N2  - The present work was carried out to identify land resources for evaluating the possibilities of improving and extending the cultivated areas within the borders of the Siwa oasis using remote sensing and GIS capabilities. The investigated area located in the western desert, and bounded by latitudes 29{u00B0} 05' 00" & 29{u00B0} 25' 00" N and longitudes 25{u00B0} 05' 00" & 26{u00B0} 06' 00" E.. Seventeen soil profiles were taken to represent the soils of the area. Morphological description and soil sampling were conducted during the field work. The soil properties including texture, depth, organic matter (O.M), EC, CaCOR3R, Gypsum, pH, CEC, and ESP values have been determined. The soils were classified as: Typic Torripsamments, Calcic Aquisalids, Typic Haplosalids , Typic Haplocalcids, Gypsic Haplosalids, Typic Aquisalids, Lithic Haplocalcids & Duric Haplocalcids and Typic Psammaquents according to the American Soil Taxonomy. The soil capability classes ranged between class 3 (fair) and 5 (very poor). The most suitable crops for the soils of the area are Cotton, Date palm, Olive, Alfalfa, Barley, Wheat, Maize, Faba been, Soya been, Sugar beet, and Citrus. The suitability for Cabbage, Onion, Rice and Banana is ranging between currently non suitable to permanently non suitable
