| Abstract | ||||
| Land evaluation is the first step toward the good agricultural management. Wadi Al-kuf is one of the promising areas for agricultural production in Northeast Libya. The agriculture activities in the Wadi Al-kuf catchment are traditional and inherited. Therefore, the current study aims to assess land resources in wadi Al-kuf, and to evaluate crop suitability maps using integration among soil data, remote sensing data, and GIS. For this purpose, thirty-one soil samples were collected from the study area to represent the main geomorphological units. Topographic maps, fieldwork notes and a Digital Elevation Model (DEM) were used to create the geomorphological map. The study area has been categorized into to nine major geomorphological classes i.e. Alluvial fans, high alluvial plain, high table land, low alluvial plain, low table land, medium alluvial plain, mid-table land, Wadi, and Wadi outlet. The result of land capability showed 19.92% of the total area is classified as “Very High”, 31.55% “High”, 11.94% “Fair”; 24.15% “Poor”; 12.41% “Very Poor”. The main capability limitations are soil erosion risks and rockiness. ‘Also, the results indicated that the most suitable crops in the study area are wheat, barley, sorghum, and alfalfa, (as field crops); Potato, tomato, watermelon (as annual crops), Citrus, olive, apple, grape, and fig (as perennial crops). | ||||
