Résumé :
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 temperature of soils are treated as basic concepts that allow estimates of real world diurnal and annual fluctuations. BApplied Soil Physics/B offers students and scientists in the area of soil physics and related fields a good understanding of soil water and heat flow. This is the second edition of a proven textbook in soil physics. It presents a practical approach to teaching basic concepts of water and heat flow in the soil matrix, with numerous examples and problems to assist the student.
