Abstract EN
The study area was chosen in the Iraqi alluvial plain, as the East Haffar project was chosen in the Diwaniyah governorate and on the left side of the Tigris River.
The project lands are confined between longitudes 40° 44' to 44 ° 50' east and latitudes 31° 40' to 31° 50' north.
The project area is about (50, 000) hectares for the purposes of studying the accuracy of soil maps.
A geographical correction of the project map was made on a visual satellite after that, a path was determined on the map, then soil samples were taken every 100-500 m according to the size of the map unit and for different depths according to the variation of the texture.
The coordinates were taken by the GPS and four depths.
The study included the following characteristics: the content of clay, sand, and silt, as well as the electrical conductivity pH, SAR, ESP, and EC.
The accuracy of soil maps was studied in two traditional and predictive methods using traditional and geological statistics, and the results were as follows: There is a difference in the accuracy of traditional and predictive soil maps when using geological statistics, as the accuracy of the traditionally constructed soil maps was 80.08% .
Then the accuracy of the map that was constructed in a predictive manner using GIS and the Krging method was 81.74% , but the IDW method, which outperformed the previous two methods had have an accuracy of 88.26% .
