The main attention is focused on the change in the carbonate status of soils. According to the results of the study, it was found that the transformation of both types of soils formed on different rocks obeys a single trend. Carbonates in Chernozems during their stay in fallow are washed down the profile; stable forms of carbonate pedofeatures gradually disappear. The content and stocks of carbonate carbon in the 0-200 cm layer in Haplic Chernozems (Aric) decrease by 27.5 t/ha by 25 years of fallow state. In Сalcaric Phaeozems (Aric), changes in the carbonate status are less pronounced; nevertheless, it was found that in the arable soil on the fragments of limestone, secondary carbonate films in the form of acicular calcite...

Research paper thumbnail of Soil salinization processes in the impact zone of mineralized water discharge by the case study in the Yaroslavl Volga region, Russia

Nevertheless, the occurrence of salt-affected soils under humid climate is evident as a result from another factors but not the climatic one. Soil salinity in these landscapes is caused by anthropogenic salinization. The objective of this study was to identify types of chemical composition and salinity level of soils forming within the impact zone of artesian water discharge. This paper also provides determining the degree of contrast to adjacent non-saline soils and salt contamination boundaries. Soil and water samples were collected from three sites located in the Yaroslavl’ region, the Upper Volga. Sampling was released in June 2017. In the Upper Volga region high-mineralized water rises from saline aquifers via abandoned exploration wells drilled in the 1960s. These soils are found under an average annual rainfall of about 500-700 mm in taiga zone. This type of c...

Research paper thumbnail of Dynamics of soil salinization in the Nero Lake depression (Upper Volga) in connection with the latest climate change

In this study, an attempt to analyze the soil record of recent climate changes was made. An example of soil evolution induced by climate change was studied on hydromorphic saline soils in the nature reserve of the Varnicy Saline Spring. In a humid climate, soil salinization occurring in discharge areas can quickly change in response to the changed hydrothermal regime because of close relationships between climatic conditions and groundwater systems. In a poorly drained depression, we could observe an increasing soil salinity and developing hydrogenic accumulation of salts, whereas the groundwater salinity was stable.

When preserved these features serve as direct or indirect indicators of the past cryogenic conditions. Transformation of soil material on macro- and microscale belongs to the direct indicators whereas gleying in the well-drained positions, conditioned by the permafrost waterlogging is an indirect indicator. A variety of these features observed in the paleosols to the north of the European and West Siberian Loess belt was used by the authors to reconstruct the cryogenic environments of the late Pleistocene.

This resulted from local aeolian transport, with the source material derived from the rewinding of marine sediments. They are enriched in aggregates of Chocolate clays and glauconitic grains of a fine sand-course silt size and have similar contents of clay minerals. The high salinity of similar types evidences marine genesis for both Chocolate clays and source material for loess sediments. Clay fragments of a sand and silt size are responsible for the heavy texture and high gypsum content of loess. The study of soils with the focus on micromorphology and clay mineralogy allows the identification of the complex character of a shift from marine to sub-areal sedimentation. This shift was accompanied by sho...

Research paper thumbnail of Paleolandscape Reconstruction Based on the Study of A Buried Soil of the Bronze Age in the Broadleaf Forest Area of the Russian Plain

Geosciences, 2019

Late Holocene landscape evolution at the southern frontier of the forest belt of European Russia ... more Late Holocene landscape evolution at the southern frontier of the forest belt of European Russia is studied based on detailed morphological, analytical and microbiomorphic research of a soil chronosequence that included a surface soil and a soil buried under the Bronze Age kurgan. Both soils (Folic Eutric Cambisols) are formed on similar geomorphic surfaces in the same parent material and in close proximity to each other. The soil morphology and the key analytical features are controlled by low-reactive parent material and imply close similarity of the present landscapes and those of the Bronze age. At the same time the morphological features show that the buried soil was influenced by the phase of weak aridization, which led to the formation of a dark mull humus horizon. Microbiomorphic assemblages (phytoliths, pollen) support the earlier conclusion that the soils of the study area had being developed mostly under forest vegetation.
