Soils are the porous skin of the Earth with variable and complex structures composed of solid, liquid and gaseous phases. This textbook (based on the 4th, German language edition) introduces the reader gently but comprehensively to soil physical processes. The authors discuss both the origin and dynamics of soil physical properties and functions -- including volume-mass relations of the solid, water and gas phases, grain and pore size distributions, permeability and storage capacity for water, gases and heat -- and finally soil deformation and strength in relation to mechanical and hydraulic stresses resulting in structural changes through compaction, kneading, slaking and soil crusting.
Essential Soil Physics by K. H. Hartge,Rainer Horn Pdf
Soils are the porous skin of the Earth with variable and complex structures composed of solid, liquid and gaseous phases. Being in close contact with the atmosphere, biosphere hydrosphere, and lithosphere, soils fulfill numerous functions as a filter, buffer, habitat for organisms and resource for raw materials and food rendering them as the basis for life on our Planet. Soils are subject to continuous transformations and their dynamic nature is important for the interaction of biological, biogeochemical and physical processes. At the same time soils are vulnerable and affected by human activity and often subject to degradation. This textbook (based on the 4th, German language edition) introduces the reader gently but comprehensively to soil physical processes. The authors discuss both the origin and dynamics of soil physical properties and functions - volume-mass relations of the solid, water and gas phases, grain and pore size distributions, permeability and storage capacity for water, gases and heat - and finally soil deformation and strength in relation to mechanical and hydraulic stresses resulting in structural changes through compaction, kneading, slaking and soil crusting. Unlike other soil physics textbooks, soil mechanical properties are herein described in great detail, because otherwise it is impossible to understand and adequately quantify soil stability and the effects of soil deformation on soil physical functions. The book treats the physics of water, gas and heat movement in soils and interactions with the solid phase at various scales and other factors in detail -- because these are considered the ultimate basis of any model of soil behavior. Threats to soils worldwide ultimately endanger food security for a growing world population. Because of this, the effects of soil use and degradation on transport processes, soil stability and pore functions are discussed, and options for soil protection, conservation, and amelioration are addressed. The authors close a gap between general soil science texts and very specialized treatments of foundation engineering by integrating the concepts of soil mechanics to achieve a comprehensive description of soil physical behavior. Traditional soil physics topics, such as soil - water - plant relations, soil hydrology and gas, heat and field water cycles are complemented by soil rheology, physicochemical and amelioration sciences. Well-known and recent advances in analytical approaches and methods are well explained to be of use to persons interested in improving plant growth and optimizing crop yield. This book is valuable for researchers, upper-level undergraduate students, and graduate students of agronomy, soil science, horticulture, geo-sciences, environmental science, landscape architects and everybody interested in understanding the intricate physical processes which control and modify soil functions. Problems are provided at the end of each chapter to enable readers to develop soil physics related problem solving skills.

Principles of Soil Physics by Rattan Lal,Manoj K. Shukla Pdf
Principles of Soil Physics examines the impact of the physical, mechanical, and hydrological properties and processes of soil on agricultural production, the environment, and sustainable use of natural resources. The text incorporates valuable assessment methods, graphs, problem sets, and tables from recent studies performed around the globe and offers an abundance of tables, photographs, and easy-to-follow equations in every chapter. The book discusses the consequences of soil degradation, such as erosion, inhibited root development, and poor aeration. It begins by defining soil physics, soil mechanics, textural properties, and packing arrangements . The text continues to discuss the theoretical and practical aspects of soil structure and explain the significance and measurement of bulk density, porosity, and compaction. The authors proceed to clarify soil hydrology topics including hydrologic cycle, water movement, infiltration, modeling, soil evaporation, and solute transport processes. They address the impact of soil temperature on crop growth, soil aeration, and the processes that lead to the emission of greenhouse gases. The final chapters examine the physical properties of gravelly soils and water movement in frozen, saline, and water-repellant soils. Reader-friendly and up-to-date, Principles of Soil Physics provides unparalleled coverage of issues related to soil physics, structure, hydrology, aeration, temperature, and analysis and presents practical techniques for maintaining soil quality to ultimately preserve its sustainability.
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.

Soil Physics: Selected Topics covers the results in the research field of soil physics, soil mechanics, and the behavior of real soils. This book is divided into six chapters and begins with an introduction to the study of the physical characteristics of soil and the complexity of superstructure of soil mechanics. The next chapter deals with the distribution of coarse grains according to their volume and the distribution of pore sizes in fine-grained materials. This chapter also describes the properties of granular mixtures and the compatibility of transition soils. The discussion then shifts to investigation of soil strength, particularly the strength of sand and transition soils, the tensile and shear strengths of cohesive soils, and brittle failure of soils. The remaining chapters consider the classification of soil phase movement phenomena. This book is intended primarily for practicing civil engineers.
