Can Amazonian Terra Preta Transform Soil?

Can Amazonian Terra Preta Transform Soil?

Cornell scientists have high hopes for the potentials of biochar, one of the primary ingredients in the rich terra preta (perhaps the Amazon's true El Dorado). They posit “up to 12 percent of the carbon emissions produced by human activity could be offset annually if slash-and-burn were replaced by slash-and-char.” Lessons from terra preta are further guiding scientists to solutions in reducing agricultural runoff and input costs while promoting long-term fertility.
