| Abstract | ||
| The study Carried out in the Azizya district eastern part of Iraq , in northern of Wasit Province located between latitude 32°36'14.50"N to33°13'56.99"N and longitude 44°52'01.65"E to 45°20'52.70"E . The main objective of this study of depth , salinity and Sodium adsorption ratio of shallow-Groundwater impact on salinity and sodium adsorption ratio of soil by using Ordinary Kriging and remote sensing data, through the application of Spherical Model predicted depths Ground water in the study area, it’s reaching an accurate representation of this model R^2=〖0.9177〗^(**). And applying the Model exponential Exponential Model predicted salinity and sodium adsorption ratio of shallow-Groundwater in the study area, it’s reaching an accurate representation of this model R^2=〖0.8978〗^(**)and R^2=〖0.9998〗^(**)each ofproperties respectively. The diagnosis of salinity and the Sodium Adsorption Ratio in the soil have been using Normalized Difference Salinity Index (NDSI) and vegetative Salinity Index (SI), as was predicted salinity and sodium adsorption ratio of the soilby multiple regression relationship amounted accuracy models resulting R^2=〖0.9600〗^(**) and R^2=〖0.9826〗^(**)for each of the salinity and sodium adsorption ratio in the soil, respectively. | ||
