Overview

This textbook presents a practical approach to teaching basic concepts of soil water and heat flow, with numerous examples and problems to assist the student. Soil water content and soil water potential are discussed and related to water flow and evapo-transpiration. The book also considers the relationships of soil physics to climate and crop production. Heat flow and the temperature of soils are treated as basic concepts that allow estimates of real world diurnal and annual fluctuations.
