carbon in soil, thus reducing atmospheric carbon dioxide.
