Popis: The studied area is located between Latitude 300 06 59\ to 300 1256\North and Longitude300 36 31\ to 300 45 44\ East covering about 151km2. The object of this study is evaluate the physiographic soil units includingsoil classification and its suitability for agriculture.The physiographic units of Wadi El- Farigh soils were attributed as:(1)Dry Valley including soil taxonomic units;a-TypicTorriorthents, coarse loamy, mixed, hyperthermic.b- TypicTorriorthents, sandy over loamy, mixed, hyperthermic.c- TypicTorriorthents, fine loamy, mixed, hyperthermic.d- TypicHaplocalcids, sandy, mixed, hyperthermic(2)Alluvial Terraces including soil taxonomic units;a-TypicTorriorthents, fine loamy over sandy, mixed, hyperthermic.b- TypicTorriorthents, coarse loamy, mixed, hyperthermicc-TypicTorriorthents, sandy, mixed, hyperthermic.(3) Wadi plain including taxonomic units;a - TypicTorriorthents, fine loamy, mixed, hyperthermic.(4)Piedmont plain including taxonomic units;a-TypicHaplocalcids, loamy skeletal, mixed, hyperthermic.Land suitability of physiographic units could be categorized into threeclasses as; highly suitability (S1) for some soils in Wadi plains, moderatelysuitability (S2) for dry valley and Wadi plains and marginally suitable (S3) forTerraces and Piedmont plains.Land suitabilities were sorted by matching rates of its characteristicsand limitations with crop water requirements to give the maximum output.The proposed crops are classified as potential land suitability as;A)Highly suitable (S1) in dry valley and wadi plains for olive.B)Moderately suitable (S2) in dry valley and wadi plains for wheat, barley,maize, cotton, sesame, sunflower, sorghum, onion, watermelon, citrus,guava and mango. While, it is moderately suitable in terraces and piedmontplains for olive, sesame and sorghum.C)Marginally suitable (S3) in dry valley and wadi plains for banana. While, itis marginally suitable in terraces and piedmont plains for wheat, barley,maize, sunflower, onion, watermelon, citrus and mango.D)Not suitable (N) in terraces soils for tomato and banana.
