The International Biochar Initiative 2010 Conference

Conference LogoIBI held the 3rd International Biochar Conference: IBI 2010, in Rio de Janeiro, September 12 - 15, 2010. We hosted this conference in Brazil, together with our parters and colleagues at EMBRAPA--a leading light in studies of biochar and Terra Preta. The conference ran over the course of four days and included both oral and poster presentations, ample networking opportunities, side meetings, discussion groups, display booths, and a field trip opportunity to see the famous Terra Preta sites in the Amazon (September 16 - 18, 2010).


Session topics included: IBI logo

A History of Terra Preta de Indios in Brazil

The Terra Preta de Índios soils, found in the Amazon basin, differ markedly from adjacent soils with their higher fertility and greater carbon content. This high fertility of Terra Preta de Índios, and in particular the capacity of these soils to maintain high fertility despite their intensive and degradative use (resilience), is attributed to its high levels of soil organic matter of strong pyrogenic character. These special soils were formed by pre-Columbian Indigenous peoples, although it is unclear whether their formation was an intentional process for soil improvement, or a consequence of their agricultural and household activities. Such human activity in pre-Columbian past resulted in the accumulation of plant and animal residues as well as large amounts of ash and charcoal. The slow natural oxidation of these charred residues in the soil generated a recalcitrant (polycondensed aromatic structure) and reactive (rich in functionalities able to adsorb nutrients) material, giving rise to soils able to retain plant nutrients in an efficient form and thus reduce their leaching with the heavy rainfall of the Amazon environment.

All this knowledge allowed us to define a model to pursue the goal of improving soil fertility and promoting soil carbon sequestration. For this, biochar can be used, in its raw or improved form, as a soil amendment inspired by traditional indigenous pre-Columbian practices.

Reconciling food and energy production with of soil fertility and carbon sequestration.

It is important to highlight that the scientific approach is not to compete for energetic resources such as charcoal and sugarcane bagasse, but to optimize energy generation by using modern pyrolysis methods and recycling waste and by-products which often represent environmental liabilities. Biochar research and development was included in the 2008 United States Farm Bill and could be considered as official climate change mitigation and adaptation strategy, such as a voluntary C markets strategy, in the post-Kyoto climate agreement under the UNFCCC, representing an important advance, since it is the first proposal that does not penalise agricultural production.

As for Brazil, the agricultural use of biochar is included in Embrapa’s (Brazilian Agricultural Research Corporation) strategic research agenda because:

  1. Brazil is the world’s largest producer of plant charcoal (38.5% of the production).
  2. Renewable energy accounts for 50% of its total energetic matrix, contrasting with the world average of 14%;
  3. Alcohol from sugarcane, the main feedstock in Brazil’s renewable energy matrix, generates a fantastic quantity of pyrolyzable residues.  Additionally, emergent biofuels (biodiesel) industries potentially will produce tons of pyrolyzable residues;
  4. Our tradition in Terra Preta de Índios research has given us a distinct starting point regarding agricultural uses of biochar and modified charcoal as a soil amendment.
