In this study, spatial variation of soil texture was assessment in the Farahan plain, Markazi province, using Kriging geostatistical method. First, 52 samples from different points in the plain was prepared. Then descriptive statistics for data were determined using geostatistical analysis in ArcGIS 10. 3 software. Then Kriging method was used for determination the spatial variations. Regarding the results of evaluation criteria, Kriging model had an acceptable efficiency in zoning for soil physical properties variations. So that values of evaluation criteria are close to one. On the other hand, spatial correlation was high and in all models it was less than 0. 25. According to the results, soil intrinsic properties, climate and land use were effective in soil texture changes in Farahan plain. It is important to pay the attention land use in soil projects.
