Abstract

The area under investigation bounded by 25° 16- - 26° 7- E and latitudes, 29° 7- - 29° 21- N; and extended for about 70km in east-west direction, with a width of 7-10 km. The dominant texture class varied from sand, loamy sand, sandy loam; and silt loam. pH values ranged between 7.4 and 9.3. CaCo3 content ranged between 1.6 and 42.3%. O M values varied from 0.1 and 2.6%. Gypsum content ranged between 0.01and 5.04%. EC values varied from 0.5 and 98.3 (ds/m). The CEC values varied from 1.9 and 35.09(mq/l). ESP values varied from 6.3 and 36.4%. Nitrogen values varied from 11.1 and 55.9(ppm). Phosphorus values varied from 2.8 and 60.8(ppm). Potassium values varied from 186.6 and 933.1 (ppm). Based  on the american soil taxonomythe soils were classified as Typic Torripsamments, Typic Psammaquents, Typic Haplosalids, Typic Aquisalids, Gypsic Haplosalids, Calcic Aquisalids, Typic Haplocalcids, Lithic Haplocalcids, and Duric Haplosalids. The soil capability varied from Good ,  Average ,  Low ,and Extremely low. Soil suitability for alfalfa, green pepper, onion, maize, barley, sugar cane, tomato, wheat, and wheat ranged between marginal and unsuitable except for olives, and date palm, ranged between moderate and unsuitable.
