The morphologic, physical, mineralogic and chemical specificities of solonetzic process occurrence are studied in the arable layer from the non-meliorated solonetz for 50-year period of its post-agrogenic evolution. The mineralogic analysis of the separate grain fractions (<1, 1–5, 5–10, >10 mm) from microhorizons was conducted. Morphologically these grain fractions were specific for the crust horizon. It is revealed that the silty fraction of the soil forming clay loam is dominated by unordered complex mica-smectite formations, and in lesser concentrations there occur hydromicas, chlorites and caolinite. The former arable layer in the profile is characterized by the different correlation of the same mineral phases than in the other layers. The content of silty particles is dominated mostly by hydromicas. It is revealed that in all fractions <1 mm the content of quartz, potassic feldspar and plagioclases is determined. There is also observed relative decrease of chlorite and caolinite in the former arable layer comparing to the lower layers of solonetz from the old layland. The conducted studies showed that after 50 years of postagrogenic evolution the deformation of mineralogical indices from the former arable horizon occurred. The most significant changes occurred within the surface microhorizons AJ1el and AJ2el (within the upper 3 cm). There is observed a depletion by silty fraction, and with it, by mica-smectitic formations. There is also observed relative enrichment by fine-dispersed quartz, plagioclases and potassic feldspars. The uppermost microhorizon AJ1el contains the highest amount of quartz and the lowest amount of chlorite and caolinite. In the lower part of the arable layer (Psn,pa) the insignificant increase of silty fraction content and mixed layer mica-smectites is revealed. The obtained specificities of differentiation of mineralogic composition of initially non-meliorated soils within the former arable layer stipulate about the initial states of solonetz microprofile forming during the 50 years of its postagrogenic evolution.
Keywords: solonetzes, evolution of soils, clayey minerals, mixed layer formations, profile distribution.
