biocharBiochar, climate change and soil: A review to guide future researchCategory: Biochar - Documnet Type: Technical ReportBiochar is the charred by-product of biomass pyrolysis, the heating of plant-derived material in the absence of oxygen in order to capture combustible gases. The objective of this report was to review and evaluate published studies with regard to what evidence and arguments currently exist that assess the application of biochar to soil to a) sequester carbon and b) ...

US Senate Majority Leader Harry Reid Introduces "WECHAR" Bill to Develop Biochar TechnologyCategory: Policy Incentives - Documnet Type: OtherOn Thursday, September 24, 2009, US Senate Majority Leader Harry Reid of Nevada, and four cosponsors (Senators Max Baucus and John Tester of Montana, Senator Orrin Hatch of Utah, and Senator Tom Udall of New Mexico), introduced the "Water Efficiency via Carbon Harvesting and Restoration (WECHAR) Act of 2009." The bill establishes a loan guarantee program to develop biochar technology, in... More» Author: Harry Reid - submitted on Tue, 09/29/2009 - 21:34. Energy Balance and Emissions Associated with Biochar Sequestration and Pyrolysis Bioenergy ProductionCategory: Biochar - Documnet Type: Journal ArticleThe implications for greenhouse gas emissions of optimizing a slow pyrolysis-based bioenergy system for biochar and energy production rather than solely for energy production were assessed. Scenarios for feedstock production were examined using a life-cycle approach. We considered both purpose grown bioenergy crops (BEC) and the use of crop wastes (CW) as feedstocks....

Biochar in fertile clay soil: impact on carbon mineralization, microbial biomass and GHG emissionsCategory: Biochar - Documnet Type: OtherThe Aim of this project is the investigation of the short-term effects related to flash pyrolysis biochar amendments on soil fertility, nutrient dynamics, plant growth and green house gas (GHG) emissions. Further more it is planned to determine biochar characteristics in terms of environmental properties especially the biodegradability, the porosity and the cation exchange capacity (CEC)....

Characterization of Pyrolysis Char for Use as an Agricultural Soil AmendmentCategory: Biochar - Documnet Type: OtherThe Southeastern Coastal Plain in the United States is a major agricultural production area; however, soils are typically low in cation exchange capacity (CEC), nutrient content, and organic carbon content....

Use of charcoal and wood carbonization by-products in agriculture: learning with “Terra Preta de Índio”Category: Biochar - Documnet Type: OtherBrazil is the leading producer of charcoal in the world, being responsible for 38.5% of the world production. During the traditional process of carbonization, around 35% of the wood carbon is Author: Vinicius M. Benites, Etelvino H. Novotny, Wenceslau G. Teixeira, Beata E. Madari, Alexandre S.

The Italian Biochar Initiative (ITABI): Effects on soil fertility and on crops productionCategory: Biochar - Documnet Type: OtherThe mitigation of anthropogenic CO2 emissions is a key issue to reduce the unbalance in carbon cycle and the consequent global climate change. The increase of carbon sinks is considered to be one of the main short-to-mid term mitigation options and can be carried on trough different strategies.... More» Author: S. Baronti, G. Alberti, L.

S1884 Salazar Harvesting Energy Act of 2007Category: Policy Incentives - Documnet Type: OtherBioenergy production from agricultural and forestry biomass can boost U.S. energy independence, create additional income streams for agriculture and rural communities, and help combat global climate change by displacing fossil fuel use. Policies to promote bio-energy production from agricultural products must preserve the soil resources necessary to support adequate U.S.... More» Author: Sen.
