Listeros,
National Geographic has posted an article on the amazing man-made
"super-dirt" or "terra Preta" ancient Amazonians used to create a
thriving civilization in the Amazon jungle in advance of their special
tonight on these ancient Amazonians on the NG Channel.
Scientists are now finding out that the dirt was a mixture of
charcoal, dirt, pottery, human excrement and other waste. They are now
trying to re-create the mixture which could help fight global warming
and feed the hungry. This "dark earth" is not of the natural yellowish
color of the regular soil in the jungle. The terra preta attracts
fungi and other microorganisms that make the soil fertile over long
periods. This soil is still working today to reduce acidity in the
jungle soil. This soil can reduce greenhouse gases by trapping carbon
that would ordinarily be released into the atmosphere and keep it
underground thus helping end slash and burn farming which does add to
global warming.
National Geographic has the story here with a video;
