Soil is an important aspect of rangeland greatly affects vegetation types and sites characteristics. These characteristics could help to understand the interactive relationships among the topographic, soil feature, vegetation composition for better management capacity. Factors that affect soil development are: climate, living organisms, topographic relief or landscape position, parent material and time (Roselleet al, 2011). This study was conducted in North Kordofan State in the semi-arid areas of Sudan to investigate the influence of range site characteristics on management prescriptions. The field data compared three rangelands sites in the study area, Jebel Kordofan, Um Glugi and Demokeya. The results of the present study showed that there were remarkable variations among selected sites in plant cover, biomass productivity and plant density during the growing season in the two study periods 2010/2011and these differences attributed to the influences of soil types as sites specific features as with the case of existence of some plant species that are more attractive to animals resulting in more intensive grazing (Cenchrus ciliaris and Aristida spp). Results indicated that Demokeya site exhibited highest plant cover and biomass production and Um Glugi had highest plant density in the two seasons. These results demonstrated that soil types in semi-arid region have an effect on distribution of moisture and nutrients resources, this effect also are expressed in vegetation attributes between rangeland sites and it is play an important role in range management to both the kind and amount of forage produced and the type of management options. This study provides baseline information regarding characteristics in these rangeland sites. Further investigations are required in-depth understanding these characteristics to progress toward sustainability.
