Scientists say terra preta can do much more than a box of Miracle-Gro. The process of making it pulls carbon out of the atmosphere, and can reduce global warming.
“The knowledge we can gain from studying the Amazonian dark earths, found throughout the Amazon River region, not only teaches us how to restore degraded soils, triple crop yields and support a wide array of crops in regions with agriculturally poor soils, but also can lead to technologies to sequester carbon in soil and prevent critical changes in world climate,” said Johannes Lehmann, a biogeochemist at Cornell University.
