Abstract

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.
