Synopses & Reviews
The unique properties of black carbon-rich soils have only recently been recognized and international efforts have significantly increased to utilize this knowledge to improve agriculture and the environment in several ways. Biomass-derived black carbon, charcoal or biochar, as it is nowadays called, can be used as a soil amendment to improve nutrient retention and availability and therefore increase crop yields. Such a use of biochar is a significant advance over conventional organic matter management, as the biochar is more stable in soil and is better able to retain nutrients. In combination with sustainable biomass production, such a biochar sequestration can be carbon negative and therefore be used to actively remove carbon dioxide from the atmosphere, with obvious significance for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. This is all the more important at this juncture in the development of a biochar technology, as it requires an interdisciplinary approach involving engineering, environmental sciences, agricultural sciences, economics, and policy. The book provides a comprehensive overview of current knowledge of the science and technology of biochar.
Synopsis
Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.
