Quote:
There is even a potentially revolutionary technique waiting to be developed that could greatly accelerate carbon storage in soils.
The technique is called "Terra Preta," Portuguese for "black earth." It is not new. It was invented by an ancient agricultural civilization in the Amazon that made charcoal and buried it the soil. The charcoal absorbs and holds nutrients from manure and supports beneficial microbes. Some of these fertile soils are more than 1000 years old. You can read more about Terra Preta in 1491: New Revelations of the Americas Before Columbus, by Charles C. Mann.
