This textbook is concerned with the physical properties of soils and their relation to other soil properties. It discusses the transport of water, heat, solutes, and oxygen in soil and the impact of soil water on the growth and development of plants. For the student, the purposes of this book are to develop an understanding and appreciation for the physical properties of soils and their impact on agriculture, natural resources, and the environment; to explore how soil, plant, and engineering sciences use the knowledge of soil physical behaviour; and to develop mathematical and quantitative skills needed to solve applied problems in soil science. Each chapter includes definitions of essential terms and concepts with numerous examples and problems, which present opportunities for students to review and apply their knowledge to real-world cases.
H. Dan Scott is a university professor of soil physics in the Department of Crops, Soil, and Environmental Sciences at the University of Arkansas, Fayetteville. Dr. Scott s research interests cover most aspects of soil-water crop relationships. His studies include geographical information systems in agriculture and natural resources, the effects of tillage and crop management practices on the spatial and temporal variability of soil physical properties, and the modeling of pesticide movement to surface and ground waters.
