Amazonian soils are almost universally thought of as extremely forbidding. Associated with these are tracts of fertile, dark soils termed terra preta or dark earths. The late Dutch soil scientist Wim Sombroek (1934-2003) was instrumental in bringing the significance of these soils to the attention of the world. This title demonstrates his vision. more...

Submerged soils and the wetlands they support are of huge practical importance: in global element cycles, as centres of biodiversity, in global food production. They are also uniquely interesting scientifically because of their peculiar biogeochemistry and the adaptations of plants and microbes to it.This book describes the physical, chemical and biological processes operating in submerged soils and governing their properties. It describes the transport processes controlling the fluxes of gases and solutes through the soil; the interchange of solutes between solid, liquid and gas phases; reduction and oxidation processes; biological processes in the soil and overlying water; and processes in the roots and rhizospheres of wetland plants. The dynamics of nutrients, toxins, pollutants and trace gases are then discussed in terms of these processes and in relation to wetland productivity and global element cycles.Written by a renowned expert in the field, this work will be invaluable to earth, environmental and agricultural scientists concerned with natural or man-made wetlands, and to advanced undergraduate and graduate studen ts of these topics. more...

This revised publication replaces The Canadian System of Soil Classification (second edition) published in 1987. The changes incorporated in this current publication are based on the work of the Soil Classification Working Group (SCWG) formerly of the Expert Committee on Soil Survey, and continued by the Land Resource Division of the former Centre for Land and Biological Resources Research. more...
