Hi Erich,

"AMAZON SOIL TECHNIQUE REDUCES GREENHOUSE GASES"
Australian scientists are adapting a soil fertility technique used in the Amazon to reduce greenhouse gas emissions.
For thousands of years, Amazonian Indians burned their waste organic matter in low-intensity fires and added the charred material to their land.
The method improved fertility on intensively-managed soils, but is now being considered as a way of trapping excess carbon.
Researcher Lucas Van Zweiten says carbon can be stored for thousands of years.
"In composting, the majority of carbon in the composting process is lost naturally to microbial degradation to carbon dioxide," he said.
"In pyrolisys up to 50 per cent of carbon is maintained as char which can last for several thousand years in the soil."
