This article provides the results of actual, potential and exchangeable acidity measurements performed in 87 soil profiles located within the upper and middle reaches of the Amur River. Descriptive statistics, correlation and linear regression were used to characterize acidity. It has been established that acidity decreases in the floodplain of the upper and middle reaches of the Amur River in the following direction: alluvial marsh (peat-gley and humus-gley) soils, residually-alluvial (rzhavozems and brunezems) soils, alluvial gray gley soil, alluvial gray humus. The soils of the upper Amur floodplain are more acidic in comparison with the soils of the middle Amur, the average pH KCl values in soils with the same genesis of the former are less by 0.2–0.4 than the ones of the latter. It was revealed that the regression coefficient is indicative of the acid-base functional groups of the soil components which are in charge of soil pH. The coefficient greater than 1 points to the organic nature of acidity; below 1 – to the prevalence of mineral acids.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41574875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The topsoils of chestnut and brown aridic soils meet the criteria for the light-humus horizon (AJ), but their values in Munsell readings proved to be lower. In pale soils, the upper horizons were identified as gray-humus instead of light-humus ones as prescribed in the system. The cryohumus AK horizon, diagnostic for cryoaridic soils, is peculiar by the abundance of reddish frost-fragmented plant residues (detritus). We failed to differentiate metamorphic BM and xerometamorphic BMK horizon, they had more features of the latter. Both horizons are similar to the pale-metamorphic BPL horizon in color, although the BPL has a definitely weaker structure displaying some cryogenic features. These are less prominent in cryoaridic soils than in pale soils, hence, the diagnostic BPL horizon in cryoaridic soils may be removed to the category of diagnostic property. A similar re-evaluation may be proposed for the carbonate-textural CAT horizon: to consider it as a diagnostic property in the carbonate-accumulative horizon (ВСАt). The ВСА horizon in all soils studied differed by carbonate pedofeatures, namely, segregations in brown and chestnut soils, impregnations in pale soils, impregnations and coatings in cryoaridic soils.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68254165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was characterized by alternating dark and light wide strips visible on the satellite image. The field was irrigated until the mid-1990s and was subject to secondary salinization, since that time it has been used in dry-farming system. The soil combination is performed by steppe light chestnut solonetzic complex that was transformed due to the surface leveling and irrigation into agrozem accumulative-carbonate segregation saline (Sodic Endoprotosalic Cambisol (Loamic, Aric, Protocalcic, Ochric, Bathygypsic) and Cambic Calcisols (Loamic, Aric)) and deep saline, and agro-light-humus accumulative-carbonate stratified soil. The bright bands on the field mark soils rich in carbonates on the surface (12–13 % CaCO 3 ) (Calcaric Cambisol (Loamic, Aric)) among the other soils that contain less carbonates on the surface by 5–10 times. All the soils are saline, but the salt content varies in space in a wave-like manner, wich disagrees with the satellite image. Two-dimensional distributions of carbonates and salts in the soil combination are discussed. The residual signs of secondary salinization are revealed in the form of calcium and magnesium chlorides two decades after the cessation of irrigation and drawdown of the groundwater curve deeper than 7 m.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48547662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples of kaolinite, a standard sample of chernozem and samples of agro-chestnut soil were taken for the experiment. The results of the CA measurements using two types of sample preparation for the analysis were compared. The first method of sample preparation was to apply a sample to a double-sided adhesive tape; the second method involved the deposition of suspensions of the studied samples of certain concentrations on membrane filters. The advantages and disadvantages of each sample preparation method are described. The significant difference in the obtained CA values depending on the sample preparation for measurement was revealed. The method of sample preparation with the use of membrane filters developed by the authors made it possible to reduce the CA measurement error by more than 2 times. Reducing the variation of the CA value of a single sample will allow comparing similar soil samples, including soils of the same type, but involved in different land use systems.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42138015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More than 120 soil samples were collected for subsequent physical and chemical analyses. Ecological, chemical and physical properties of meadow and steppe soils of Ol’khon district were studied and the results are presented in the article. The research was conducted on the east coast of the Lake Baikal in its central basin, which is most visited by tourists. Several soil types can be found along the coast line and on gently sloped surface nearby, they are: castanozems, umbrisols, cambisols, gray soils, histic fluvisols gleyic, humic fluvisols gleyic, chernozems, umbric fluvisols, cambic fluvisols and other. Owing to a specific environmental conditions some original soil types (for example “chestnut soils”, “castanozems”) can be found nowhere else in the Irkutsk region but only here. The explored soil profiles are mainly thick and stony to various extent (from high to medium),these soils are sandy or sandy loams, rich in humus, predominantly with neutral and weakly alkaline reaction (pH), low content of nitrogen in relation to carbon content (C : N), that creates favorable conditions for preservation of the vegetable remains in meadow landscapes. The conducted research results revealed that soils near touristic tracks and also on the territory of the ancient settlement are polluted by heavy metals, and their content exceeds sanitary and hygienic standards. The ecological condition of soils at the present stage can be characterized as average degree of disturbance resulting from recreational activity. Geochemical barriers are represented by organic and alkaline ones. However, due to the sandy and sandy-loamy soil texture waters of the lake coastal zone can be polluted by heavy metals as well. Soils of meadow-boggy landscapes of the coastal area are not polluted by heavy metals as far as it is a hard-to-reach region for tourists using automobile transport.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68253898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In short-term laboratory experiments we studied the possibility of stabilization of heavy metals labile forms by commercial humic substances (HS) of different origin (peat humate “Flexom” and coal humate “Extra”) in comparison with HS, inoculated by microorganisms – nitrogen fixers and mycorrhizae-forming fungi and mineral fertilizers (NPK и CaCO3). Experiments were provided during 45 days after 14 days of pre-incubation under controlled conditions in climate chamber with light, temperature and humidity imitating the polar day conditions in Kola Subarctic. After experiments we evaluated changes in soil chemical properties, soil microbial community and test-culture (Deschampsia cespitosa). Peat humate application is ineffective without additional manipulations (e.g. combination with CaCO3), cooperation with biological applicants cannot be pointed out. Application of coal humate favours to metals stabilization, soil microorganism’s activation, test-culture growth. It may be effective to combine coal humate with biological applicants like mycorrhizae-forming fungi. So, coal-humates may be perspective growth-stimulator, ameliorant and detoxicant in remediation of degraded soils in conditions of polymetallic contamination.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68253554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
