Salt-affected Soils and Marginal Waters: Global Perspectives and Sustainable Management

This book provides a comprehensive overview of reclamation and management technologies for salt-affected soils and marginal quality waters in India and other countries. It covers scientific appraisal, classification, genesis, and viable technologies, including chemical amendment, nutrient management, and irrigation systems. It also discusses emerging issues such as industrial by-products, salt resistance, submergence tolerance, crop diversification, groundwater recharge, and coastal soil rejuvenation. The book is intended for researchers, teachers, and students in soil science, agronomy, plant breeding, forestry, irrigation engineering, extension workers, environmentalists, and planners.

This comprehensive book delves into the scientific assessment, classification, genesis, and innovative technologies for reclaiming and managing salt-affected soils and marginal quality waters across India and various other countries. It provides a foundational understanding of salts' nature, solubility, and geo-chemical mobility, which form the basis for developing alkali and saline soils and groundwaters in specific agro-hydro-ecological regions. The book comprehensively addresses the reclamation of alkali soils through chemical amendment (gypsum), encompassing pre and post-reclamation water, nutrient, and crop management interventions. It also explores the design and operation of surface, subsurface, vertical, and bio-drainage systems, as well as the mitigation of irrigation-induced saline soils in inland and coastal regions. Preventive measures for controlling salinity and waterlogging are discussed, along with environmental trade-offs. Practical approaches for ameliorating and judicious utilization of saline, alkali, high SAR-saline, and waste waters are synthesized for diverse cropping and agro-forestry systems. Emerging topics such as the use of industrial by-products as amendments for alkali soils, physiological aspects of salt resistance, anatomical and biochemical mechanisms of submergence tolerance, specific ion effects of poor-quality waters, crop diversification, groundwater recharge, rejuvenation of tsunami-affected coastal soils, safety against the occurrence of poisonous gas in tube well pits, paddy straw burning, and other relevant issues are extensively deliberated upon. By integrating scientific principles with field experiences, this book serves as an invaluable resource for research workers, teachers, and students in the fields of soil science, agronomy, plant breeding, and forestry.
