Digital Terrain Analysis in Soil Science and Geology, Second Edition, synthesizes the knowledge on methods and applications of digital terrain analysis and geomorphometry in the context of multi-scale problems in soil science and geology. Divided into three parts, the book first examines main concepts, principles, and methods of digital terrain modeling. It then looks at methods for analysis, modeling, and mapping of spatial distribution of soil properties using digital terrain analysis, before finally considering techniques for recognition, analysis, and interpretation of topographically manifested geological features. Digital Terrain Analysis in Soil Science and Geology, Second Edition, is an updated and revised edition, providing both a theoretical and methodological basis for understanding and applying geographical modeling techniques. Presents an integrated and unified view of digital terrain analysis in both soil science and geology Features research on new advances in the field, including DEM analytical approximation, analytical calculation of local morphometric variables, morphometric globes, and two-dimensional generalized spectral analytical methods Includes a rigorous description of the mathematical principles of digital terrain analysis Provides both a theoretical and methodological basis for understanding and applying geographical modeling

This book presents the state-of-the-art after fifteen years of exponentially growing applications of fractal geometry in soil science. It demonstrates the wide-ranging applicability of fractal models in soil science and indicates new opportunities to integrate processes in soils within or across scales using fractals. Contributed by some of the pioneers in the field, chapters represent a broad spectrum of applications from geochemistry to microbiology and from scales of micrometers to the landscape, and serve as an introduction to the subject. Topics include fractal aspects of soil structure, porosity and texture, scaling in preferential and hydraulic conductivity, anoxic volumes and adsorption in fractal models of soil, characterization of the pore surface irregularity, fractal properties of soil organic matter, fractal concepts in studies of soil fauna and mycelium in soils, and fractal analysis of spatial and temporal variability in soil properties and crop yields. A wide spectrum of methods for identifying and measuring fractal properties is introduced and critically discussed. Although the book focussed on solving problems in soil science, the applications and the fractal approach used share much in common with many other fields within and outside of the earth sciences. A unique bibliography on fractals in soils science is included.

Thoroughly updated and revised, this second edition of the bestselling Soil Sampling and Methods of Analysis presents several new chapters in the areas of biological and physical analysis and soil sampling. Reflecting the burgeoning interest in soil ecology, new contributions describe the growing number and assortment of new microbiological techniques, describe in-depth methods, and demonstrate new tools that characterize the dynamics and chemistry of soil organic matter and soil testing for plant nutrients. A completely new section devoted to soil water reviews up-to-date field- and laboratory-based methods for saturated and unsaturated soil hydraulic properties. Retaining the easy-to-follow, “cookbook” style of the original, this second edition provides a compilation of soil analytical techniques that are fast, straightforward, and relatively easy-to-use. Heavily referenced, peer-reviewed contributions from approximately 150 specialists make this a practical manual and resource handbook that describes a wide array of methods, both conventional and cutting-edge, for analyzing the chemical, biological, biochemical, and physical properties of many different soil types. Including several “primer” chapters that cover the overall principles and concepts behind the latest techniques, the book presents sufficient detail on the materials and procedures to characterize the potential and limitation of each method. It covers recent improvements in methodology, outlines current methods, and characterizes the best methods available for selecting the appropriate analysis technique. Promoting the research and practical application of findings in soil science, Soil Sampling and Methods of Analysis, Second Edition continues to be the most current, detailed, comprehensive tool for researchers and practitioners working with soil.

Soil Magnetism: Applications in Pedology, Environmental Science and Agriculture provides a systematic, comparative, and detailed overview of the magnetic characterization of the major soil units and the observed general relationships, possibilities, and perspectives in application of rock magnetic methods in soil science, agriculture, and beyond. Part I covers detailed magnetic and geochemical characterization of major soil types according to the FAO classification system, with Part II covering the mapping of topsoil magnetic signatures on the basis of soil magnetic characteristics. The book concludes with practical examples on the application of magnetic methods in environmental science, agriculture, soil pollution, and paleoclimate. Provides an overview of the major findings of uncontaminated soil profiles and proposes a system of magnetic characteristics Elucidates the relationship between geochemical and magnetic characteristics of different soil types, providing a basis for wider recognition and application of soil magnetism in classical pedagogical characterization of soils Covers the peculiarities of the main taxonomic soil groups in terms of magnetic mineralogy and depth variations in concentration, grain size, and phase composition of iron oxides

Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.

This book presents practical information about hemispherical photography from the perspectives of field data acquisition, image processing and information retrieval methods. This book is organized into three sections. The first section describes what is hemispherical photography and what are the fundamental elements of forest structure and light interactions within the forest canopy. The second section provides practical information about the equipment, procedures and tools for procuring, processing and analyzing hemispherical photographs. Armed with this information, the third section describes several applications of hemispherical photographs to forestry and natural resource assessment. The book concludes with a discussion about modelling tools and future directions of this rapidly growing field. There is currently no information source on the market that has this comprehensive range of topics combined in a single book. The book will appeal to academics, graduate students, natural resource professionals and researchers alike.

The soil which is found in large cities offer distinctive challenges to the landscape architect or horticulturist responsible for maintaining these urban plantings. Often compacted, contaminated, or otherwise unsuitable for use in major landscape projects, these soils require practical methods which can insure a successful outcome of a landscape project. This applications-oriented, introductory reference addresses numerous topics in the field of urban soil science.
