Written in a clear, accessible style, this book presents the fundamental aspects of soil science for landscape architects and professionals in related fields. Emphasis is placed on those topics of particular interest to this audience, among them erosion, irrigation, fertility and nutrients, diagnosis of plant disorders, engineering aspects, and the use of soil surveys. The book should also find some course use in departments of landscape architecture and agronomy. Serious gardeners might find it of interest as well.

Written in a clear, accessible style, this book covers the fundamental aspects of soil science with an emphasis on topics useful to landscape architects and professionals in related fields. The book begins with a discussion of soil surveys developed in different countries, followed by a concise description of soil components and how the interactions between air, water, and nutrients affect plant growth. It examines methods for controlling erosion, particularly in light of modern irrigation techniques. It describes the chemistry of plant growth, devotes four chapters to macro- and micro-nutrients, and features a detailed discussion of ways to diagnose and correct plant disorders. It also looks at the engineering aspects of soils and includes a detailed list of references for further information. Written by an experienced teacher with an extensive background in landscape architecture, this volume will be an invaluable source for students and researchers in architecture, horticulture, and urban planning.

The research papers in this text were presented as part of the Fourth International Conference on the Biogeochemistry of Trace Elements. The purpose of the conference was to present late-20th century knowledge of the sources, pathways, behaviour and effects of trace elements in soils, waters, plants and animals. The book is intended for a variety of readers, including public health and environmental professionals, industrial hygienists, consultants, waste management professionals, and academics. It may also prove valuable to scientists conducting research on coal and coal combustion byproducts.

The accumulation of large amounts of ash from fossil fuel combustion for electric power plant generation is becoming a major environmental concern in the United States. Furthermore, stringent environmental regulations mandated by the Environmental Protection Agency through the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, as well as state and local environmental regulations may result in even more ash production with subsequent contact with the environment. The concentrations of trace elements in coal residues are extremely variable and depend on the composition of the original coal, conditions during combustion, the efficiency of emission control devices, storage and handling ofbyproducts, and climate. The research papers in this book were presented as a part of the Sixth International Conference on the Biogeochemistry of Trace Elements held at the University of Guelph, Ontario, Canada, from July 29-August 2, 2001. The purpose of this corit'erence was to present current knowledge on the source, pathways, behavior and effects of trace elements in soils, waters, plants and animals. In addition, the book also includes invited research papers from scientists who have done significant research in the area of coal and coal combustion byproducts. All the research papers presented herein have been subjected to peer review.

Trace Elements in Coal and Coal Combustion Residues focuses on trace metal chemistry of coal and coal combustion residues. Special emphasis is placed on management of coal combustion residues in electric power plants and the influence of coal and associated residues on soils, plants, water, and animals. Topics covered include a brief summary of research sponsored by Electric Power Research Institute, environmental pollution from coal combustion plants in low-rainfall regions, accumulation of trace elements in freshwater mussels near a power plant, testing to evaluate fossil fuel wastes by chemicals and isotopes, transport of metals from coal piles and ash impoundments, leachability and toxicity of metals in fly ash, and plant absorption of chemicals from ash. The book will be a useful reference for environmental and reclamation consultants, environmental engineers, toxicologists, environmental regulatory personnel, officials with electric power utilities and water treatment plants, and soil scientists.
