Book Description
This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Book Description
Abstract: Prepared by the Water Quality and Drainage Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE. Agricultural Salinity Assessment and Management, second edition, considers worldwide salinity and trace element management in irrigated agriculture and water supplies. This updated edition provides a reference to help sustain irrigated agriculture and integrates contemporary concepts and management practices. It covers technical and scientific aspects of agricultural salinity management, as well as environmental, economic, and legal concerns. Topics include: nature and extent of agricultural salinity; diagnosis of salinity problems and selection of control practices; soil response to saline and sodic conditions; plant responses to saline and sodic conditions; long-term regional-scale modeling of soil salinity; case study of San Joaquin Valley, California; institutional and salinity issues on the Upper Rio Grande; and viability of irrigated agriculture with expanding space and time. The second edition of MOP 71 is valuable to water professionals, engineers, scientists, practitioners, and educators interested in developing and managing ever more constrained water supplies worldwide

Book Description
Irrigation has long played a key role in feeding expanding populations and is expected to play a still greater role in the future. However, is it sustainable? Can it remain in existence and function continuously and indefinitely? Some pessimists doubt that it is. This volume presents a more positive approach with carefully conditional optimism. It takes the diffuse, voluminous and disparate facts and combines them in a unified exposition. It merges physico-chemical, agronomic, environmental and economic principles into practical recommendations to help ensure the long-term viability and productivity of irrigated agriculture in arid and semiarid regions.

Book Description
In biology, the very big global and thevery small molecular issues currently appear to be in the limelight ofpublic interest and research funding policies. They are in danger of drifting apart from each other. They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due to progressing salinization of arable land is of vital interest for society. Explanations and basic understanding as well as solutions and remedies may finally lie at the molecular level. It is a general approach in science to look for understanding of any system under study at the next finer (or "lower") level of scaling. This in itself shows that we need a whole ladder of levels with increasingly finer steps from the global impact to the molecular bases of SALINITY relations. It is in this vein that the 22 chapters of this book aim at providing an integrated view of SALINITY.
