As the world’s population continues to expand, maintaining and indeed increasing agricultural productivity is more important than ever, though it is also more difficult than ever in the face of changing weather patterns that in some cases are leading to aridity and desertification. The absence of scientific soil inventories, especially in arid areas, leads to mistaken decisions about soil use that, in the end, reduce a region’s capacity to feed its population, or to guarantee a clean water supply. Greater efficiency in soil use is possible when these resources are properly classified using international standards. Focusing on arid regions, this volume details soil classification from many countries. It is only once this information is properly assimilated by policymakers it becomes a foundation for informed decisions in land use planning for rational and sustainable uses.

Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: *practical guidelines on the soil physical measurements across a range of soils, climates and land uses; *straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and *guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.

As we enter the last decades of the twentieth century, many persistent and perplexing problems continue to afflict humankind. Thus it is appropriate to address, in a new group of books, two of the monumental issues that haunt people throughout the world. Soils and the Environment by Professor Gerald W. Olson is the first book in this new publish ing program on Environment, Energy, and Society. The purpose of all these books will be to explore the many interrelated facets of these topics and to provide guidance for deal ing with problems and offering ideas for their solutions. Environment and energy are twin problems that occupy what many believe to be opposite sides of a two-headed coin. They are often viewed as being antithetical and incompatible. The various books in this program will try to place in perspective the options that are available to those who design policy and plan and manage societal matters. Typical of books being developed currently are ones on coal resources, environmental geoscience, environmental pollution, land-use planning, nuclear energy, mineral resources, and water resources. However, because soils are at the very heart of civilization and provide the building block for human sustenance, it is fitting to inaugurate this series with Dr. Olson's timely analysis of soils. Unfortu nately, these most vital resources seen. to have low priority in many farming enterprises, urbanization projects, deforestation schemes, and mining and developmental terrain changes.

Profiles in the History of the U.S. Soil Survey offers a broad-ranging collection of essays chronicling the development of the U.S. Soil Survey and its influence on the history of soil survey as a scientific discipline that focuses on mapping, analysis, and description of soils. Appraises the influences of key individuals and institutions on the establishment of federal support for and coordination of U.S. soil surveys. Provides an account of life in the field, detailing experience shared by many soil scientists and survey processionals. Reviews the opening of careers in soil survey to women and African-Americans. Relates aspects of the utility of the soil survey to other federal services, to other fields of research, and to land-use planning. Discusses the future of the U.S. Soil Survey and the new directions both the survey and its uses will take. Soil scientists and other soil survey professionals will find this collection valuable both for the new research it provides and for the memories it preserves of life and work in the field and laboratory. Historians will increasingly turn their attention to this crucial earth science as the intriguing connections between soils, the environment, and human history become more apparent. Teachers, students, and agriculturalists will also appreciate this detailed account of the Soil Survey.
