The methodology for biodiagnostics of the ecological state of soils and other environmental objects involves the use of two approaches: bioindicative observations in situand biotesting of samples, carried out according to standard methods in controlled laboratory conditions ex situ. An integrated assessment of soils on an interdisciplinary basis in accordance with the international standard ISO19204-2017 makes it possible to diagnose of soils “health” based on biotic parameters in the course of natural environmental observations, ecotoxicity indicators, which are supple-mented by the results of quantitative chemical analysis (TRIAD methodology). For soils, indicators of the state of higher plants and microbial communities, especially in agroecosystems, are of paramount importance. The article analyzes the advantages and limitations of well-known methods of phytoindication, laboratory phytotesting, soil respiration, structural and functional indicators of microbiota diversity and bacterial biosensors. The responses of living systems to the same pollutant content largely depend on the carbon content of organic matter. The existing regulatory framework for the ecological assessment of the biological state of soil ecosystems practically does not take into account this, as well as the level of mineralization and pH of the analyzed objects. For an adequate assessment of the ecological quality of soils, it is proposed to improve the methods of measuring toxicity by more targeted recommendations for application (for example, for certain gradations of humus content, mineralization, pH).

The article analyses the problems of establishing factual circumstances of environmental violations against soils, presents examples from the judicial practice, shows the possibilities of using special knowledge when considering cases relating to negative anthropological impact on soil-geological objects. The following methods were used in the research: observation, analysis, synthesis, description, comparison. It is substantiated the need for wider application of results of forensic examination of geological evidence in the administration of justice. The most effective and science-based form of using special knowledge is forensic environmental examination and particularly geological evidence examination or forensic environmental and soil expertise. Such kind of examinations are actively carried out in FBE «Russian Federal Centre of Forensic Science of the Ministry of Justice of the Russian Federation» and in FSPI «Forensic Expert Centre of the Investigative Committee of the Russian Federation». It is given an example of a complex forensic environmental examination. Proposals are presented to expand the range of persons conducting forensic environmental and soil examinations.

The research demonstrates the cadastral value calculation sensitivity to agroclimatic parameters and (soil conditions/ factors determing soil fertility) in humid, arid and semiarid territories of the Russian Federation. The regularities to decrease the cadastral value of agrolandscapes are determined with an increase of gleying, (soil) erosion, stonyness, salinization, alkalinization, def ation and over consolidation of soils. Cadastral value of agrolandscapes significantly increases due to drainage and irrigation.

The damage caused by soil and land degradation was assessed at three hierarchical levels (the region as a whole, the municipality, the agricultural sector) of the spatial organization of six test regions of the Russian Federation (Volgograd, Belgorod, Kaliningrad, Vladimir, Samara and Penza regions). The indicators of soil and land degradation for all test objects were a decrease in the content of exchangeable potassium, a decrease in the content of mobile phosphorus, a decrease in the content of humus, a change in the acidity index of soils. In addition, for the test objects of the Volgograd region, the indicator of land salinization was used, the Belgorod region - soil erosion, the Kaliningrad region - the indicator of the metabolic coef cient (qCO2) of soils. It was found that the minimum and maximum values of the specif c total damage from degradation can be detected for regions with a similar composition of soil cover (Saratov and Belgorod regions, respectively, where chernozem soils predominate). When the values of specif c total damage from soil and land degradation are close to each other at various hierarchical levels of spatial organization of regions (Vladimir, Saratov, Belgorod and partly Penza regions), in terms of intensity and scale of manifestation of the studied degradation processes, the agricultural farm is «typical» for the entire municipal district, and the municipal district is «typical» for the entire region.

T e spatial variability of the content of granulometric fraction d>0,25 mm in the arable layer of soddy-podzolic cultivated soil on an area of 18 hectares was studied. T e soil formed in the loess-like loam, underlain by moraine deposits. Samples were taken from the upper (0-10 cm) and lower parts of the arable layer (10-20 cm) following a random-stratif ed sampling scheme. T e total number of samples was 350 cores. T e average fraction content was about 22%, the coef cient of variation was 39-41%, the distributions were approximated by a logarithmically normal distribution. T e Spearman correlation coef cient between values at dif erent depths equaled to 0,87. T e spatial distribution cartograms were constructed by the ordinary kriging method using a spherical variogram model. It is shown that preliminary censoring of high sample values (quantile 0,95) gives better results when constructing a cartogram than removing a linear spatial trend and logarithm of the original data. Spatial structures with reduced and increased values were found on the site, the average linear sizes of which was about 100 m. Presumably, they were associated with the heterogeneity of soil-forming material.

Spatial and temporal variability of the vegetation index were investigated in the vicinity of the anthropogenic source of heavy metals. The analysis of the special points of the theoretical equation of the dependence of the concentration of photosynthetically active biomass on the resulting concentration of pollutants in the soil revealed the maximum permissible concentration of heavy metals in the soil. The results of its determination in the northern forest-steppe under the current level of anthropogenic pressure, according to MODIS materials, amounted to 12,3, according to Sentinel-2 - 12,5 mg/kg, respectively. A method for generalizing the macrokinetic patterns of the response of the living organisms to anthropogenic impact is proposed. The results of the environmental risk assessment showed that the probability of exceeding the threshold concentration is 74%. Based on the five-level quality scale and the indicator of soil state, the quality of soils and vegetation cover was ranked. The areas of the same resistance of soils and vegetation to the action of pollutants in the plant impact zone were mapped. Territories near the plant mostly correspond to the I and II categories of soil quality. The natural protection zone of the enterprise is allocated, and background territories are def ned.

The paper provides a comparison of the various techniques for investigation of radionuclide speciation in soils based on fractionation of radionuclides bonded with different soil components. The dates on speciation of environmentally signifшcant technogenic and natural radionuclides in soils contaminated from testing of nuclear weapons, accidents or incidents at radiation dangerous objects, mining and mineral products processing are presented. The review looks at inf uence of natural and anthropogenic factors on the forms of the radionuclide compounds like the radionuclide and soil properties, type of radioactive fallout and the time elapsed af er fallout on soil. It has been demonstrated that experimental details of radionuclide speciation provide the basis for estimates and projections their mobility in soils, availability for plants and development of recommendations on reducing their penetration into food chains.

With the rise in the number of fi res, the proportion of pyrogenic soils in Russia is constantly increasing. The objective of this study is to determine how contrasting environmental conditions can trigger wildfires and affect post-fi re recovery scenarios. Post-pyrogenic Arenosols, Podzols and Fluvisols have been studied in the taiga subzones: in the Pinezhsky and Pechoro-Ilychsky nature reserves at the European territory of Russia and in the basin of Sukhoi Polui river in the north of Western Siberia. We employed soil morphology description, analysis of anthracomass concentration (calculated as the sum of charcoal particles >0,5 mm) and a set of chemical methods. We demonstrate that some fi res dramatically change the direction of soil formation, causing: 1) loss of organic horizon(s); 2) partial loss of mineral horizon(s); 3) restart of soil formation if the soil stratum has been completely degraded. We propose to distinguish such varieties as pyro-extreme soils. Both weakly transformed full-profile soils (para-extreme) and strongly degraded soils (ortho-extreme) can coexist in the fi re-damaged areas. Ecosystems whose properties (e.g. climate, topography, fire-return intervals) predetermine severe fi re damage to vegetation and soil cover are proposed as pyrogenically vulnerable. Among studied factors, the post-fi re erosion has proven to be a predominant control over long-term changes in the direction of soil formation. We propose a concept of «fi re centers» for description of spatial heterogeneity in burning, which can be tracked by changes in the anthracomass concentration.
