Soil is one of the most important resources in the world, and securing healthy and safe soil is vital to meeting the challenging of growing food demand for an increasing population. This book offers the reader the latest research in methods for quality and risk assessment, as well as pointing to new trends and directions. In the first part, current approaches to quality assessment are introduced. Topics discussed include the application of topographical factor modelling, remediation for heavy metals contamination, spectroscopic approaches to assessing stability of organic matter, and the effects of crop rotation and nitrogen fertilization on soil organic matter. In the second part, contributors examine the risk assessment of soil contamination. Topics considered include treatment methods for radioactive wastes, phytoremediation of contaminated soils in mining areas and around the River Yamuna in India, geochemical speciation, and the effect of heavy metal pollution on microbial abundance and diversity. The books contemporary, global perspectives ensure it is a vital resource for students and researchers with interests in soil science and environmental hazard management.
