Opis

Soil degradation, a decline in soil quality due to anthropogenic perturbations, is a serious threat with negative impacts on agriculture and the environment. The assessment and monitoring of all forms of degradation is essential to the evaluation of negative trends and implementation of mitigating technologies. Soil Degradation in the United States: Extent, Severity, and Trends is an assessment of current trends and geographic hot spots. It not only describes the types of soil degradation, but also evaluates the processes and triggers that cause the damage.Written by world-renowned leaders in the field of soil science, the book is thematically divided into three sections: Section I addresses basic processes and discusses concepts and definitions, land use change, and global trends. Section II provides the data on soil degradation by various processes such as water and wind erosion, salt build-up, and soil contamination. Section III summarizes the magnitude and severity of degradation and addresses policy issues in relation to economic and environmental impact. Several appendices provide much needed information on past trends and future projections.This book is a state-of-the-art co

Soil Degradation in the United States: Extent, Severity, and Trends examines the magnitude and severity of soil degradation by different processes in the U.S., including water erosion, wind erosion, C depletion, soil compaction, salt build-up, and soil contamination. In addition, it addresses policy issues with regard to economic and environmental impact, land use change, and global trends. It covers past trends and future projections regarding soil degradation. The book provides a ready reference and data source for soil scientists and researchers, agronomists, environmentalists, land use planners, land managers, and policy makers.
