Used in the past simply as a medium for growing crops or as a filter to improve water quality, the soil has finally come to be considered as a living environment that must be preserved for future generations. A valuable teaching tool, this book provides an overview of the knowledge necessary to understand this new approach to the soil ecosystem and how it works: a place where exchanges and transfers occur, the soil is also a biotransformer characterized by the complexity of the interactions which come into play within it. Using specific examples, it shows how certain practices used by man can suddenly threaten an established balance: salinization, erosion, contamination, etc., and offers solutions for improved soil management. Based on secondary school teaching programs in Life and Earth Sciences, this book is specifically aimed at teachers; it will also provide students with a good initiation into higher education programs in the sciences.
