The assessment of the possibility of creating a plant-soil cover on an artificially created seal-gravel drainage layer with a rocky bed (h=110¸150 cm), on the disturbed areas of the adjacent areas of tailings storage facilities. Research for 2017–2019 shows that when sowing recult-vants with sowing standards of 150–200 kg/ha and doses of fertilizer N60P60K60 and N120P60K60 on an artificial substrate it is possible to form meadow formations with a density of grass 10–12000 pc/m2 and average productivity of 21–24 c/ha. A plant-soil-blooded blood with a turf layer of 8–10 cm is created with the simultaneous overlap of heavy metals of man-made substrates and elimination of pulp sands dusting, which contributes to the improvement of the microclimate of the environment.

Abstract Aims Consequences of climate change and land use intensification on the nitrogen (N) cycle of organic-matter rich grassland soils in the alpine region remain poorly understood. We aimed to identify fates of fertilizer N and to determine the overall N balance of an organic-matter rich grassland in the European alpine region as influenced by intensified management and warming. Methods We combined 15N cattle slurry labelling with a space for time climate change experiment, which was based on translocation of intact plant-soil mesocosms down an elevational gradient to induce warming of +1 °C and + 3 °C. Mesocosms were subject to either extensive or intensive management. The fate of slurry-N was traced in the plant-soil system. Results Grassland productivity was very high (8.2 t - 19.4 t dm ha−1 yr−1), recovery of slurry 15N in mowed plant biomass was, however, low (9.6–14.7%), illustrating low fertilizer N use efficiency and high supply of plant available N via mineralization of soil organic matter (SOM). Higher 15N recovery rates (20.2–31.8%) were found in the soil N pool, dominated by recovery in unextractable N. Total 15N recovery was approximately half of the applied tracer, indicating substantial loss to the environment. Overall, high N export by harvest (107–360 kg N ha−1 yr−1) markedly exceeded N inputs, leading to a negative grassland N balance. Conclusions Here provided results suggests a risk of soil N mining in montane grasslands, which increases both under climate change and land use intensification.

It is shown that the chemical composition of the litter falls and wood of deciduous and coniferous trees is different. On the background of aerotechnogenic pollution, accumulation of individual heavy metals, an increase in ash content was noted. There was revealed the anthropogenic dynamics of the accumulation of heavy metals in the wood of trees: the maximum number during the period of diesel traction; as the railway site is electrified, the accumulation of elements decreases. The obtained data can be recommended to be used for phytoremediation at sites subject to pollution. The obtained data will be the basis for assessing the phytoextractive potential of woody plants, in diagnosing aero-technogenic pollution of the environment, solving the problem of reducing environmental risks, as well as during the modernization and planning of environmental measures in the field of railway infrastructure.

This paper is dedicated to an integrated environmental assessment of soil cover in the Ivanovo Region’s territory. Using modern instrumental methods of analytical control has been determined a content of gross and mobile forms for Pb, Cd, Co, Ni, Zn, Mn, Cu and Fe in the soil. The analysis of the soils ecological state in the period from 2010 to 2014 has been performed. It has been found that the region soils are generally characterized by relatively low levels of heavy metals contamination. Areas with high concentrations of heavy metals’ mainly mobile forms are local ones. For the first time in Ivanovo region has been performed an assessment related to potential risk of soil contamination for the public health. Comparison of experimental results with statistical materials on morbidity and mortality, as well as the subsequent analysis of the obtained data together with the results of sanitary-hygienic research allow highlight the most contaminated areas, and identify potential sources of negative impacts, as well as to conduct ecological and hygienic assessment for investigated region’s soil status. Using of vivid cartographical techniques allows visually assess the scale of contamination for Ivanovo region’s soil cover, and reveal this information to the public in a timely manner.

The management and protection of soil cover: an ecosystem approach There is need for increased societal awareness of the importance of soil management for varying specific uses and for protection of the environment. The main purpose of the study was to analyze the role of soils in the formation and function of ecosystems, to elucidate the properties and mechanisms which play the main role in plant-soil mutual relationships, and to generalize the pedoecological principles of soil management and protection in conditions of Estonia. The treatment is a departure from the pedocentric viewpoint and is based on an ecosystem approach. The relationships between soil and plant covers are tested quantitatively on the basis of the ecosystems' phytoproductivity and fluxes of organic carbon, and qualitatively on the ground of humus forms and site types. On the basis of personal research and data available in literature, the constraints limiting soil cover functioning, the soil degradation features which occurred in actual time and the measures and activities for prevention of soil degradation are analyzed. Problems connected with biodiversity and soil environment protection ability as they relate to soil cover management and protection are discussed. For sustainable land use and to avoid deterioration of soil properties, the experience of local farmers, scientific research and monitoring of degradation features are needed. The soil cover is protected (or sustainable land use is attained) in circumstances when soil fertility and functioning is maintained adequately for the soil types' characteristics. Soil cover should be considered as a medium through which it is possible to improve the environmental status of the area.

The growth of production zones in the city of Aksai in the West Kazakhstan region leads to contamination of the soil cover, which, in turn, causes a chain reaction of pollution. Due to soil contamination, soil moisture and the underground surface are polluted. As a result, the processes in the soil change, the vital activity of plants, animals and microorganisms are disrupted. The article presents data on the study of changes in soil cover under the influence of human activity. The results of the conducted studies on the determination of the humus content and pH level, the content of heavy metals in technogenically disturbed soils in the adjacent territory of the natural gas processing enterprise are presented. The obtained data on the gross content and mobile forms of heavy metals indicates that the maximum permissible concentration level for these pollutants is not exceeded.

Heavy metals and other trace elements that are not subject to degradation are among the priority pollutants. Significant amounts of heavy metals and related elements with variable valence are deposited on the soil surface as part of aerosols. Accumulating in the soil, they are very slowly removed from it, only changing the level of content or the state during migration, turning the soil over time into a source of secondary pollution. In this regard, an extremely urgent task is to assess the territory, especially such a highly developed and densely populated area as the Moscow Region, in terms of its protective potential to heavy metal pollution. The paper proposes and tested an algorithm for the cartographic assessment of the protective potential of the soil and vegetation cover of the region using GIS analysis methods based on the database “Digital medium-scale soil map of the Moscow region” and a vector map of forest cover. The formula used for calculations includes data on the soil texture, the content of organic matter in soil, the position of the soil in the landscape and the degree of forest cover of the territory. According to the proposed approach, in the Moscow region, the soil cover, taking into account the forest cover, forms 4 groups according to the level of protective potential for contamination with heavy metals and metalloids. The maximum estimate was obtained for noneroded sod-podzolic soils of medium or fine texture, gray forest soils, chernozems and peat bog soils under forest vegetation (17 % of the area). Unerroded soddy-podzolic soils of varying degrees of podzolization and gleying (45 %) received an average rating. Even lower is the protective potential of 22 % of the territory represented by eroded gray forest soils, various sod-podzolic, alluvial and peat bog soils. This group is the most heterogeneous in terms of soil texture, organic matter content and degree of forest cover. The group with a minimum protective potential included eroded soils, soils of gully-girder complexes, sod-podzolic soils of coarst texture, as well as alluvial peat and peaty soils (about 16 %).
