Download or read book Saline and Sodic Soils written by E. Bresler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In keeping with the spirit of an Advanced Series in the Agricultural Sciences, we have attempted to address herein most of the current research areas being used to characterize, describe and manage salt-affected soils. Because of a certain amount of personal bias inherent in our individual viewpoints and backgrounds, some areas have been accorded more emphasis than others. It has been our goal, however, to provide either detail about, or at least a recent reference to, each major area of current soil salinity research. This information, coupled with what we hope to be a rather logical progression from descriptive material on equilibrium or near-equilibrium soil chemistry, through transport processes, to eventual management practices including some elementary economic decisions, should enable the reader to bridge the gap from introductory soil chemistry or soil physics texts to the basic literature of this area. The text will be perceived by the astute reader as somewhat uneven in its treatment of respective sections. We feel that this is to a certain extent appropriate, for it thus portrays the unevenness of progress to date in the corresponding areas of research. The management of saline and sodic soils remains largely an empirical semi-science or even art, whereas transport phenomena are normally dealt with in a much more theoretical (and also a much more highly mathematical) vein. Equilibrium soil chemistry has historically occupied an intermediate position with respect to its mix of empiricism and theoretical rigor.
Download or read book Development of Pedotransfer Functions in Soil Hydrology written by Yakov Pachepsky and published by Elsevier. This book was released on 2004-12-30 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental and agricultural modeling and assessment have a multitude of uses for soil parameters governing retention and transport of water and chemicals in soils. These parameters are notorious for the difficulties and high labor costs involved in measuring them. Good estimates instead of direct measurements may be accurate enough for many applications. Pedotransfer functions provide such estimates by utilizing available soil survey information to translate data we have into data we need. This book is the first book on the topic. It provides the unique compendium of pedotransfer functions, summarizes the vast international experience in this field, and shows how the value of soil data can be increased by using them in pedotransfer functions to predict soil hydrologic and related properties. The book is a rich source of information crucial for environmental research and applications.
Download or read book Soil Subsurface Change written by Bruno Yaron and published by Springer Science & Business Media. This book was released on 2012-02-18 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book combines soil science, earth science, and environmental geochemistry, providing comprehensive background information for specialists interested in chemical-induced changes in the soil-subsurface system. Readers are introduced to the chemistry of contaminants that often disturb the natural soil-subsurface equilibrium as a result of human activity. While the soil-subsurface system has in many cases been affected by human impact, the effects of chemical contaminants on the actual matrix and properties have been largely neglected. The major focus of the book is on changes to the soil-subsurface matrix and properties caused by chemical pollution. By integrating results available in the literature, we observe that chemical pollutants may lead to the irreversible formation of a new soil-subsurface regime characterized by a matrix and properties different than those of the natural regime. In contrast to the geological time scales dictating natural changes to the matrix and properties of the soil-subsurface system, the time scale associated with chemical pollutant-induced changes is far shorter and extends over a “human lifetime scale.” The numerous examples presented in the book confirm that chemical contamination should be considered as an additional factor in the formation of a contemporary soil-subsurface regime that is different than that of the pristine system.
Download or read book Fundamentals of Soil Physics written by Daniel Hillel and published by Academic Press. This book was released on 2013-10-22 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is not, in any case, in total defiance of the Wise Old Man's admonition, for it is not an entirely new book. Rather, it is an outgrowth of a previous treatise, written a decade ago, entitled "Soil and Water: Physical Principles and Processes." Though that book was well enough received at the time, the passage of the years has inevitably made it necessary to either revise and update the same book, or to supplant it with a fresh approach in the form of a new book which might incorporate still-pertient aspects of its predecessor without necessarily being limited to the older book's format or point of view.

Download or read book Salinity Effects on Soil water Diffusivity written by Luiz Antonio Lima and published by . This book was released on 1986 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt effects on water movement in usaturated Yolo loam soil are explored by comparing soil-water diffusivity values determined by Bruce and Klute's method in soil columns treated with SAR values 0,5 and 15 and wetted with water containing 15, 5, 2 and 0 me/l. Sorptivity values for these conditions are also compared. Total soil solution concentration estimated by electrical conductivity measurements and NA and CA concentrations measured by flame photometry are discused. Salt effects on soil-water diffusivity were more pronounced at larger values of water content. Movement of water in Ca-saturated samples was significantly affected only when the soil solution concentration was smaller than approximately 2 me/l. Soil samples treated with SAR 5 presented reductions in soil-water diffusivity when the solution concentration was equal to or smaller than approximately 3,5 me/l and the water content larger than 0,35 cm3/cm3. The soil-water diffusivity was also affected when the solution concentration was equal to or smaller than approximately 2 me/l and the water content larger then 0,30 cm3/cm3. Soil-water diffusivity of samples treated with SAR 15 was affected basically at all values of water content when the soil solution concentration was equal to or smaller than approximately 3,5 me/l. When such concentration was a large as 5 me/l, reductions in soil-water diffusivity were apparent only for water contents larger than 0,25 cm3/cm3. Chemical analyses of soil solution after infiltration revelated that most soluble salts in the soil column were carried near the wetting front. Significant displacement of Na by Ca occurred in soils treated with SAR 5 and 15. Although Bruce and Klute's method does not apply for chemically unstable and swelling soils, the slope of the plot of distance to the wetting front versus square root of time fitted the Boltzman variable for the water content of wetting front satisfactorily. This fact suggests good reliabillity of reported soil-water diffusivity values.

Available in PDF, EPUB and Kindle. Book excerpt: Foundations on Expansive Soils provides the practicing engineer with a summary of the state-of-the-art of expansive soils and practical solutions based on the author's experience. The book is organized into two parts. Part I deals with theory and practice, and summarizes some of the theoretical physical properties of expansive soils. It also discusses various techniques employed to found structures on expansive soils such as drilled pier foundation, mat foundation, moisture control, soil replacement, and chemical stabilization. Topics covered include the origin, mineralogical composition, and the basic structure of expansive soils; the migration of water, swelling potential, and swelling pressure; site investigations and laboratory testing; moisture control; and soil stabilization. Part II presents case studies on the following: distress caused by pier uplift; distress caused by the improper design and construction of a drilled pier foundation system; distress caused by heaving of footing pad and floor slab; distress caused by heaving of continuous footings; and distress caused by a rise of ground water.
