In recent years, the growing realization that as much as 40–60% of the carbon in forest ecosystems is stored belowground has sparked a great deal of interest in exploring forest soil processes and their relation to carbon dynamics. Because of its slower turnover rates, soil organic carbon offers considerable potential to mitigate the increase in atmospheric carbon dioxide and alleviate the greenhouse effect. Through the publication of this book, the editors have done a remarkable job in bringing together the collective wisdom of 41 prominent soil scientists in analyzing the carbon sequestration potential of U.S. forest soils and the implications for policy decisions. This book is the third one in a series of books addressing the carbon sequestration potential of U.S. land use systems. The first two books examined the potential of crop and grazing lands and were published in 1999 and 2001, respectively.
