AbstractThe changes in the physical properties and carbon stocks of dark-humus podbels (Luvic Albic Mollic Planosols (Epiloamic, Endoclayic, Aric)) during long-term agricultural use and postagrogenic evolution were studied. Soil samples were taken in three trials: control (without fertilizers), high rates of mineral fertilizers, and mineral fertili...

AbstractWe have compared the impact of heavy metals (HMs: Cu 660 + Zn 1100 + Pb 650 mg/kg) on agrosoddy-podzolic soils (Albic Retisols (Loamic, Aric, Cutanic, Ochric)) of two arable fields (Chashnikovo, Moscow oblast) with different contents of organic carbon (Corg 3.86 and 1.30%) and different fertility levels using indicators of acute and chronic...

AbstractThe aim of this study is to model the water-retention capacity and the relative hydraulic conductivity of the soil as a capillary-porous medium, as well as to verify the proposed models in comparison with the well-known world analogues. This aim is achieved by solving the following tasks: (1) description of the soil hydrophysical properties...

AbstractData on the spatial distribution of calcium carbonates (CaCO3) in the surface layer and in the profiles of irrigated soils at two key plots of the Svetloyarsk irrigation system in Volgograd oblast are presented. The key plots are located in different natural areas of the dry-steppe zone: the Yergeni Upland and the Caspian Lowland. The field...

AbstractNatural 13C abundance and chemical structure of different organic matter (OM) pools of Haplic Chernozem in contrasting land use variants (steppe and long-term bare fallow) are described. The sequence of OM decomposition in soils is traced. The pattern of changes in OM chemical structure of virgin chernozems under steppe from free (LFfr) to ...

AbstractThe contents of 19 priority polycyclic aromatic hydrocarbons (PAHs) have been studied in soils (Spolic Technosols) and parent rocks of dumps at the Gorlovskoe anthracite deposit (Novosibirsk region). The bulk content of polyarenes in the analyzed soils is highly variable: from 100 to 74 622 ng/g. The absence of statistically significant rel...

AbstractThe prokaryotic and fungal biomass was estimated by luminescent microscopy; the number of ribosomal gene copies of microorganisms was determined by the real-time PCR method, and the taxonomic diversity of culturable micromycetes in Albic Podzols was studied along the pollution gradient (1.5, 8, 15, and 50 km) from the Kandalaksha aluminum s...

AbstractIsotopic composition of nitrogen in soil microbial biomass (δ15Nmicr) is connected with the transformation of nitrogen compounds and with the balance of carbon and nitrogen availability for microorganisms. We have studied the dependence of δ15Nmicr on nitrogen isotopic composition in the substrate (δ15N of total and extractable nitrogen), a...

AbstractThe experiments on mobilization of soil organic matter during soil washing with ultrafresh water against the background of salinity pulsing were designed and performed. Unpolluted soil and the soil artificially polluted with copper(II) were used in experiments, namely, clay loamy typical chernozem (Haplic Chernozem) of the Alekhin Central C...

AbstractAt present, the genesis, nomenclature, and classification of granuzems remain debatable, which is explained by scarce data on these soils. In this paper, data on granuzems described in the forest-tundra of the Norilsk depression, in the valleys of the Tukalanda, Akkit, and Khantaika rivers (68°30′ N, 88°15′ E) and in the northern taiga with...
