Includes references.

The area under investigation bounded by longitudes 32° 10` and 32° 20` east and latitudes 31° 10` and 32° 00` north. Ten soil Profiles reprsentative the logged soils (1, 2), dried soils (3, 4) used Soil for cultivated for 5 years {5, 6) and used soil for cultivated for 10 year (7, 8, 9 and 10). The texture changed from sandy in clay in logged soils and dried soils while it is ranged between, loam and clay in the used soil for cultivated soil. Cation exchange capacity values ranged between 1.2 and 61.79 Cmol/kg and varied according to the variation in the soil texture. CaCO₃ content ranged between 3.89 and 80.00%. O.M content ranged between 0.41 and 5.26% due to the effect of fish pond. Gypsum content ranged between 2.36 and 9.66 %, EC values varied from layer to another and ranged between 15.20 and 400.00 dS/m and the high values in the dried soil, Based on the morphological description and analyical data, the soils classified as Typic Fluvaqients, Typic Haploxerets, Aquic Haplargids, Typic Xerofluvaquents, Typic Haplargids, Typic Xerufluvents.
