In view of the increasing population and scarcity of land and water resources due to the drought situation in Iraq, effective management of these resources has become an extremely urgent need to achieve sustainable agricultural development. In this sense, an assessment of the Earth's suitability for use is one of the most important tools to help manage these resources appropriately and to use GIS geographic information systems. Four soil profiles were drilled to represent all the different geomorphological units of the land on 15/2/2024, samples were collected from different soil horizons and prepared for laboratory analysis to demonstrate the relationship between the topography and soil data, a soil map was compiled using Arc-GIS 10.3. The results showed that the study area includes four topography features: the Euphrates River floodplain sediments, the valley stream floodplain, the upper valley floodplain and the Jabia upland foothill unit. The results of the evaluation showed through the use of the standard method sys et al 1993 that 15.04% of the land is very suitable S1 for the cultivation of the spelt crop and concentrated in both the Euphrates River Flood Plain Deposit Unit and the Halwat Valley Flood Plain and 24.46% of the land is moderate Suitable S2 concentrated in the Valley's Flood Plain Unit and 60.50% of the land is not suitable within the northern highlands of the forest. The results showed three classes of relevance, as follows: (S2) by (9.89%), (S3) by 22.93% and (N) by 66.77% and the most specific factors for crop cultivation are the gypsum content and organic content
