Abstract

Soil salinity is one of the factors limiting plant growth and land degradation. The purpose of this study is to apply and access to soil salinity database which are inaccessible in arid and semi-arid regions using laboratory methods and GIS techniques. In this research, an attempt has been made to identify the soil salinity trend and its minerals by digging 8 profiles with an average depth of 1.5 meters and sampling water from 4 points on a transect from the Kenic line to the Playa in Hoz-e Sultan Qom. Soil water samples were taken from each soil profile at the end of the growing season in late Shahrivar and analyzed in the laboratory. The results showed that the trend of salinity changes from Kenic line to Playa is such that chlorides, sulfates, carbonates and finally calcium carbonates are observed, respectively. This trend was significant in Hoz-e-Soltan region. In this study, soil PH range from 6.5 to 8.9, salinity starts from 1.5 ds / m / m2 near the Conic line and increases to 2.30 ds / m2 next to the salt pan. Also, in the study area, sodium (soda) soils, the percentage of exchangeable sodium is more than 15 and the ratio of sodium absorption in the saturated extract is more than 13
