Microbial composition of water, sediment, and soil in different sampling sites of the Old Course of Yellow River (Shangqiu Section) at the genus level

For each sampling site, 1 water sample, 1 sediment sample and 9 soil samples were collected in triplicate. Within each soil site, 3 sampling points were taken at distributed straight-line distances of 10 m (s10), 50 m (s50) and 100 m (s100) from the riverbank.

Around each point, 3 random soil sub-samples were collected using a plastic spoon from the corresponding depths (cm) of 0–20 (top), 20–40 (middle), and 40–60 (bottom). A-Fanzhuang Village, C-Linqi Reservoir, D-Forest Park, F-Liuyang Village, w-Water samples, s-Sediment samples, s10-Soil samples 10 m far from the riverbank, s50-Soil samples 50 m far from the riverbank, s100-Soil samples 100 m far from the riverbank.
