Analyses of the soil: water extract of 1:5 and soil solutions represent a traditional method of soil salinity assessment in Mongolia and the countries of the Eurasian Region. At an international level, there is a widely used salinity assessment method based on the specific electrical conductivity of saturated soil-paste extracts. Electrical Conductivity (EC) of soil water extracts is commonly used to access soil salinity because it is an easier method than the standard saturated paste extract (ECe). However, it is essential to convert EC of soil water extracts to ECe because plant response and salinity remediation are based mainly on ECe values. The study aimed to identify soil EC, anions and cations in soil samples from Gobi and Desert area. In our study we found mean of EC ds cm-1 was highest in Takyr soil and lowest was in Yermic Calcisols. Salinity Parameters increased with the depth. At 30-50 cm and 50-100 cm depths, EC increased 3-7 fold compare with the surface depth. Soil electrical conductivity showed weak (R2=0.16, 0.19, 0.21, 0.26) correlation with bicarbonate, sulfate, magnesium and potassium but strong (R2=0.92, 0.84, 0.61, 0.91) correlation with dry residue, chlorine, calcium and sodium respectively.
