Abstract

This paper compares different procedures for soil salinity analyses to determine
electrical conductivity: saturated paste extract (ECe), xed soil:water
ratio extracts EC1:1 and EC1:5, and soil solution paste prepared with 1:1 soil:
water ratio and measured directly in the solution above the paste (ECp),
apparent electrical conductivity (ECa) of a soil down to a depth of 0.75 and
1.5 m measured by electromagnetic device, and laboratory analyses for total
dissolved solids (TDS) and ion composition. Conversion factors between
these different methods to estimate salt content of soils are presented and
can be applied for the predominant textures in the Khorezm region in Uzbekistan.
The procedures described allow easy follow-up and replication of
the approach
