Sodic Soils

It is well known that arid-land soils are adversely affected by the presence of sodium, yet only recently has the behaviour of sodium in the soils of humid and subhumid areas, where most of the world's cereal crop is grown, been recognized. This book focuses on the "non-classic" sodic soils, describing the processes of soil degradation resulting from sodium and other deleterious components (such as magnesium), and outlining strategies for ameliorating their effects on soil systems.
