Research on Soil Seed Banks of a Rangeland Area White Nile State, Sudan

At the study site, three soil depths (0 to 5, 5 to 10, and 10 to 15 cm) were selected, and the number of live and dead seeds for each were counted in the soil seed bank. The results of the investigation were as follows: In comparison to the lower soil depths (0 to 5 and 5 to 10 cm), the seed bank density was higher in the upper soil depths (0 to 5 and 5 to 10 cm) (10 to 15 cm). The seed density was discovered to be decreasing as the depth was increased. The density of live seeds ranged from 1015 to 5371 seeds/m2, while the density of dead seeds was 3215 to 6957 seeds/m2. Grass species such as Schoenefeldia gracilis, Brachiaria spp., Dactyloctenium aegyptium, and Aristida spp. were the most common, with Schoenefeldia gracilis, Brachiaria spp., Dactyloctenium aegyptium, and Dactyloctenium aegyptium, and Aristida s Panicum turgidum, Euphorbia aegyptiaca, and Cyperus rotundus were among the dominant species to which the dead seeds belonged. The percentage of dead seeds was also higher than that of live seeds, according to the report.
