This study focused on genesis, classification, land suitability and land suitability evaluation for agriculture under irrigation and crop suitability of some soils of the River Nile terraces at Khartoum North, Sudan. Three river terraces comprising nine profiles were selected to cover the physiographic positions. Qualitative evaluation was carried out by means of parametric method. The capability index (Ci) was calculated by a weighted average for the upper 100 cm of the soil profile for slope class, texture, soil depth, calcium carbonate status, salinity/alkalinity, and drainage. The results revealed that the soil of the physiographic unit 1(first terrace) was suitable for agriculture (S2) due to limitations of soil texture and moderately drainage, while the unit 2 and 3(second and third terraces respectively) were slightly suitable (S3) due to limitations of poorly drainage (low infiltration rate) and texture (clay). The slope, soil depth, CaCO3 and salinity and alkalinity were not considered as limiting factors in all study area.
