Subject:
accidents; algorithms; cesium; nuclear power; power plants; radionuclides; simulation models; soil; strontium
Abstract:
... The possibility of using the VERT_MIG algorithm in simulation models of the vertical migration of radionuclides in soil is discussed. The algorithm was successfully used to develop models of ¹³⁷Cs and ⁹⁰Sr migration for radioactive contamination of different soils as a result of the accidents at the Chernobyl and Fukushima-1 nuclear power plants. The modeling results are given. Prospects for furth ...

Subject:
Albeluvisols; Luvisols; Phaeozems; Podzols; algorithms; deciduous forests; gray forest soils; mountains; parent rock; soil profiles; taiga; zoning; Caucasus region; Russia
Abstract:
... The paper describes approaches assessing the diversity of soils in Russia, as well as algorithms for quantitatively assessing the differentiation of soil bodies and covers. To assess soil diversity (or the degree of differentiation of parent rock materials into soil bodies and soil covers), two indices have been introduced: the vertical differentiation index (Ird) and the spatial lateral different ...

Abstract:
... The features of cesium-137 (¹³⁷Cs) root uptake by spring oat (Avena sativa L.) and lettuce (Lactuca sativa L.) plants have been studied in a model experiment with simulation of radionuclide fallout into undisturbed monoliths of arable chernozems from the Plavsk radioactive spot. An integrated approach using digital autoradiography and γ-spectrometry methods has revealed a uniform pattern of vertic ...

4. Diagnostics of Compaction of Arable Soils in the Transvolga Region in Saratov Oblast

Author:
Sorokin, A.S.; Kust, G.S.

Subject:
Chernozems; alkalinity; arable soils; clay; clay fraction; diagnostic techniques; exchangeable sodium; pH; plows; porosity
Abstract:
... The evidence and factors of the formation of compact horizons in haplic chernozems are discussed. They include a complicated combination of agronomical consolidation, modern solonetzization, and residual alkalinity. It is shown that the combination of physicomechanical and chemical properties (high content of physical clay and clay fraction, low portion of aggregate openness and high interaggregat ...

Abstract:
... The effect of amorphous silicon dioxide (SiO₂) on cadmium behavior in the soil–plant system was studied in a field experiment on a flooded paddy soil slightly contaminated by cadmium. The application of amorphous SiO₂ results in a 1.3- to 1.8-fold smaller cadmium accumulation in the aboveground organs of rice and a 1.8- to 2.6-fold decrease in the content of its available compounds, which can be e ...

Abstract:
... In the discontinuous cryolithozone in the north of Western Siberia in forest and tundra biogeocoenoses, two field methods for individual determination of root and microbial soil respiration were tested: plant shading and root exclusion (comparison of the plots with vegetation and without it). The proportion of of root respiration in the total soil respiration in the forest biogeocoenosis was 7–50% ...

Abstract:
... For the first time, a theoretical equation is derived for the concentration of microelements entering the soil with atmospheric precipitation as a function of depth and time; it was tested with data on the longterm dynamics of certain metals (copper, nickel, and manganese) in the soils of Moscow State University lysimeters under different types of plantations. ...
