This study was conducted in Elobied North Kordofan at Am Kass rainy season grazing area (Makhraf), located about 25Km from Elobied town. The study aimed to assess variation of soil seed bank in different soil of rangeland. The sampling assessing rangeland health (soil seed bank) for the study was based on identifying the main rangeland sites based on soil type (sandy and gardud soil). Data collected using transects sample methods. Soil samples were taken to assess soil seed bank for rangeland health assessment. According to main findings at Sandy and Gardud soil has there were variations between the two sites in soil seed bank which was higher in gardud site compared with sand, the live seeds and dead densities were (2067 seed/m2, 1728 seed/m2/5 respectively) whereas found low at sandy site, the live seed and dead densities were 610seed/m2, 676seed/m2 respectively.The dead seeds included (Abutilonfigrianum, Echinocloacolonum, Abutilonanagolensis, Abutilonanagolensis, Ocimumbasilicum) and dominant live seeds in gardud (Abutilonanaigolensis, Echinocloacolonum, Zaleyapentandra, Abutilonfigrianum, Sesamumalatum) and dead seeds included (Echinocloacolonum, Cenchrusbiflorus, Ocimumbasilicum, ZaleyapentandraandSidacordofolia).
According to the results the study recommended that to concern the variation of soil seed bank and different soil types in rangelands management strategies.
