The results of the field experiment have been analyzed, it was set up on two experimental fields (with an area of 2.4 hectares each), where two different agricultural techniques – traditional and no-till – were applied. Diagnostics of morphometric parameters of typical chernozems such as: the thickness of the A1 horizon, A1 + AB horizons and the depth of carbonates reaction with 10% HCl, has shown that some changes in soils and soil cover had occurred in the fields over 8 years. The integral indicator of soil productivity is the thickness of the humus horizon, it demonstrated trends to decrease and increase in the soil cover structure of the experimental fields with different compositions of chernozem subtypes. The trends result from both climate change and periodic dry periods, which are not typical of the region, and from the change of traditional technology to no-till. The carbonates leaching from chernozem profiles in all variants of the experiment decreased, which correlates well with climatic indicators, changing with the seasons of the year. Chernozems with thin humus layaer and reacting with HCl close to the surface do not require liming. The revealed changes are not statistically significant, they reflect the resistance of chernozems to the variability of natural and anthropogenic factors of soil formation. Crop residues on the soil surface under no-tillage reduce physical evaporation, which contributes to moisture accumulation in the soil. The use of cover crops in winter also increases the moisture reserves, which are consumed by the plants during the summer growing season. Information on the transformation of morphometric parameters allows making temporal and spatial corrections in the applied agricultural practices (crop rotation, fertilization, the use of cover crops, herbicides and pesticides).

Elementary soil particles are the first soil-specific level in the soil structure hierarchy, which is also the object of the soil texture analysis. To disperse soil solids to elementary soil particles (ESP), it is necessary to break the strong bonds between particles by physical action. An effective way of physical dispersion is to treat soil suspensions with ultrasound. However, depending on the type of soil, the required energy level varies, as it is determined by the stability of the soil structure. In this work the experiment with increasing energy (from 65 to 1 101 J·mL-1) of ultrasonic dispersion at constant power equal to 32.4 W is described. Soil samples from the upper horizons of three types of loamy soils (Retisol, Phaeozem, Chernozem) were used in the experiment. For this purpose, a horn-type ultrasonic disruptor Digital Sonifier S-250D (Branson Ultrasonics, USA) with a stepped solid horn tip (13 mm) was used. It was found that the value of the total energy of dispersion Et required for complete destruction of soil aggregates to ESP depends on soil type and varies within 200–800 J·mL-1 for loamy soils with an organic matter content of 1.8–4.6 g. 100 g-1 soil. For sample preparation of soils for grain-size analysis with a subsequent determination of soil texture class according to Kachinsky classification, the value Et = 250 J·mL-1 is sufficient, as it allows obtaining the maximum amount of physical clay (<10 µm) at the minimum duration of sample preparation.

The paper presents the results of a study of the soil cover of the Shcherbakovsky Nature Park in the Kamyshinsky district of the Volgograd region. To achieve the results 12 soil sections were laid along the studied soil catena (1.5 km), so that morphological and chemical features of the soils of the study area were investigated. Variety and diversity are due to vertical zonality and geological and hydrological peculiarities. So, in the gullies and in massive forest plantations various dark humus and gley soils have become widespread. On steppe, slope and watershed areas lithosolic light humus luvisols and light humus lithozems were formed. On areas with open sand surface, humus psammozems with protohumus horizons W, as well as light humus (AJ-C) and humus soils (A-C), and a variety of soil-forming rocks of the natural park were found. In relief depressions they are represented mainly by gleyed sandy, as well as proluvial-deluvial deposits with inclusions of large fragments of opokas. On steppe and steep-slope areas, the soil-forming rocks are thick layers of opoka deposits. Their upper boundary varies from 20 to 60 cm depth depending on the meso- and microrelief. On the watersheds, the soilforming rocks are represented by sandy, ferruginous deposits with new formations of clay and pseudofibres. The parent rock is registered starting from 100 cm depth and consists of large blocks of hardened sandstone. The chemical properties of the studied soils are characterized by a neutral or slightly acidic pH. Easily soluble salts are leached from all soil horizons. The maximum values of Сorg are typical of humus and transitional horizons. The studies conducted in the Shcherbakovsky Nature Park are of greatest importance for monitoring the state of soils, and also allowed us to identify the features of the genesis of underdeveloped soils and luvisols of the dry-steppe natural zone.

Chicken manure and composts derived from it are valuable organic fertilizers that have a positive impact on soil fertility and significantly enhance crop yields. However, the application of fresh manure can lead to excessive concentrations of nitrogen and other nutrients in the soil, as well as contamination of the soil with microorganisms that are pathogenic to humans and animals. Therefore, it is recommended to compost chicken manure prior to its use in agriculture. This review examines the composition and properties of chicken manure, the techniques involved in its composting, and its influence on the physical, chemical, and biological properties of the soil. The utilization of composted manure results in increased levels of organic carbon (on average by 1–1.5%), nitrogen (by 0.1–0.2%), and other biophilic elements. Moreover, it improves various physical properties of the soil, such as porosity, aeration, and density. Levels of pH increase (by 0.2–0.4), as well as electrical conductivity (by 2–2.5 times), and the quantity of water-resistant aggregates (by 5–10%). The application of these fertilizers also promotes biological activity, microbial diversity, microbial biomass carbon (by 25–75%), and soil enzymatic activity (phosphatase and catalase increase by 5–7 times, and urease by 3–5 times). When chicken manure is incorporated into the soil, a significant (2–4 times) increase in the population of bacteria from the phyla Firmicutes, Bacteroidetes, and Actinobacteria is observed. The necessity of investigating the effects of compost derived from chicken manure on the chemical composition and storage of soil organic matter, pore space, and the ecotrophic structure of the soil microbiome is also discussed.

