Middle Devonian Acid Sulfate Paleosol: The First Finding in the Central Devonian Field (Voronezh High, Southern Russia)
Eurasian Soil Science - - 2024
T. V. Alekseeva, A. O. Alekseev
The Middle Devonian (Eifelian) paleosol (PS) recently discovered in the area of Voronezh Anteclise has been studied in detail. The PS is developed from acid volcanic rock, rhyolitic tuff. The thickness of laterally continuous PS varies from 20 to 150 cm depending on the relief of the Proterozoic basement beneath it. The tuff contains the inclusions of allochthonous coal particles most part of whic...... hiện toàn bộ
Aerodynamic method for obtaining the soil water retention curve
Eurasian Soil Science - Tập 46 - Trang 751-757 - 2013
V. V. Alekseev, I. I. Maksimov
A new method for the rapid plotting of the soil water retention curve (SWRC) has been proposed that considers the soil water as an environment limited by the soil solid phase on one side and by the soil air on the other side. Both contact surfaces have surface energies, which play the main role in water retention. The use of an idealized soil model with consideration for the nonequilibrium thermod...... hiện toàn bộ
Vis-NIR Spectroscopy for Soil Organic Carbon Assessment: A Meta-Analysis
Eurasian Soil Science - Tập 56 - Trang 1605-1617 - 2023
A. V. Chinilin, G. V. Vindeker, I. Yu. Savin
The research papers assessing the content of soil organic carbon with the help of Vis-NIR spectroscopy approaches are systematically analyzed and subject to meta-analysis. This meta-analysis included 134 studies published in 1986–2022 with a total sample of 709 values of quantitative metrics. The papers have been searched for in databases of scientific periodicals (RSCI, Science Direct, Scopus, an...... hiện toàn bộ
Geochemical Characterization and Evolution of Soils from Krakatau Islands
Eurasian Soil Science - Tập 54 - Trang 1629-1643 - 2021
D. Fiantis, F. I. Ginting, Gusnidar, M. Nelson, E. Van Ranst, B. Minasny
The Krakatau islands complex was formed after the huge eruption of the late Mt. Krakatau in 1883. The complex consists of four islands: Rakata, Panjang, Sertung, and Anak Krakatau. While volcanic activity and plant succession have been extensively studied in the Krakatau area, the soils received less attention. This study characterizes the morphology, chemistry, and geochemistry of the soils from ...... hiện toàn bộ

Effect of the biota diversity on the composition of low-molecular-weight water-soluble organic compounds in southern tundra soils
Eurasian Soil Science - Tập 47 - Trang 173-181 - 2014
E. V. Shamrikova, O. S. Kubik, V. V. Punegov, I. V. Gruzdev
Water extracts from the organic horizons of southern-tundra loamy permafrost-affected soils (a surface-gleyed tundra soil, a surface-gleyed soddy tundra soil (Haplic Stagnosols (Gelic)), and a peaty tundra soil (Histic Cryosol (Reductaquic)) and their undecomposed moss layers have been analyzed. The total weight concentration of the cations (Ca2+, Mg2+, K+, and Na+) determined by the atomic absorp...... hiện toàn bộ
Soil Hydrology of Agricultural Landscapes: Quantitative Description, Research Methods, and Availability of Soil Water
Eurasian Soil Science - - 2021
Ye. V. Shein, A. G. Bolotov, A. V. Dembovetskii
Soil hydrology has deep Russian roots, which are primarily related to the theory of soil hydrological constants and their practical application. These constants have been used to assess the hydrological soil conditions in stationary observations, for which attempts to arrange regular hydrological observations in the landscape faced impracticable complexity of work and calculations and provided unr...... hiện toàn bộ
The state of natural radionuclides of uranium, radium, and thorium in soils
Eurasian Soil Science - Tập 43 - Trang 651-658 - 2010
N. G. Rachkova, I. I. Shuktomova, A. I. Taskaev
A review of publications is presented on the state of uranium, radium, and thorium in soils. It is shown that the properties of radionuclides in soils provide the diversity of the forms and mechanisms of their fixation in the soil exchange complex. Organic substances and clay minerals are the most important sorbents of uranium, radium, and thorium. According to the available data, the processes of...... hiện toàn bộ
Soil Structuring in the Presence of the Chitosan–Polyacrylic Acid Interpolymer Complex
Eurasian Soil Science - Tập 53 - Trang 1773-1781 - 2021
L. K. Orazzhanova, Zh. S. Kassymova, B. Kh. Mussabayeva, A. N. Klivenko
This article presents the results of the study of a new soil structuring agent—the interpolymer complex of a chitosan biopolymer and a synthetic polymer of polyacrylic acid—applied to the surface layer of a light chestnut soil (Kastanozem) in the East Kazakhstan region. The interpolymer complex was obtained by mixing equimolar polymer solutions. The composition of the [chitosan] : [polyacrylic aci...... hiện toàn bộ
