Abstract: Wadi Surd is one from the largest and important wadis in the south-western side of Sinai Peninsula due to its promising soils and water potentialities. The current work aims at study the geomorphology, Pedology and evaluation of the soils of Wadi Sudr. The geomorphological studies indicated that, there are four main geomorphologic units in the area. These units are dry Sabkha, Out wash plain, Oolitic sand and Delta plain. Ten Soil profiles were selected representing these units. The soil profiles were morphological described and samples were collected for physical and chemical analyses. According to Soil Survey Staff (2014), the obtained results revealed that all studied soils could be categorized into order Aridisols. These soils are classified up to family level under four sub-greats namely, Gypsic Haplosalids, Calcic Haplosalids, Typic Haplocalcids, Sodic Haplocalcids. The studied Soils were evaluated for their suitability for agriculture use. They categorized into two classes namely, marginally suitable (S3) and not suitable (N). These soils are suffering from limitations of texture, carbonates, gypsum, salinity and alkalinity with different intensity. The severity of these limitations could be corrected by further land improvements. Accordingly, the potential suitability of the most studied soils could be improved to moderately suitable (S2) and marginally suitable (S3). Moreover, the suitability of 11 main crops in these soils was evaluated in the current and potential situation. The results indicated that these soils are not suitable for growing these crops in the current situation. The potential suitability of the soils for these crops could be improved according to the satisfaction conditions between soil properties and crops requirements
