Abstract EN

Done studying the variability of the soils And the heterogeneity of the characteristics of the soils of the Euphrates, where 6 boreons were described and described the horizons of the pidoons as morphological and fundamental, as well as obtaining random samples on four equal depths 25-0 cm, 50-25 cm, 75-50 cm and 100-75 cm.

The results of spatial heterogeneity Turbidity and Spatial Distribution Maps The heterogeneity of all the characteristics of chemical faecal soil is indicated by the results.

The results indicate the variance of the horizons in the moving distance that describe the heterogeneity of the chemical properties, Electrical conductivity of EC Ranging between 0.48-5.46 and gypsum Ranging between 0.15 - 4.61 qualities more heterogeneous, and then followed by organic matter Ranging between 0.27-4.50 and CEC Ranging between 18.66-38.42 .

The least heterogeneous properties were soil pH Ranging between 7.05- 7.62, followed by calcium carbonate Ranging between 284.28 - 438.71, where the range was high The results showed that the appropriate model describing the heterogeneity of the chemical properties was the circular model, the appropriate model for describing its variation by 54%, followed by the spherical model of 43% and the gussin model of 4%.

The soil of the study according to the modern American system 2014 is classified into two levels: Entisols and Mollisols
