A method suitable for laboratory or field application is proposed to extract pore water from a soil and determine its salinity. The pore water is extracted from the soil using a soil press originally developed by Kriukov and Komarova. Once the pore water has been extracted its salinity is determined using a hand-held refractometer with either a parts per thousand (ppt) or refreaction index scale. Using this method it is possible to measure salinity to an accuracy of ±1 ppt. Notes on sample storage and handling are included.
