The aim of the study was to scan land suitability for Agriculture i.e. land utilization types which is, partly described by the FAO (1976), the fitness of a specific tract of land for a specified kind of land use under a stated system of land management, but mainly and fulfilled by the results of the subjective study. There are two specific objectives: I. Soil survey: soils characterization - soils classification according to the USA Soil Taxonomy - soils database (Profiles and routine observations with Excel) - soils mapping (scale 1:25,000). II. Land evaluation: physical suitability of the soils of the project area for irrigated agriculture according to Sys et. al. (1991) for a number of selected crops, commonly grown in the surrounding areas. The obtained field and laboratory investigation and results have introduced and then evaluated a three main soil groups (Typic/Litic Torriorthens, Litic Haplocamids and Typic Haplocamids). Aiming the most adequate cropping pattern and crop rotation models of the North Sudan land areas, based on detailed "Land and Crop suitability models optimization". By the use of these models, a different Farms, Vegetable and Orchards-Fruits crop varieties, have been evaluated and finally chosen and presented as a general cropping management use, within the sustainable and integrated Agriculture production.
