Book Description
The method is a rapid, simple procedure for the determination of soluble salt in soils. The electrical conductivity of the supernatant liquid is used to approximate the soluble salts present in the soil pore fluid. The method is not intended to be precise; however, on a relative basis reliable comparisons can be made. At any one location, the method permits very small changes in pore fluid salt concentration to be accurately measured. For a detailed discussion of the method, the reader is referred to "Methods of Soil Analysis, Part 2," Section 62, published by the American Society of Agronomy in cooperation with ASTM.

Book Description
This manual presents procedures for performing advanced laboratory tests on fine-grained soils. It covers characterization tests, which determine soil composition and quantify the individual components of a soil, and behavioral tests, such as the Atterberg Limits tests that demonstrate how the fines fraction of a soil reacts when mixed with water and the Linear Shrinkage Test that demonstrates how much a soil shrinks. The material goes beyond traditional evaluation of basic soil behavior by presenting more advanced laboratory tests to characterize soil in more detail. These tests provide detailed compositional characteristics which identify subtle changes in conditions and vertical variations in the soil, and which help to explain unusual behavior. A unique compilation of information on key soil tests Combines characterization tests with behavior tests The book suits graduate students in geotechnical engineering, as well as practitioners and researchers.

Book Description
Excerpt from An Electrical Method of Determining the Soluble Salt Content of Soils: With Some Results of Investigations on the Effect of Water and Soluble Salts on the Electrical Resistance of Soils The moist soil is thoroughly mixed with a Dover's egg'beater, securely fastened to a sh elf or table, to distribute the water uniform throughout the mass of soil. The soil must not be mixed with the hands, as the salts from the hands are liable to Vitiate the results, especially in a warm room where the hands are perspiring freely. The soil should be put in a round-bottom bowl or in a heavy glass cover, such as is used in the laboratory to protect apparatus and specimens from dust. With clay soils especially it is well to empty the soil out of the bowl and pour it back again once to insure thorough mixin g of the water or solution throughout the mass of soil.

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.
