Book Description
Vertisols, one of the eleven established soil orders, are clay soils with unusual and interesting properties. They cover more than 350 million hectares of land in the world and in tropical Africa alone there are over 100 million hectares. Because of their very small particle size and high surface area, these soils have higher physical and chemical reactivity than other soils. Their interaction with agrochemicals/industrial wastes, has been, increasingly, the subject of research especially in the last two decades. Vertisols create special problems when used for engineering purposes. This book is intended to provide comprehensive and state-of-the-art information about Vertisols worldwide. Special attention is given to the use and management of soils such as fertilizer use, crop selection, soil tillage, water restriction on land including irrigation, and soil erosion. A special chapter has been added to deal with geotechnical engineering of Vertisols. Vertisols have great potential for agricultural production but many, especially in the developing world, are underutilized due to a lack of understanding regarding their behaviour and management. This book is written by leading scientists worldwide. It is expected that this monograph will be of great use to soil scientists and agronomists, graduate and senior graduate students. Improvement of their management may solve the current food deficiency in the world.

Book Description
The book includes selected papers from those presented at the International Working Meeting on Soil Micromorphology in San Antonio, Texas, July 1988. Each section of the book is introduced with an invited plenary paper followed by selected contributed manuscripts. The volume is intended to give the reader insight into the more recent research work involving soil micromorphology and an evaluation of the present day state of the science. New applications of micromorphology to both lunar pedology and archeology are presented. Recently developed methods for staining of microorganisms and thin section fluorescence microscopy are presented. The volume presents a summary of the research findings of the major practitioners of soil morphology and will give the reader insight as to the present state of the discipline. New methods and techniques will be made available to the reader.The book is intended for students, practicing micromorphologists, soil scientists, geologists, and geomorphologists.

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

Book Description
This book is based on a workshop held in Zimbabwe, May 1999, organized by the Department of Research and Specialist Services (Zimbabwe) and the International Board for Soil Research and Management (IBSRAM). Reviewing the current state of knowledge on and the practical aspects of the management of Vertisols in Africa, this book also includes comparative chapters covering other parts of the world, such as India, Australia and Texas (USA).

Book Description
Three themes run through this book, the first is the history of the Nile; the second is the degree to which the present Sudanese landscape reflects the operation of former geological processes; the third is the interaction between man and environment, not always to the benefit of either. A land between two Niles is an interdisciplinary account of the origins and characteristics of the alluvial plains of the lower Blue and White Nile. The contributors have focussed their attention upon this region for several reasons. Although the Gezira plain itself only occupies about one percent of the total area of the Sudan, the high quality long-staple cotton grown there provides nearly two-thirds of the country’s total export revenue.
