| Abstract | ||
| Kom –Ombo western plain is located in upper Egypt between longitudes of 32° 38- and 32° 55- 30= East and latitude of 24° 20- 30= and 24°40-40=North covering about(215151.9 feddans).Twelve representative soil profiles of the studied area were chosen on basis of differentiation in the physiographic units,i.e., river terraces, alluvial fans and wadi bottom. The studied soil profiles were classified to eight soil families blonging Aridisols and Entisols orders and four subgroups i.e., Typic Haplogypsids,Typic Haplocalcids, Typic Torriopsamments and Typic Torriorthents. Concerning land suitablity, the studied soils are affected mainly by topography, soil texture and salinity/alkalinity as soil lemitation in variable intensity degrees with moderately and marginally suitable classes. By exciting the suitable soil improvement practices, the potential capability classes assessed were highly and moderately suitable. Land suitability levels were assessed for cultivating group of proposed crops including annual crops (barley, maize, wheat, sesame,soya, alfalfa, sorghum, beans, cabbage and carrots) and perennial ones (citrus, mango and olives). The current suitability was negatively affected by some soil limitations, which require. a major improvement concerning soil, salinity, sodicity and fertility to improve the land suitability to be more profitable potential land suitability as: (1) Soils of river terraces were moderately suitable (S2) for sesame, alfalfa, cabbage, olives and marginally suitable (S3) for barley, wheat, carrots, citrus and mango. (2) Soils of alluvial fans were highly suitable (S1) for Cabbage; moderately suitable (S2) for maize, sesame, alfalfa, olives and marginally suitable (S3) for sorghum and mango. (3) Soils of wadi bottom were highly suitable (S1) for sesame moderately suitable (S2) for maize, alfalfa, sorghum; cabbage and marginally suitable (S3) for barley and wheat. | ||
