Summary Vertisols, one of the eleven established soil orders, are clay soils with unusual and interesting properties. They cover more than 350 million hectares of land in the world and in tropical Africa alone there are over 100 million hectares. Because of their very small particle size and high surface area, these soils have higher physical and chemical reactivity than other soils. Their interaction with agrochemicals/industrial wastes, has been, increasingly, the subject of research especially in the last two decades. Vertisols create special problems when used for engineering purposes. This book is intended to provide comprehensive and state-of-the-art information about Vertisols worldwide. Special attention is given to the use and management of soils such as fertilizer use, crop selection, soil tillage, water restriction on land including irrigation, and soil erosion. A special chapter has been added to deal with geotechnical engineering of Vertisols. Vertisols have great potential for agricultural production but many, especially in the developing world, are underutilized due to a lack of understanding regarding their behaviour and management. This book is written by leading scientists worldwide. It is expected that this monograph will be of great use to soil scientists and agronomists, graduate and senior graduate students. Improvement of their management may solve the current food deficiency in the world
