Written for scientists without a background in soil science, comprehensive in scope, this book provides basic and advanced coverage of hydric soils from Florida to Alaska. It begins by examining the basic concepts, processes, and properties of aspects of hydric soils that pertain to virtually any hydric soil and providing a general overview and important terms and concepts. The book then covers the soils in specific kinds of wetlands and the different functions they perform. It emphasizes special wetlands conditions such as soils composed of sand, organic soils in northern North America, prairie wetlands, wetlands in saline situations, dry climates, and wetlands with modified hydrology.
