This study focused on the assessment of land degradation in University of Khartoum (Shambat Area), Khartoum State, Sudan. Through mapping and monitoring the changes that occurred in the soil properties, due to drought and mismanagement. The study attempted also to update some information in the study area such as chemical properties using different methods of data transformation and analysis such as: Soil analysis technique, GIS and remote sensing analysis.
The research was based on the data and information deduced and extracted from soil survey data, soil analysis, and remote sensed data, in addition to fieldwork verification and other sources. The study covered an area about 300 Acers.
Soil analysis indicated that soil degradation was taken place in the study area specially the top northern and southern parts of the area which were affected by some buckets of salinity, while the north-eastern and south- eastern parts were affected by sodicity buckets.
The study showed that there was a hardpan (Average bulk density of soil, 1.9 g/cm3) at subsurface layer (30-60 cm) and subsoil layer (60-90) that impedes the water infiltration and crop growth since tilling is done only in the surface soil to the depth of 25 cm (infiltration rate < 0.07cm/hr.). Evaluation of soil properties and degradation hazard, According to framework of the land suitability (FAO, 1976) revealed that the soil of the study area is moderately suitable (S2) for agriculture.