It is known that one and the same corn plant material can be used to produce silage, cornage, milled grain, or grain for fodder. Each of them contains completely different amounts of nutrients and a wide range of gross yield of fodder units. The results of the research show the direct dependence of the choice of corn use on zonal features of the soil cover and the existing level of chemicalization of agricultural formations of the Republic of Tatarstan, which are considered in detail in this paper. Thus, in order to produce the ploughed grain or corn with the gross harvest of fodder units 7.94–8.82 t/ha and profitability of 78.7% on leached chernozems, which account for 38% of soils of the Republic of Tatarstan, it is recommended to cultivate corn using the complex application of agromeliorants and calculated norms of mineral fertilizers. Liming of acidic dark gray and gray forest soils with phosphorite and zeolite application in combination with NPK provides increase in gross harvest of fodder units of corn silage from 4.22 to 6.13 and 3.34 to 5.86 t/ha respectively. The high efficiency of agrochemicals application on corn crops and forage harvesting of different types of fodder taking into account zonal features of soil cover of the Republic of Tatarstan is also confirmed by economic indicators. The profitability of production of rolled grain reaches the maximum value (78.8%) in the variant with liming and phosphating of leached chernozem combined with the application of mineral fertilizers in rates calculated for obtaining the planned 35 t/ha of green mass. At the same time, on dark gray and gray forest soils as the yield of green mass increases under the influence of agromeliorants the total costs of silage production increases by 13.1 and 16.5 thousand rubles/ha compared with the control variants of the experiment (without agrochemicals). However, the costs of production of 1 000 fodder units are reduced to 9.9 and 10.4 thousand rubles respectively, provided that the sale price is about14 thousand rubles.

The paper presents theoretical basis of the methods for determining the content of soil organic carbon (SOC) both by direct dry combustion using automated analyzers and indirectly – by I.V. Tyurin and Walkley–Black oxidation. Author's and literature experimental data of SOC analyses in various soils by these methods are presented. Comparative analysis of the above data showed that in some cases the content of SOC determined by oxidability is lower than the one obtained by dry combustion (in most cases), while in others, on the contrary, the content of SOC is higher. This conclusion fully complies with the theoretical views of I.V. Tyurin on the chemical nature of soil organic matter (SOM). A schematic description of determining the content of total (organic) carbon in non-carbonate soils by dry combustion method using automated analyzers Leco (USA) and AH-7529 (Gomel, Belarus) is given. It was pointed out that it is difficult to determine SOC content by dry combustion method with automated analyzers in carbonate soils. For these soils it is recommended to determine the content of inorganic carbon by decomposition of carbonates with HClO4 solution using express analyzer AN-7529. The direct method of determining the content of SOC has the best metrological characteristics compared to ones of the indirect method, which convincingly confirms the authoritative opinions of Schollenberg and Tyurin about the inaccuracy of the latter. It is concluded that the indicators determined by the methods of Tyurin and Walkley–Black and dry combustion are chemically independent, characterizing, respectively, the oxidability and organic carbon content of SOM. It is recommended to use dry combustion method with automated analyzers when monitoring the content and stocks of organic carbon in soils.

Soils of archaeological sites are highly interesting objects for multidisciplinary research in various fields of soil science, ecology, archaeology, anthropology and other sciences. Currently, the soils of archaeological sites in the Arctic regions have not been studied sufficiently, although many ancient monuments beyond the polar circle have been found. This work is devoted to the study of morphological and chemical properties of soils of the archaeological site “Settlement Labytnangi 1”, which is located beyond the northern polar circle, near the cities of Labytnangi and Salekhard (Yamal-Nenets Autonomous Okrug). Development of these territories (according to archaeological research) began in the Eneolithic (Late IV – III millennia BC) and continues to the present day. Soil types on the territory of the monument are represented by soil-like bodies (urbikvazizems), podzols, turbozems, urbo-agrozems and peat soils with inclusions of archaeological and anthropogenic artifacts dating back to the XX century. Most of the studied soils were previously subjected to the processes of cryoturbation, although at present the lower boundary of the active layer of permafrost lies at a depth of 120–130 cm, according to the conducted electrophysical sounding. Significant changes occurred in the acid-base properties of the studied soils. In addition, anthropogenic activity entailed the introduction of biophilic elements and organic matter into the soil profile, in particular phosphorus, which is concentrated in the urbanized soil horizons (phosphorus concentrations above 2 800 mg/kg were recorded). The concentrations of heavy metals in the soils are at/below the conventional background (vicinity of Salekhard and Labytnangi). However, some excess concentrations of copper (up to 87.5 mg/kg), zinc (up to 303.3 mg/kg), lead (up to 76.1 mg/kg), and cadmium (up to 2.1 mg/kg) in the urbanized soil horizons have been detected. According to the results of the work, we can conclude that the soils of the archaeological site were formed under the strong influence of modern and past anthropogenic activity, which determined their morphological structure and chemical characteristics at present.

