In this study, the effect of endogenous and exogenous factors on the soil microbiome in the primitive forest ecosystems of the Carpathian Biosphere Reserve (Shyrokoluzhansky massif) in Ukraine was been investigated as temporal variation. These unique ecosystems have a model value for investigating the distinctive soil microbiota, such as the structure of their microbial communities, the number of major ecological groups, and their spatial variability. For this aim, microbial communities in the soil were been researched in the years 2008 and 2018 by field sampling, and georeferenced field data has been collected for mapping process in geographic information systems (GIS). Microbiological studies on soils in the research area were been carried out according to the general methods used in soil microbiology. Spatial distribution of microbial communities was been transformed to interpolated raster maps for the years 2008 and 2018 by utilizing Kriging interpolation method in GIS. The relationships of soil microbial communities with elevation, climate, and soil variables were also investigated by utilizing available climate (annual mean temperature and annual precipitation amount), elevation, and soil (sand-silt-clay, organic matter, pH, and cation exchange capacity) raster maps. Statistical analyses were been conducted by utilizing test of normality (Shapiro–Wilks), descriptive statistics, t-test, correlation, and linear regression analyses. Significant increases in the number of microorganism communities were been detected from 2008 to 2018, with the most significant increases seen in oligotrophs and pedotrophs, followed by ammonifiers and bacteria. While ammonifiers and bacteria constituted the first group similar to each other in terms of the number of microorganisms, the second group was been formed by pedotrophs and oligotrophs. The differences between these two groups of microorganisms also reflected in their relationships with the independent variables. The strongest associations with microorganism communities were been found between elevation, Cation Exchange Capacity (CEC), precipitation and temperature variables. While ammonifiers and bacteria showed a negative relationship with elevation, CEC and precipitation, and a positive relationship with temperature, pedotrophs and oligotrophs showed a positive relationship with altitude, CEC and precipitation and a negative relationship with temperature. Strong relationships were been modeled. Temperature and precipitation values also increased significantly between 2008 and 2018, giving some clues about how global warming affects the geographical distribution of microorganism communities. *Corresponding author.

IntroductionThis paper presents comparative studies on the content and structure of organic matter (OM) and the activity of microbiological cellulose destruction in three types of Ukrainian soils intensively used in agricultural production.MethodsThe highest content of humus in the arable layer (4.9%), OM (410 t ha−1), and total carbon (30.9 mg C g−1 soil) was determined in chernic phaeozems, which is 2.2–2.5 times higher than in albic retisols. The soil of natural ecosystems is characterised by a high content of microbial carbon (Cmic) in the carbon fraction of organic soil compounds.Results and discussionIn arable soils, the content and reserves of humus and soil organic matter (SOM) have decreased by an average of 1.5–2 times. The most considerable loss of humus reserves in the soil profile was identified in albic retisols (1.96–1.44 times) and the smallest in chernic phaeozems (1.27–1.81 times). During the long-term systematic application of mineral fertilisers, the Corg content decreased by 8-21% in chernic phaeozems, 12-33% in greyzemic phaeozems, and 6–38% in albic retisols. A significant difference of 2.1–8.0 times was determined regarding the number of aerobic cellulolytic microorganisms and 1.3–3.3 times in the potential cellulolytic activity of the studied soils. The high number of cellulose-destroying microorganisms is characteristic of chernic phaeozems with a high content of OM in the soil; the advantage over other types of studied soils was 1.4 times and 7.8 times for greyzemic phaeozems and albic retisols, respectively. Among the studied soil types, high values of CO2 emissions were identified in chernic phaeozems. Intensive agricultural practices in Ukrainian soils have significantly altered the content and composition of organic matter, leading to reduced humus and soil organic matter reserves. The study also underscores the importance of considering the abundance of cellulose-destroying microorganisms and their potential activity in assessing soil health and sustainability.

“…With the increase of anthropogenic impact on the soil, the relationships in the soil-plant system are becoming more complicated, and the issue of soil interaction in the ecological system is topical (Symochko et al, 2021;Symochko et al, 2023;Litvinova et al, 2023). It should be noted that the process of degradation of acid-alkaline soil properties determined by the chemical composition of the maternal rock and by the level of application of fertilizers, especially nitrogen, by the removal of calcium with the harvest and its leaching from the soil profile (Bartkowiak et al, 2016;Smith et al, 2016).…”

The research aimed to analyze the cation-anion composition of the soil solution in dark-grey podzolized soil under the influence of long-term anthropogenic factors. Over the extended application of both mineral and organic fertilizers, changes in the cation-anion composition of the soil were observed, depending on the dosage of mineral fertilizers and their distribution within the soil profile. When the amount of mineral fertilizers was increased from 265 kg NPK per hectare to 397 kg per hectare, a noticeable decrease in soil solution pH was observed, with pH levels dropping to 6.1 and 6.0, as compared to the control variant without any fertilizer application, which exhibited a pH of 6.3. The application of mineral fertilizers and manure additionally enriched the soil with ions of organic and inorganic acids, what became the reason for the redistribution between mobile and immobile forms of calcium and magnesium in the direction of increase of their mobility beyond the soil profile. The greatest accumulation of sulphate was observed at a depth of 160-280 cm due to the migration of their water-soluble forms. The main quantity of chlorine was moved and accumulated in the soil layer of 120-280 cm, and the increase of mineral fertilizers increased the content of chlorine in the aeration zone.
