Description

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.show more

Review quote

"After a critical review of the changing concepts of sodic soils, this book examines their global distribution and the processes involved in sodic behaviour. The role of organic matter and the effects of sodicity on the soil physical properties are described, followed by considerations on fertility constraints to plant production on sodic soils and management requirements. The environmental impacts of sodic soils are then examined, and the effects of sodicity on the use of soils for construction purposes are discussed."--CAB Abstractsshow more
