Synopsis The present monograph, first of its kind in the country, written by an agricultural engineer and soil scientist, shows that major part of the problem lands can be utilised for growing several selected crops if managed scientifically. Central Soil Salinity Research Institute has generated a wealth of information on this subject through pilot plant studies in last two decades. Supplemented with other studies conducted in the field and laboratories, the available relevant information has been presented in this monograph so that the latest synthesised knowledge becomes easily accessible to research workers, teachers, students, extension people and planners who can utilise it profitably in the diagnosis and improvement of waterlogged saline soils. Since the irrigation is practised world wide and waterlogging is a inevitable entailing consequence, the technologies and knowledge generated in India, presented herein, should prove immensely valuable to all other countries of the world as well.
