Research ArticleOpen accessIn the author namesCurrent State of Haplic Chernozems in Specially Protected Natural Areas of the Steppe ZoneSaglara S. Mandzhieva, Lyudmila Yu. Goncharova, Abdulmalik A. Batukaev et al.The current ecological state of Haplic Chernozems has been studied in three Specially Protected Natural Areas (SPNAs) of the Steppe zone in South of Russia. It has been found that the content of organic matter, texture and elements content of soils depend on the period and conditions of reservation in the SPNA. In accordance with the content and reserve of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 13 Dec 2017 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Heavy Metals on the Enzymatic Activity of Haplic Chernozem under Model Experimental ConditionsNatalia Gromakova, Saglara Mandzhieva, Tatiana Minkina et al.The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Jul 2017 · 7,994 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and Oil Contamination by Biological IndicatorsSergey Ilyich Kolesnikov, Natalya Aleksandrovna Petrova, Kamil Shagidullovich Kazeev et al.Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 5 Aug 2016 · 7,883 accessesView PDFCite
Research ArticleOpen accessIn the author namesThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the author namesModels of Winter Wheat Yield Based on Calcareous Chernozem Fertility ParametersOlga A. Biryukova, Dmitry V. Bozhkov, Tatiana M. Minkina et al.The use of polyelement diagnostics and regression analysis for predicting the yield of winter wheat at different stages of vegetation is considered. It has been established that the prediction and integrated assessment of grain yield and quality should be performed with consideration for the balance of macro-and micronutrients in the grain and the aboveground biomass of plants. Possibility of predicting … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 1 Jan 2016 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the author namesSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,586 accessesView PDFCite
Review ArticleOpen accessIn the author namesAnalysis of Benzo[a]Pyrene Contamination from an Long-Term Contaminated SoilSvetlana Sushkova, Tatiana Minkina, Abdulmalik Batukaev et al.Analysis of benzo[a]pyrene contamination from an aged contaminated chernozemic, meadow-chernozemic and alluvial soils under the effect of aerotechnogenic emissions from the Novocherkassk regional power plant have been revealed on the basis of annual monitoring studies from 2008 to 2012. A new ecologically clean highly-effective express-method of subcritical water extraction has been developed for determination of benzo[a]pyrene from soils of the … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 16 Nov 2015 · 7,868 accessesView PDFCite
Research ArticleOpen accessIn the author namesDesorption of Exchangeable Cations at Adsorption of Lead Ions by Chernozem in the Presence of Attendant AnionsT. M. Minkina, D. L. Pinskii, S. S. Mandzhieva et al.The effect of Cl–, Ac‾ and NO3‾ anions on the adsorption of Pb cations by an ordinary chernozem and desorption of exchangeable cations in the soil-solution system has been assessed under model laboratory conditions. It has been shown that the attendant anions affect the shape of the adsorption isotherms, which are described by the Langmuir equation. The greatest influence on … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 20 Oct 2015 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the author namesFeatures of Microelement Composition of Ordinary Chernozems of the Azov and Lower Don RegionsTatiana M. Minkina, Nikolay N. Miroshnichenko, Aleksandr I. Fateev et al.Ordinary chernozems in the Azov Plain have a low background content of mobile zinc compounds, a sufficient supply with copper and an increased content of lead compounds. This specificity of the regional microelement composition is due to the high carbonate content in the soil profiles, the natural enrichment of littoral geochemical landscapes and the effect of the significant sources of … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 3 · 27 Jul 2015 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the author namesACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,450 accessesView PDFCite
