This book presents an in-depth guide to the subject matter and main points of hydrostructural pedology, as theorized for the first time. The authors focus on the underlying concepts, the purpose and role this field plays within agroenvironmental sciences.It is divided into two parts:Part 1 presents the theory behind hydrostructural pedology. The systemic approach applied to the soil is presented, showing how this leads to the thermodynamic formulation of water in the soil's organized medium and to the systemic modeling of soil–water-coupling in natural or anthropic organizations.Part 2 presents the methodology to complement the first part. In it, the authors determine the hydrostructural characteristics of the pedostructure, characteristic parameters of equilibrium state equations and the hydrostructural functioning of the soil.
