En la presente obra se expone el efecto reductor de la cobertura vegetal y de raices de cultivos agricolas (maiz, frijol, calabacita y avena) sobre el proceso erosivo del suelo y agua en parcelas experimentales de temporal. En estas fue considerado el manejo convencional de suelo y la preparacion del terreno para la siembra bajo lluvia simulada. Los resultados obtenidos confirman una relacion exponencial negativa entre la cobertura vegetal y la perdida de suelo; observandose que el efecto de raices es menos eficiente para reducir el proceso erosivo. Los mayores registros de perdida de suelo promedio fueron obtenidos en el cultivo de maiz y los menores para avena. Todos los cultivos mostraron una relacion negativa del escurrimiento superficial con respecto al aumento de cobertura vegetal; a diferencia del desarrollo de las raices, del que solamente el maiz mostro un ligero efecto en reducir el escurrimiento superficial.

Environmental Soil Physics is a completely updated and modified edition of the Daniel Hillels previous, successful books, Introduction to Soil Physics and Fundamentals of Soil Physics. Hillel is a Pulitzer Prize-winning author, one of the true leaders in the field of environmental sciences. The new version includes a chapter and problems on computational techniques, addresses current environmental concerns and trends. Updates and expands the scope of Hillel's prior works, Fundamentals of Soil Physics (1980)and Applications of Soil Physics (1980) Explores the wide range of interactions among the phases in the soil and the dynamic interconnections of the soil with the subterranean and atmospheric domains Draws attention to historical and contemporary issues concerning the human management of soil and water resources Directs readers toward solution of practical problems in terrestrial ecology, field-scale hydrology, agronomy, and civil engineering Incorporates contributions by leading scientists in the areas of spatial variability, soil remediation, and the inclusion of land-surface processes in global climate models

Soil Biology brings together the microbiological, botanical, and zoological aspects of soil biology. Leading specialists provide critical reviews and assessments of their particular branches of soil biology, paying particular attention to functional aspects and biotic interrelationships whenever possible. This volume is organized into 17 chapters and begins with an overview of the soil system, emphasizing the system components including the mineral fraction, organic matter, soil moisture, and soil atmosphere. The next chapters focus on microorganisms present in the soil, along with their effects on plant roots. The book also discusses the soil algae, including how algae are affected by physical and chemical environments and their interrelations with other organisms. The remaining chapters look at other organisms that inhabit the soil, including Arthropoda, Collembola, and Mollusca, as well as the probable effects of inhibiting substances upon the biology of soil microorganisms. The final chapters explain the decomposition of organic matter in the soil and the effects of synthetic chemicals on soil microorganisms. This book is a valuable resource for soil biologists and research workers in fields such as botany, agriculture, zoology, and microbiology.

Comprises the proceedings of the International Conference on River Regime held at Wallingford, England, May 1988. Describes recent advances in river regime theory, including full discussion of the newly-developed analytical approach. This new approach employs a theoretical description of the dominant fluvial process rather than a purely empirical approach. Also gives an account of the increasing range of application of regime theory, from canals to sand bed streams and rivers, and, more recently, to gravel bed rivers (the latter application still being refined). Provides the latest laboratory data and field data, addresses both empirical and analytical approaches, and looks at channel form, meandering, and many additional factors in the growing science of river regime theory.
