Dataset on chemical properties, macro and micromorphological features of forest - steppe native soils in 2022 (Oka-Don plane)

All images are organized into six folders, each named according to the number of the soil pit and replication. The folder “p.S1_n1” contains 93 images, the folder “p.S1_n2” contains 42 images, the folder “p.S1_n3” contains 50 images, the folder “p.S2_n1” contains 58 images, the folder “p.S2_n2” contains 53 images, the folder “p.S2_n3” contains 71 images. The images are named based on the following convention: the pit number comes first, then the number of replication, then the sampling depth, then the number of the field of vision, and then the type of light (plane polarized light (PPL), cross-polarized light (XPL), reflected light (RL)).

These data are valuable for evaluating dynamic changes and trends in soil properties influenced by changing climate patterns and are valuable for soil scientists studying black soils and general soil genesis. Other researchers can reuse these data for modelling soil substance flows, both vertically and across the landscape. The data significantly contribute to a better understanding of the pedodiversity within the forest-steppe region.
