| Abstract | ||
| Is important in determining the method of taking samples in the field to know the differences of spatial characteristics of soil and soil salinity for the purpose of characterization of any of these qualities and distribution in specific way.The objective of this study is to create amap of the distribution of soil salinity in the soil horizons, as well as knowing of the soil variability Kriging theory has beenused to find out the variation by using thesemivariogram through GIS program , and sites were selected in termsof AlHuar and Alhendia region in Karbalaprovince to complete the search.The study results showed that the distribution of salinity was according to classes of salinity S1 ,S2 ,S3 and S4 .The class has S1the least in terms of space and focus on the horizon Ap , whereas class S3hasthe largestarea in all horizons. Results also showed that soil salinity varies from one horizon to another when Ap horizon and mostvariability C2while C1 horizon the leastvariability due to agriculture operations thatoccur in the upperhorizons and exposure to environmental conditions directly , highground water and movement of salts bycapillarity , and results showed that the prediction values or absorption to soil the salinityin the sites studied were variability for all prospect. | ||
