For the current stage of the development of soil science it is relevant to search for objectively existing interactions between the various soil properties. Solving this issue most appropriately should be based on the establishment of pedotransfer functions. Pedotransfer functions appeared at the time of the birth of quantitative soil science, when one of the properties of the soil tried to predict others when it became clear that everything in the soil is interrelated when it was established that there is a well-defined number of fundamental, basic properties of the soil, which is basically defines its other properties. Accordingly, the purpose of our work is to establish the diagnostic value of the individual soil physical properties of forest biogeocoenoses of the steppe by means of determining the existing interconnections between them and other properties and characteristics of these soils. The solution of this issue is one of the tasks of developing research on the soil physical properties of forest biogeocoenoses of the Ukrainian steppe zone. The diagnostic value of granulometric and structural-aggregate composition, density and permeability for determining the general state of soils due to the existence of certain interactions between the indicated parameters and other soil properties is considered. The granulometric composition is a fundamental soil characteristic that determines not only the physical state, but also all the main soil properties and regimes of forest biogeocoenoses of the Ukrainian steppe zone. The structural and aggregate composition is an important complex diagnostic feature of chernozem, which helps to reveal the peculiarities of their genesis under the influence of forest vegetation, in particular as a result of changes in the content and composition of organic matter, exchange cations, the influence of root vegetation systems, etc. The soil density, due to existing interactions with other soil properties, is an important diagnostic feature that reflects the features of their genesis and regimes, which determines the specificity of the ecological functions of the soils of forest biogeocoenoses of the Ukrainian steppe zone. Water permeability can be considered as a complex characteristic of soils, which to a certain extent reflects their granulometric composition, porosity, structural and aggregate composition, determines the features of the water-air regime. The differences of physical properties of zonal chernozems and chernozems, the genesis of which are connected with artificial and natural forest biogeocoenoses within the steppe zone of Ukraine, are analyzed. The relevance of the further search for relationships between physical indicators that are easily and promptly analyzed, and other soil properties for expanding diagnostic possibilities with respect to their genesis is pointed out.

At present, the return of fallow lands to agricultural circulation is an important and one of the topical issues of the whole world. Research related to the restoration of soil properties of fallows is of particular value. Therefore, it is necessary to know what processes occur in the vegetation and soil cover of fallows at the different stages of their development, taking into account local natural features. The paper presents the results of a survey of young (up to four years) and middle-aged (up to ten years) fallows of the forest-steppe zone of Western Siberia within the Novosibirsk region. It is established that in the first decade of succession in fallow areas there are two stages of overgrowth, and when analyzing the structure of plant matter, it is shown that the ratio of their fractional composition reflects the general tendency to restore the ecosystem that preceded plowing. Restoration of soil properties under young and middle-aged fallows is much slower. Data of humus content analysis allow us to conclude that its content is somewhat higher in the upper parts of the profile in middle-aged fallows compared to young fallows. The research on soil-physical characteristics and vegetation cover allowed us to note the trends of restoration of the initial state of soils.

Results of the studies on the floristic biodiversity of the kurgans in the Pontic desert steppe of the Black Sea Lowland (Kherson Region) are presented. Twenty-six of about 130 kurgans higher than 3 m, distributed over an area of approx. 1500 km<sup>2</sup>, were surveyed and the flora of 5 microhabitats within every kurgan (top, southern and northern slope, southern and northern foot) was examined. The richness of the kurgan flora is estimated at 305 species. Species of alien origin constituted 23% of the total flora, which indicates limited anthropogenic influence. Species of two classes, <em>Festuco-Brometea</em> and <em>Stellarietea mediae</em> were predominant, which also confirmed the semi-natural character of the kurgan flora. The lowest number of species was recorded on top, which was relatively rich in synanthropes, particularly therophytes (<em>Stellarietea mediae</em>). The north side was richer in species than the south side of the kurgans. Steppe species were the most stable and important component of the flora of the slopes (45-47% of the species represented the class <em>Festuco-Brometea</em>). The total flora of the foot contained more species and was more diversified than the flora of the slopes (although the mean number of species was similar in both habitats), but each species occurred at low frequency. There was a higher proportion of species which were introduced from the area surrounding the kurgans, e.g. weeds, halophytes, meadow species, as well as trees which are rarely found in the desert steppe zone. In spite of the small size of the kurgans, significant differences between the floristic composition of the various microhabitats were detected.

Abstract The influence of various tree species of forest plantations on the soil properties of the “Kamenno-Stepnoye Experimental Forestry” (Talovsky District, Voronezh Region, Russia) is considered. The aim of the study is to reveal the degree of transformation of the properties of chernozems under various perennial plantations, since forest reclamation is the most important measure to optimize the agroecological state of soils. The researchers note that different tree species have different effects on soil properties. However, this issue is still insufficiently studied and relevant. The research results showed the positive role of tree species on the structural and aggregate state of soils and their water-physical properties. It was found that tree species contribute to the optimization of soil density, humus and moisture reserves. It was revealed that the influence of different tree species on the agroecological state of chernozems is not the same. Thus, under larch (Larix siberica Ldb.) And maple (Acer platanoides L.), the maximum increase in the level of soil humus was observed, as well as a significant improvement in the physical and water-physical properties of soils. What makes this breed the most promising for use in soil protection of the steppe zone.
