Charcoal and Soil
•Black carbon, charcoal, a component of soil
–more durable than other organic forms
–possibly forest and grass fires produced
•Amazonian agriculture
–some areas of rich black soil
–possibly man made centuries ago
–charcoal  from variation of slash and burn?
•Huge potential for soil and sink
I’m personally excited about some surfacing ideas on the production and use of charcoal as a soil amendment and fertilizer.
Some durable long lasting carbon is found in soils. Some of this is simply charcoal, presumably from forest and grass fires and has been there for centuries.
Carbon rich black soils have been found in the Amazon.  This soil was possibly man made.  Some scientists suggest it was deliberately produced by a variation of slash and burn agriculture.  These soils are said to remain highly productive long after their formation.
