Pages: 139-142

Abstract >>
Historical progress of development and improvement of soil research in West Siberia is considered. The contribution made by the first Siberian researchers in soil science, followers of V. V. Dokuchaev's ideas, is considered. A large amount of work made by expeditions of the Migration Administration and the Commission on Exploration of Natural Productive Forces at the Academy of Sciences is stressed. Special attention is paid to the modern status of the investigations of Siberian soil and the position of the Institute of Soil Science and Agricultural Chemistry SB RAS in these investigations.

Ecology of Soils: Formation of a New Science of the Biosphere Class

M. I. Dergacheva
Keywords: ecology of soils, biosphere, methods, humus
Pages: 143-150

Abstract >>
History of formation and the set of methods of the new science, namely ecology of soils, are discussed. The object, subject, positions in the system of sciences and the most urgent problems are defined. The necessity to relate the ecology of soil to the sciences of the biosphere class is justified. Examples illustrating some statements, regularities and laws of the ecology of soil are described. It is shown that different components of soil humus and their ratios have specific connections with the characteristics of climate and fall within quite definite ecological ranges of the existence of soil kinds with different ratios of humic acids.

Black Soil of the Novosibirsk Region, Problems of their Rational Use and Conservation

V. A. Khmelev, A. A. Tanasienko
Keywords: formation of black soil, black soil, profile, regime, horizon, humus, resource, erosion, deflation, conservation
Pages: 151-164

Abstract >>
On the basis of the generalization of literature and our own data characterizing the virgin and ploughed black soil of the Pre-Altay forest-steppe and West Siberian soil provinces, it is concluded that these kinds of black soil comprise the gold fund of the soil of the Novosibirsk Region (NSR): they served and still serve as a reliable basis of the agricultural production in the most highly developed region of West Siberia. However, the black soil of NSR are exposed to increasing erosion destruction. These phenomena, being negative for land tenure, become most strongly pronounced in the regions where the most valuable kinds of black soil - leached and podzolized - are spread. Because of this, soil conservation and natural economic measures are attaining increasingly high importance.

Thermodynamic Indices of Active Invertase from Buried Soil Horizons of the Later Pleistocene Age in the North of Yakutia

M. V. Shchelchkova
Keywords: permafrost sediments, later Pleistocene, enzymatic activity of soil, invertase, thermodynamic characteristics, temperature coefficient, activation energy, immobilization
Pages: 195-201

Abstract >>
New data on the enzymatic activity of the tundra peaty gleyey soil and permafrost sediments on the Later Pleistocene age (11-25 thousand years ago) are analyzed. It is shown that invertase, protease, phosphatase, catalase, peroxidase are well conserved in yedoma and in buried soil horizons; urease is conserved to a smaller extent. On the basis of the investigation of thermodynamic characteristics of active invertase, such as temperature coefficient and activation energy, it was established that this enzyme is present in soil in the free state and in the bound form (immobilized on the surface of organic-mineral colloids). The degree of immobilization of active invertase in the buries soil horizons is high, which is likely to play an important part in the conservation of its molecules at negative temperatures for a long time.

Divergence of the Probabilistic Distributions of Soil Properties as a Quantitative Characteristic of the Transformation of Soil Cover

I. V. Mikheeva
Keywords: soil properties, variability, probabilistic distributions, dynаmics, divergence
Pages: 231-236

Abstract >>
Divergence value, calculated as the quantitative index of the closeness of probabilistic distributions of soil properties, is used to estimate the degree of differences of soil kinds in connection with the inhomogeneity of soil formation factors, as well with natural and anthropogenic processes. We report the results of the calculations of divergence of humus content in the soils of the dry steppe zone of the south of West Siberia, caused by the difference in granulometric composition, deflation and agricultural use. This allows us to reveal the most vulnerable varieties and to range natural and anthropogenic effects according to the value of their influence on soil properties.

Stability of Grass Ecosystems

A. A. Titlyanova
Keywords: ecosystem, biological turnover, phytocenosis production, phytomass
Pages: 237-243

Abstract >>
Two aspects of the stability of grass ecosystems are considered theoretically and with specific examples: the ability to maintain the structures and functions, and the ability to recover them after disturbances. The low resistance of the species structure of the grass community and the high stability of the biotic turnover, both its structure and functioning, were demonstrated. In spite of the low resistance, the species structure of the phytocenosis possesses high elasticity, which is expressed in its recovery within a short time interval in the presence of seeds and after removal of the stressing action.

A. I. Syso, A. M. Peregon
Keywords: Holocene, climate change, bog formation, peat biogeochemistry, Bolshoye Vasyuganskoye bog
Pages: 245-250

Abstract >>
Development of bog formation processes at the southern boundary of the taiga zone in West Siberia is analyzed depending on the cyclic changes of climate, which is depicted in the botanical and chemical composition of peat. It is shown that modern climate warming did not interrupt bog formation which occurs here due to forest underflooding with water of bog massifs and periodic underflooding of floodplain depressions during the cycles in wet years.

One of the grass bongs is situated in Russia, other two bogs are in Poland. The comparison showed that the common climatic and geochemical features of the position affect the chemical nature of the phytomass. Grass bogs are richer in nitrogen that sphagnum ones; both Polish bogs have an increased K and decreased

About Fluorine Content in Natural Water in the Southern Part of the Territory Between the Ob and the Irtysh

Y. V. Ermolov
Keywords: fluorine, natural water, territory between the Ob and the Irtysh, ecological-geochemical evaluation
Pages: 319-325

Abstract >>
Fluorine content in 327 sources of surface, soil-ground and underground water in the south of the territory between the Ob and the Irtysh is investigated. Substantial variations of fluorine concentration in water are revealed; its possible geochemical reasons are considered. A large region with high (> MPC) fluorine concentration in the sources of underground water involved in water supply to settlements was discovered in the western part of the Baraba plain. The values of fluorine to calcium ratios in those water samples provide evidence of the high danger of fluorosis in the population.