In addition, anthropogenic activity entailed the introduction of biophilic elements and organic matter into the soil profile, in particular phosphorus, which is concentrated in the urbanized soil horizons (phosphorus concentrations above 2 800 mg/kg were recorded). The concentrations of heavy metals in the soils are at/below the conventional background (vicinity of Salekhard and Labytnangi). However, some excess concentrations of copper (up to 87.5 mg/kg), zinc (up to 303.3 mg/kg), lead (up to 76.1 mg/kg), and cadmium (up to 2.1 mg/kg) in the urbanized soil horizons have been detected. According to the results of the work, we can conclude that the soils of the archaeological site were formed under the strong influence of modern and past anthropogenic activity, which determined their morphological structure and chemical characteristics at present.","PeriodicalId":52755,"journal":{"name":"Biulleten'' Pochvennogo instituta im VV Dokuchaeva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46404656","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 article presents the developed soil maps and maps of spatial variability of soil properties (pH, total salt and carbonate content, organic carbon, density) in some recreational areas of Volgograd. The anthropogenic soils in the studied recreational areas include various urbostratozems (Urbic Technosols (Transportic)), Ekranic Technosols (Transportic), as well as quasizems (Phaeozems (Tehnic)), among the agrogenic ones – accumulation-carbonate agrozems (Cambisols (Aric, Protocalcic). Natural soils are represented by light and dark humus soils, chestnut soils, solonetz, as well as stratozems and psammozems. According to the data of isolinear mapping, it was found that acid-alkaline properties of soils of green zones vary from slightly alkaline to alkaline depending on the soil horizon and anthropogenic load. The mapping did not reveal salinization of the upper 0–30 cm layer. Values of organic carbon vary greatly (1–10%) and are conditioned by the presence or absence of meliorative artificial layers, as well as by the character of territory use. The content of calcium carbonates in the upper 30 cm is small and varies from 0.7 to 5%. It is established that the physical properties (density) directly depend on the level of anthropogenic load, increasing in footpaths and lawns. Spatial assessment of the properties of urban soils is important for identifying areas with an excess or on the contrary – low content of certain chemical and physical indicators for the planning of landscaping and gardening of urban areas.

Konstantin Dmitrievich Glinka made a major contribution to the development of such areas of soil science as genesis, geography, cartography and mineralogy of soils. He made the first world soil maps (1908, 1915, 1927), the first soil map of the Asian part of Russia (1927, jointly with L.I. Prasolov), classic studies of weathering processes and transformation of primary minerals into secondary, first studies of buried and relic soils, which laid the foundation for paleosoil science. Fundamental, encyclopedic textbook, written by K.D. Glinka “Soil science” went through six editions (1908–1936) and became a basic guide for many generations of soil scientists. The ideas of K.D. Glinka in the genesis of different types of soils, including gray forest soils, podzols, red earths, burozems (brown soils) have not lost their scientific value until the present day. His outstanding scientific, organizational and pedagogical contribution to the development of genetic soil science has earned K.D. Glinka a well-deserved fame as a scientist of world class.

At the end of the 20th century, a geoinformation database on soil degradation in Russia, relied on the soil map of Russia at a scale of 1 : 5 million, was developed under the leadership of V.S. Stolbovoy. As part of the development of this problem and in the course of obtaining new information on soil degradation, an attempt was made to refine and supplement this database, that relies on the soil map of the Russian Federation 1 : 2.5 million scale. Soil degradation resulted from the impact of various types of pollution was taken into account, including industrial emissions, leakage of oil products, excessive application of pesticides, the impact of vehicles and radiation pollution. Each soil polygon of the soil map exposed to the pollution was characterized by the degree and area of pollution in accordance with the developed scales. The results of the analysis were used to construct cartograms illustrating the spatial distribution of chemical and radiation degradation of the country soils. According to the data obtained, in the zone of pollution derived from industrial enterprises and oil pollution, 20% of the soil-geographic polygons of the map are characterized by a strong degree of pollution, and 30% and 50% – by weak and medium, respectively. Agricultural pollution due to excessive use of plant protection products in Russia does not exceed 10% of the area of polygons and is characterized by a low degree. About 10% of the soil polygons of the basic soil map are heavily contaminated with radioactive contamination, while 40% and 50% of the polygons are moderately and weakly contaminated, respectively. Pollution from vehicles is weak and generally has low level. At the same time, megacities and highways with heavy traffic are distinguished by relatively high level of pollution.
