The features of similarity and difference in the microstructure of bogharic and irrigated soils of kastanozem-solonetz complexes of the Pristavropolskaya sloping plain

A comparative analysis of microspecificities of agrogenic soils of solonetzic complexes of inclined plain was conducted to create trends of elementary soil-forming processes under different types of anthropogenic changes (for plowing and irrigation). The task is solved with the help of Olympus BХ51 polarization microscope equipped with Olympus DP26 digital camera and Stream Basic software, which allows us to visualize the results of modern and/or relict process better. The investigation objects are the soils of kastanozem-solonetz complexes of the Stavropol inclined plains of the bogharic and irrigated area. Common microspecificities for all studied soils are numerous carbon particles, humus-ferruginous micronodules and ring-shaped orientation of fine-silt and fine-sandy silicate particles. The first two microspecificities allow us to propose there a weak manifestation of the quasi-gley process that probably was inherited from the pre-agrogenic development of the investigated soils...
