Much recent archaeological research focuses on social forces as the impetus for cultural change. Soils, Climate and Society, however, focuses on the complex relationship between human populations and the physical environment, particularly the land--the foundation of agricultural production and, by extension, of agricultural peoples. The volume traces the origins of agriculture, the transition to agrarian societies, the sociocultural implications of agriculture, agriculture's effects on population, and the theory of carrying capacity, considering the relation of agriculture to the profound social changes that it wrought in the New World. Soil science plays a significant, though varied, role in each case study, and is the common component of each analysis. Soil chemistry is also of particular importance to several of the studies, as it determines the amount of food that can be produced in a particular soil and the effects of occupation or cultivation on that soil, thus having consequences for future cultivators. Soils, Climate and Society demonstrates that renewed investigation of agricultural production and demography can answer questions about the past, as well as stimulate further research. It will be of interest to scholars of archaeology, historical ecology and geography, and agricultural history.

Soils, invaluable indicators of the nature and history of the physical and human landscape, have strongly influenced the cultural record left to archaeologists. In this book, the author addresses each of these issues in terms of fundamentals as well as in field case histories from all over the world.

A concise, inexpensive treatment! Soil Science Simplified, 4/E was written to acquaint students with the basic concepts and scientific principles of soils without the burden of an extensive study. This useful, well-priced handbook includes discussions of soil classification, soil morphology, and soil and the environment. In addition, a chapter on soil surveys helps readers understand soil resources and apply the information presented in soil surveys to managing the soil environment. Outstanding features: 1) provides essential coverage of factors of soil formation; 2) outlines the most current principles of soil taxonomy; 3) provides an assortment of helpful tables, maps, and line drawings; 4) includes an expanded glossary.

The principles and concepts for unsaturated soils are developed as extensions of saturated soils. Addresses problems where soils have a matric suction or where pore-water pressure is negative. Covers theory, measurement and use of the fundamental properties of unsaturated soils--permeability, shear strength and volume change. Includes a significant amount of case studies.
