DOWNLOAD EBOOKProfiles 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.

DOWNLOAD EBOOKThe Soil Survey Manual, USDA Handbook No. 18, provides the major principles and practices needed for making and using soil surveys and for assembling and using related data. The term ?soil survey? is used here to encompass the process of mapping, describing, classifying, and interpreting natural three-dimensional bodies of soil on the landscape. This work is performed by the National Cooperative Soil Survey in the United States and by other similar organizations worldwide. The Manual provides guidance, methodology, and terminology for conducting a soil survey but does not necessarily convey policies and protocols required to administer soil survey operations. The soil bodies contain a sequence of identifiable horizons and layers that occur in repeating patterns in the landscape as a result of the factors of soil formation as described by Dokuchaev (1883) and Jenny (1941).

DOWNLOAD EBOOKSoil 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.

DOWNLOAD EBOOKThe Australian Soil Classification provides a framework for organising knowledge about Australian soils by allocating soils to classes via a key. Since its publication in 1996, this book has been widely adopted and formally endorsed as the official national system. It has provided a means of communication among scientists and land managers and has proven to be of particular value in land resource survey and research programs, environmental studies and education. Classification is a basic requirement of all science and needs to be periodically revised as knowledge increases. This Second Edition of The Australian Soil Classification includes updates from a working group of the National Committee on Soil and Terrain (NCST), especially in regards to new knowledge about acid sulfate soils (sulfidic materials). Modifications include expanding the classification to incorporate different kinds of sulfidic materials, the introduction of subaqueous soils as well as new Vertosol subgroups, new Hydrosol family criteria and the consistent use of the term reticulate. All soil orders except for Ferrosols and Sodosols are affected by the changes.
