Abstract:
The aim of this study was to evaluate the land suitability of some River Nile terraces for crop and fruit production at Khartoum North, Sudan. For this purpose, nine soil profiles from three river terraces were selected to cover the different physiographic positions. The land suitability evaluation for annual crops and fruit tress was carried out by matching site conditions with the crop requirement with respect to the characteristics such as: climate condition, topography, drainage, texture, CaCO3, CEC, % O.C, salinity and alkalinity. The suitability for crops, vegetables and fruit were divided into excellent, good, moderate, weak and not suitable. The soils of the study area were classified into: Typic Torrifluvents (unit 1), Entic Haplocambid (unit 2) and Typic Haplocambid (unit 3). The study showed that the soils of the three units were moderately suitable (S2) due to limitations of inundation, fertility, wetness, erosion, and physical limitations. Results indicated that the suitability of units 2 and 3 were weak for Arachis hypogeal L, Alluim cepa, Vitis spp, Citrus sinensis and not suitable for Phaseolus vulgaris.
