Interpretation of Micromorphological Features of Soils and Regoliths
Author: Georges StoopsPublisher: Elsevier
ISBN: 0444635424
Category : Science
Languages : en
Pages : 1002
Book Description
Interpretation of Micromorphological Features of Soils and Regoliths, Second Edition, provides researchers and students with a tool for interpreting features observed in soil thin sections and through submicroscopic studies. After an introduction and general overview, micromorphological aspects of regoliths (e.g., saprolites, transported materials) are highlighted, followed by a systematic and coherent discussion of the micromorphological expression of various pedogenic processes. The book is written by an international team of experts in the field, using a uniform set of concepts and terminology, making it a valuable interdisciplinary reference work. The following topics are treated: freeze-thaw features, redoximorphic features, calcareous and gypsiferous formations, textural features, spodic and oxic horizons, volcanic materials, organic matter, surface horizons, laterites, surface crusts, salt minerals, biogenic and pedogenic siliceous materials, other authigenic silicates, phosphates, sulphidic and sulphuric materials, and features related to faunal activity. The last chapters address anthropogenic features,archaeological materials and palaeosoils. - Updates the first exhaustive publication on interpretation of micromorphological features, with some new chapters and with a larger number of additional references - Covers related topics, making micromorphology more attractive and accessible for geomorphologists, archaeologists and quaternary geologists Includes thematic treatment of a range of soil micromorphology fields and broadens its applications - Features input from a multi-disciplinary team, ensuring thorough coverage of topics related to soil science, archaeology and geomorphology
Soil Crust Formation

Author: A.J. Ringrose-VoasePublisher: Elsevier
ISBN: 0080869904
Category : Science
Languages : en
Pages : 901
Book Description
The papers in this volume cover micromorphological studies of a wide variety of topics, at various scales from ultramicro- to mesoscopic. Topics included are:soil management; soil structure; surface crusts; hardpans and cemented layers; soil biota; soil genesis; hydromorphic soils; paleosols; archeology; and general pedology. The range of papers reflects the growing use of soil micromorphology in understanding soil problems in land-use and the increasing use of quantitative techniques, together with more traditional applications in pedology. The book is well illustrated with micrographs and contains both author and keyword indices.

Book Description
The world population in 1930 was 2 billion. It reached 3 billion in 1960, stands at 4. 6 billion today, and is expected to reach 6 billion by the end of the century. The food and fiber needs of such a rapidly increasing population are enormous. One of the most basic resources, perhaps the most basic of all, for meeting these needs is the soil. There is an urgent need to improve and protect this resource on which the future of mankind directly depends. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food production in the future is unimpaired. This is indeed a mammoth task; a 1977 United Nations survey reported that almost one-fifth of the world's cropland is now being steadily degraded. This volume is the first of a new series entitled Advances in Soil Science. The diversity of soil makes it necessary for research to be conducted in many locations. There are basic principles, however, that are universal. This new series will present clear and concise reviews in all areas of soil science for everyone interested in this basic resource and man's influence on it. The purpose of the series is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifYing additional research needs.

Biological Soil Crusts: An Organizing Principle in Drylands
Author: Bettina WeberPublisher: Springer
ISBN: 3319302140
Category : Nature
Languages : en
Pages : 540
Book Description
This volume summarizes our current understanding of biological soil crusts (biocrusts), which are omnipresent in dryland regions. Since they cover the soil surface, they influence, or even control, all surface exchange processes. Being one of the oldest terrestrial communities, biocrusts comprise a high diversity of cyanobacteria, algae, lichens and bryophytes together with uncounted bacteria, and fungi. The authors show that biocrusts are an integral part of dryland ecosystems, stabilizing soils, influencing plant germination and growth, and playing a key role in carbon, nitrogen and water cycling. Initial attempts have been made to use biocrusts as models in ecological theory. On the other hand, biocrusts are endangered by local disruptions and global change, highlighting the need for enhanced recovery methods. This book offers a comprehensive overview of the fascinating field of biocrust research, making it indispensable not only for scientists in this area, but also for land managers, policy makers, and anyone interested in the environment.
