图书简介
Using data from the long-term Calhoun Forest Experiment, this book explores a legacy of soil change in a region of ecological, agricultural and forestry significance. The resulting synthesis provides lessons for land management throughout the world and illustrates the need for a global network of similar soil-ecosystem study sites.
