Mapping and spatial distribution of the natural and transformed soils of Osa river basin (Irkutsk region)

The soil cover of Osa river basin is described in the article, its variety caused by features of a geological structure, relief, climate, vegetation and anthropogenous impact is revealed. Set of factors of soil formation which gives prerequisites for forming of special types of the soils which aren’t fitting into traditional representations of zone types of a taiga and forest zone – chernozems, dark-humic and other soils under steppe vegetation is studied. In total three trunks, nine departments, 27 types and 46 subtypes of soils are allocated. It is established that the main area (more than 7 0 %) is provided by the soils entering into departments of the accumulative and humic, organo-accumulative and textural differentiated soils, agrozyom, and the insignificant territories are busy with full-height types of soils of structural and metamorphic department, litozyom, abrazyom, alluvial. 37,3 % of the general territory of a research occupy agricultural holdings, from them about 12,8 % are used now, 87,2 % are in abandon condition. The map «Soils of Osa River Basin» is provided in the article.

Aim. To assess the interrelations of chemical and physical-chemical parameters of soil cover properties with climatic factors of soil formation in agricultural landscapes of the Central Chernozem Region (CCR) of Russia.Materials and Methods. The research was carried out using a systemic analysis of the complex of agroclimatic and soil parameters. Soil properties were assessed by the weighted average characteristics of arable soils for the areas of the Central Chernozem Region. Hydrothermal conditions were taken into account by rainfall, temperature and the amount of active temperatures for the period 1960-2000.Results. Estimated excess of annual precipitation (440-640 mm) over evaporation (407-500 mm) in the average annual cycle ensures the formation of total runoff and soil washability in the amount of 40-150 and 17-104 mm. This determines soil acidity (pHKCL, R2 = 0.36...0.73). Optimal conditions of humus accumulation are formed when the humidity factor is 0.8-0.9. Mesorelief is a factor of spatial heterogeneity of the total soil composition with which 85% of physical-chemical properties and up to 70% of nutrient availability are associated.Conclusion. The differences in the hydration of the territories both at the scale of the CCR and local levels determine the intensity of geochemical runoff, the oxidation-reduction regime and total chemical soil composition which constitute the basis of heterogeneity in the content of organic matter, acidic-base and other properties.

Genesis Of Soils

The aim of the study. To study the properties and genesis of natural soils of forest-steppe areas of Balagansk steppe. Location and time. The environs of Balagansk settlement in the Balagansky district of Irkutsk region, 2013-2018. Methodology. Combined field and laboratory studies of soil cover and soil properties using soil-morphological, pedo-lithological, climatostratigraphic, botanical, geological-geomorphological and comparative geographical methods, as well as various physical and chemical analyses. Main results. The study of soil properties of the Balagansk’ forest-steppe and assessment of their classification position revealed the basic regularities of geographical distribution of soils. In steppe areas of the studied region clay-illuvial and textural-carbonate chernozems were formed. The forest vegetation favoured the developed of residual-carbonate gray, dark gray, gray and dark gray metamorphic and burozemic soils; the floodplain areas are predominantly occupied by gley soils and dark-humus gleic soils. Conclusion. The study of soil and vegetation cover of the Balagansk’ forest-steppe showed that soils were developed on the eluvium-deluvium of carbonate Cambrian red-colored siltstones and loess cover and have sufficiently high natural fertility and ecological and resource potential. The soils of the investigated area are characterized by a large variety and complex polygenetic structure of the soil profile, which reflects the change of soil formation’ conditions during Holocene-Pleistocene.

On the basis of long-term researches of soils in the territory of Russia and Mongolia soil and ecological division into districts of the Baikal region is carried out. At division into districts the whole set of an environment of soil formation was considered. On the map of soil and ecological division into districts 13 mountain, mid-mountain, low-mountain taiga, foothill, hollow-valley, forest-steppe and steppe provinces reflecting surface device originality as the ratio of balance of heat and moisture forming a basis to zoning is shown against the background of difficult orography are allocated. In total 42 districts on lithologic-geomorphological features are allocated. In formation of distinctions of a soil cover of these provinces the leading role is played by bioclimatic factors and inside them the lithologic-geomorphological ones. In the view of structural approach of the district they are considered as territories with a certain natural change of several types of the soil cover structure caused by features of a relief and the parent rock. The map is made in the MapInfo program. It is revealed that on ill-defined width zoning of soils the vertical one which has a greater influence on soils of this region is imposed. Soils of the Baikal region are not similar to the soils located at the same latitude of the flat European territory of Russia. Zone soils of this territory are specific and original.

Early Pottery

A case study of the Neolithic comb ceramic site Pezmog 4 of the Kama culture presents a situation when results of radiocarbon dating change long-existing concepts concerning the development of archaeological events. Until the early 2000s, the chronology of the Kama culture, distributed mainly in the Kama and Vychegda River basins, has been based on comparative-typological analysis. Estimates of the age of this culture changed from the 3rd millennium BC in the 1950s to the 1st half of the 4th millennium BC by the 1990s. Research concerning the Pezmog 4 site in the central Vychegda River basin in 1999–2002 has abruptly changed this chronological understanding. The data obtained put the age of the early stage of Kama culture within the time range 5750–5620 cal BC and allowed us to propose the existence of another way of early pottery distribution in the forest zone of eastern Europe at the beginning of the 6th millennium BC. This innovation probably penetrated from the trans-Ural region.
