Abstract EN
This study is concerned with the spatial variability of some soil properties such as pH and electric conductivity (EC).
Besides that, the study depicts the spatial variability of some ions (cation and anions) of the Dead Sea (DS) soil namely, Na \ CI", Ca2+, K+, Mg2+, HC03- N03- and SO4".
The geostatistical techniques show similarities among the semivariogram models.
All semivariogram models are constructed in this study in order to understand the behaviors of spatial distribution.
The spatial distributions of soil properties show differences from site to site which is expressed in terms of angles, where the larger the angle the weaker the correlation.
The semivariograms show two regions, each one represents different type of soil.
The first region starts from the DS till 80 m ; except Mg semivariogram model which is extended up to 60 m.
This region is characterized by larger correlation angles, which consequently reflects lower correlations among the samples of each semivariogram model in this region.
The second region started from 80 m up to 1000 m.
The angles of correlation in this region are closed to each other that reflect better correlation among the samples of this region in each model.
An estimation of pH at pivot site shows good correlation.
The result is calculated with relative error of about 2 %.
The standard regional dependence function (SRDF) and the radius of influence figures are constructed in this study in order to understand the interrelations among the distance and the variation of soil salinity.
