“…The share of sandy loamy soils is only 17%. Thus, our data do not agree with the concept of the sedimenta tion zonality of the West Siberian Plain proposed by Tonkonogov [24]. According to this concept, in the northern part of Western Siberia up to the boundary with the southern taiga subzone, sandy loamy svetloz ems are the dominant soils.…”

“…Among them are the weak light color of the under lit ter horizon, the inadequacy concerning the classifica tion criteria of the nonsilicate iron distribution in the profile, and the high humus content in the light col ored horizon (>4%). Lastly, according to the data obtained, the texture of the soils of the Sredneobskaya Lowland (83% of the profiles) is loamy, loamy clay, or clay, whereas the West Siberian svetlozems, according to Tongonogov's information [24], are only sandy loamy soils.…”

“…The distribu tion of soddy podzolic soils to the south of the Sred neobskaya Lowland (southern taiga) was implied as one of the arguments in favor of referring the automor phic soils of the northern part of Western Siberia to the type of podzolic soils. In the opinion of some special ists, the data obtained on the composition of the soil profile and soil properties are insufficient to refer the soils of the West Siberian middle taiga to the podzolic type [1,11,12,[16][17][18]24]. Some approaches are con sidered as alternative ones.…”

The morphology of the profile, some chemical properties, and particle size distribution of the automorphic soils developed from lacustrine-alluvial loamy-clayey deposits in the Sredneobskaya Lowland are considered. The soils of the West Siberian middle taiga zone remain poorly studied. A comparison of our data with data on podzolic soils in the northeastern part of European Russia and with diagnostic characteris tics of the soil type of svetlozems included in the new classification system of Russian soils (2004) allows to argue that the studied soils cannot be classified as podzolic soils; most of them also do not fit the diagnostic criteria of svetlozems. The obtained data on the particle size distribution in the studied soils do not agree with the concept of the sedimentation zonality in the West Siberian Plain.

“…It is obvious that sandy covering deposits are an integral component of the loamy-sandy lithological framework of soil-forming sediments within the territory of Northern Eurasia. This fact can be explained by landscape peculiarities and the geomorphological evolution of this territory in the Late Quaternary, which significantly contributed to the wide distribution of three types of glacial and periglacial deposits: moraines, loesses, and sandy deposits [11][12]. These types of covering sediments alternate with a gradual increase in the proportion of sands and moraines to the north of the region, along with a decrease in the proportion of subaerial loams [13].…”

The paper presents the results of the studies devoted to the morphological features and properties of soils representing different geomorphological conditions within the elevated relief forms of the Kondinskaya lowland, with the example of the Kondinskie Lakes Natural Park area. The northern part of the Kondinskaya lowland is characterized by a contrasting and diverse relief, which is generally not typical of the middle taiga zone of Western Siberia. Soil-morphological and-geomorphological methods formed the structural framework of this research. The results showed that Folic Albic Podzols (Geoabruptic) formed on the flat tops of ridges are characterized by a moderate thickness of the E horizon, the largest number of rock fragments, as well as by bedding with loams that have signs of paleocryogenic deformations. Albic Podzols of terraced slopes have more developed E and Bs horizons with large wedge like tongues having depth of about one meter. This group of soils is distinguished by the most diverse structure of the upper part of the profile due to the variability of morphological elements related to biogenic pedoturbations. Albic Lamellic Arenosols occupying steep slopes of the ridges are less developed, and erosional processes often interrupt soil development within this geomorphic position. Albic Gleyic Podzols (Turbic) formed under the steep slopes of high ridges develop over buried Podzols, and often contain charcoal-enriched interlayers in the bottom and middle parts of the profile. Formation of a complex profile, with series of burials, is possibly associated with the activation of erosional processes related to fires and ancient human activity. Study results showed that there is a strong relationship between the lithology on the one hand, and the intensity of podzolization and variability of soil morphological elements related to biogenic pedoturbations on the other hand. The paper contains 5 Figures, 1 Table and 51 References.

“…In recent years, GIS technol ogies have been actively used to analyze soil informa tion together with information about the factors of soil formation; the maps of the areas of the particular genetic soil horizons have been developed [5,27,39], and the cartographic models of the soil cover have been obtained from the maps of the distribution of soil horizons [24], including 3D models [46]. As noted by Tonkonogov [38], the notions of a researcher about soil horizons have a more objective character than his notions about soils. The areas of the genetic soil hori zons carry more definite and precise information about their relationships with the factors of soil forma tion that the areas of the genetic types of soils.…”

The influence of 15 parameters of atmospheric and soil climates on the distribution of 12 genetic soil horizons (humus, eluvial, illuvial, and metamorphic) in the soils of Russian plains was studied. Quanti tative characteristics of the relationships between these climatic parameters and the distribution of soil hori zons were estimated by the rank correlation method. The initial dataset was prepared with the use of digitized maps in the MapInfo program. The results of our study made it possible to estimate the climatic parameters with respect to their impact on the formation of soil horizons. The difference between precipitation and potential evaporation, evaporation, and bulk atmospheric moistening of the soils proved to be the most sig nificant climatic parameters affecting the distribution of soil horizons. These characteristics reflect the redis tribution of moisture under the influence of temperature factors. The weakest correlation with the distribu tion of soil horizons was found for the index characterizing the depth of penetration of temperatures >10°C into the soils.
