| The North-East desert outskirt of Asyut Governorate. Egypt ,i.e. adjacent to both sides of Cairo-Asyut Eastern Desert road is considered a promising area for agricultural .utilization as well as a model for representing some landscape features in the Eastern Desert, Egypt, So ,it selected to be identified within the content of soil geomorphic units ,soil morphological physic-chemical, soil classification and evaluation for agriculture irrigated .Based on the guidelines of landsate data ETM 7(Enhanced Thematic Mapper7) and the geomorphic units approach for the studied area were identified . The investigated area includes the main geomorphic units are wadies, Bajada, Pediplain and Rocky plateau. Seventy –five mini pits were located and studied for setting up the geomorphic boundaries and characteristic of soil map legend. Also, the variation of soil characteristics between the main identified. geomorphic units were represented by twenty soil profiles which to be full morphologically described . According to morphological ,physical and chemical properties the studied soils have been classified and could be categorized into order"Aridisols"and two sub group leveles as Typic Haplocalcids ,and Lithic Haplocalcids and order Entisols which corresponded to Typic Torriorthents .Land capability evaluation of the identified geomorphic units were evaluated to assess the supreme current and potential suitability for giving the maximum out puts.The current land suitability could be categorized into three suitability classes ,i,e moderately suitable (S2),marginally suitable (S3)and not suitable(N), besides eight subclasses (S2sᴤ,sз,s4); (S3sᴤ,sз,s4); (S3s1,sᴤ,sз,n) ;(S3sᴤ,sз,s4,n); (S3sᴤ,sз,s4); (S3sᴤ,s4,n);(N t,s1,sᴤ,sз,s4,n) and (Nt,s1,sᴤ,sз,n) which are suffering from some soil properties i.e. soil texture (s2),soil profile depth (s1),CaCOз(s3);Gypsum(s4) topography (t)salinity and alkalinity (n)as soil limitations with different intensity degrees (slight to severe).By applying the improvement practices for achieving the potential condition ,the suitable classes would be become three classes (S2), (S3), and (N) ,besides seven subclasses i,e (S2sᴤ,s4. S2sᴤ,sз,s4; S2s1, sᴤ, sз, s4; S3sᴤ,s4,; S3sᴤ,sз,s4; S3s1, sᴤ,sз,s4 and N1s1,sᴤ,sз,s4. | ||||
