This book summarises the main results of many contributions from researchers worldwide who have used the water infiltration process to characterize soil in the field. Determining soil hydrodynamic properties is essential to interpret and simulate the hydrological processes of economic and environmental interest. This book can be used as a guide to soil hydraulic characterization and in addition it gives a complete description of the treated techniques, including an outline of the most significant research results, with the main points that still needing development and improvement.

The practitioner or researcher often faces complex alternatives when selecting a method to characterize properties governing a soil process. After years of research and development, environmental and agricultural professionals now have an array of methods for characterizing soil processes. Well-established methods, however, may not be suitable for the specific conditions of a study since many soil characteristics are intrinsically variable. An objective, integrated approach for soil characterization is needed to more effectively quantify parameters. Soil-Water-Solute Process Characterization goes beyond technical guidance and addresses the complicating factors such as spatial and temporal variability of soil processes, scale issues, soil structure, and the trade-offs between methods. It focuses on advanced methods for the monitoring and modeling of mass transfer processes in soil. Expert contributors present limitations to well-known methods and alternatives, discussing their practical applications for characterization efforts, evaluating strengths and weaknesses, and focusing on a reduced set of selected techniques. Three in-depth sections cover everything from multidisciplinary approaches for assessing subsurface non-point source pollution to techniques for characterizing water and energy balances at the soil-plant-atmosphere interface, field methods for monitoring soil water status, and computer models for characterizing the effect of chemicals in soil. This single-source reference is transforming method selection and our understanding of the principles, advantages, and limitations of the available monitoring techniques. Written in a simple and straightforward manner, Soil-Water-Solute Process Characterization is a detailed cookbook and a useful, practical reference for students, practitioners, and researchers.

An abridged, student-oriented edition of Hillel's earlier published Environmental Soil Physics, Introduction to Environmental Soil Physics is a more succinct elucidation of the physical principles and processes governing the behavior of soil and the vital role it plays in both natural and managed ecosystems. The textbook is self-contained and self-explanatory, with numerous illustrations and sample problems. Based on sound fundamental theory, the textbook leads to a practical consideration of soil as a living system in nature and illustrates the influences of human activity upon soil structure and function. Students, as well as other readers, will better understand the importance of soils and the pivotal possition they occupy with respect to careful and knowledgeable conservation. Written in an engaging and clear style, posing and resolving issues relevant to the terrestrial environment Explores the gamut of the interactions among the phases in the soil and the dynamic interconnection of the soil with the subterranean and atmospheric domains Reveals the salient ideas, approaches, and methods of environmental soil physics Includes numerous illustrative exercises, which are explicitly solved Designed to serve for classroom and laboratory instruction, for self-study, and for reference Oriented toward practical problems in ecology, field-scale hydrology, agronomy, and civil engineering Differs from earlier texts in its wider scope and holistic environmental conception

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.

This book contains the proceedings of the first workshop held at Monte Verità near Ascona, Switzerland on September 24-29, 1989. The workshop was designed to survey the current understanding of water and solute transport through unsaturated soils under field conditions, and to foster research by discussing some unresolved key issues relative to transport modeling and experimentation in four "Think Tank" groups. The first part of this book consists of the reports prepared by the Think Tank groups, who discussed the following topics: modeling approaches, effective large scale properties, evaluation of filed properties, and the role preferential flow. The second part contains a selection of reviewed original contributions presented at the workshop, with topics ranging from the presentation of results from large scale experiments, to improved or new modeling approaches, and to legal or policy aspects. This book is intended for researchers in soil science, hydrology, and environmental engineering who have an interest in transport and reaction processes in the unsaturated zone. It will provide them with a representative sample of current research activities, and with a group discussion of future research directions in four important areas of water and solute transport.

Animals including humans are highly dependent on plants to provide many different nutrients including iron in a useable form. Additionally, plants are used to support the growth of animals and obtaining high crop yields via optimal plant growth is an economic necessity. Thus, it is crucial to understand the role of iron in plant nutrition. This book provides comprehensive reviews on topics of plant-iron nutrition that are being addressed by different laboratories around the world. As one can see, the area of plant-iron nutrition is highly interdisciplinary, involving scientists of various fields of knowledge. Plant biologists are needed to characterize iron translocation throughout the plant following root iron uptake and to examine the regulation of iron-stimulated activities that influence crop yield and quality. Plant geneticists are contributing to the area of plant-iron nutrition by developing model systems to aid our understanding of the complex activities of the individual plant. Soil chemists are examining the interactions between iron and various minerals and organic matter soil components in the root zone. Microbiologists are providing a crucial perspective on how the interactions between the plant and soil microorganisms are important in plant iron nutrition. Additionally, the cycling of iron in the terrestrial environment is being examined by ecologists and related scientists. While it may be ideal to systematically examine iron nutrition in a single plant species, research is influenced by local or regional requirements.
