Abstract: The aim of this investigation is to study the characteristics of Al-Bawoiti soils for evaluating their capability and suitability for growing main crops using Remote Sensing (RS), Geographic Information Systems (GIS), and Sys, Model. Thirty-one representative soil profiles were selected. The profiles were morphological described and samples were collected representing the vertical variation for different laboratory analysis. According to the RS and GIS works three geomorphic units are recognized. These units are depression plain (18.06%), Aeolian plain (28.9%), and Pediplain (53.04%). The correlation between geomorphic unit and soils was carried out and then the soil maps where created using the ArcGIS 10.4.1 software. Based on the soil characteristics, the studied soil were evaluated according to their suitability for agriculture. In the current situation, they categorized into their capability classes namely, moderately suitable (S2=1.88%), marginally suitable (S3=85.87%), and not suitable (N=12.24%). These soils are suffering from limitations of texture class, salinity and alkalinity, topography and soil depth with different intensity degrees (slight, moderate, and severe). The severity of these limitations could be corrected by future land improvement according the potential suitability of the most studied soils could be improved to highly suitable (S1=0.2%), moderately suitable (S2=25.97%), marginally suitable (S3=73.53%), and not suitable (N2= 0.3%).Moreover, the suitability of 18 main crops in these soils was evaluated in the current and potential situation. The potential suitability of the soils for these crops could be improved according to the satisfaction conditions between soil properties and crops requirements.
