Studies were conducted in the forest-steppe zone of the Belgorod region. The soil cover was represented by Haplic Chernozems and Luvic Сhernozems. The aim of the research was to analyze and assess the accumulation in pea, white lupine and soybean plants of the main macro- and microelements. The materials of local agroecological monitoring 2015-2017 years were used for pea, white lupin and soybean sowings. It has been established that the highest average content of the main macroelements: nitrogen (6,26%), phosphorus (1,88%), potassium (2,52%), sulfur (0,3%) and trace elements: copper (11,7 mg / kg), nickel (5,15 mg / kg), chromium (0,42 mg / kg) are characterized by soy beans. The highest content of zinc (43,2 mg / kg), cobalt (0,88 mg / kg) and molybdenum (6,73 mg / kg) was recorded in white lupine beans. The lowest average nitrogen content (3,3%), potassium (1,38%), sulfur (0,14%), zinc (26,5 mg / kg), copper (3,85 mg / kg), molybdenum 0,39 mg / kg) was noted in pea beans. The lowest content of cobalt (0,14 mg / kg) was characteristic of soybeans. The mean phosphorus content, nickel and chromium in the white lupine beans and peas was similar and significantly lower than in soy beans.

Abstract The soil cover of the forest-steppe and steppe zones of the East European Plain is characterized by diverse soil combinations revealed during large-scale and detailed soil mapping against the background of a traditional zonal sequence of dominant automorphic soils alternating from the north to the south and clearly displayed on small-scale soil maps. The composition, configuration and functioning of particular soil cover patterns are determined by the soil forming factors acting within a given area. The elementary soil areas (detailed scale) and elementary soil cover patterns maps (large scale) of the Central Russian, Kalach, and Volga Uplands are created by both traditional and digital soil mapping methods. Low-contrasting soil combinations with the background Haplic Chernozems (Loamic or Clayic, Pachic) alternating with zooturbated Haplic Chernozems (Loamic or Clayic, Pachic) on convex elements of the microtopography and Luvic Chernozems (Loamic or Clayic, Pachic) on concave elements of the microtopography prevails under conditions of thick clay loamy parent materials and free drainage. Under conditions of shallow embedding by low-permeable clayey sediments, the soil cover includes Chernozems or Chernic Phaeozems with stagnic features in some part of the soil profile or even Mollic Stagnosols. The presence of shrink-swell clays of different ages leads to the formation of Bathyvertic Chernozems, Vertic Chernozems, Vertic Chernic Phaeozems and/or Pellic Vertisols. The presence of soluble salts in the parent material leads to the development of solonetzic soil complexes consisting of Protosodic or Sodic Chernozems and different types of Solonetzes.

Plowing up is a widespread type of anthropogenic transformation of soils and soil cover (SC) in the forest-steppe zone of Western Siberia. As a result of plowing up agrogenic transformation (agrotransformation) of soils causes their form and properties change, as well as the spatial characteristics of the SC. In the example of a model territory the features of changes in the component composition and structure of the SC of the Pre-Salair drained plain under the influence of arable press are studied. Automorphic soil formation prevails in the studied area, and zonal natural soils here are chernozems (clay-illuvial and migrate-micellar) and dark grays. These soils have an upper dark humus horizon, which in arable soils becomes an agro-dark humus horizon. In the studied area, an increase in number of the SC components was found due to the soils of the agrozems section and different types of agricultural soils, which leads to a diversification of the component composition. It was found that the component composition of SC shows high degree of its agrotransformation: area of arable soils is 55.6% of total area of SC. We also showed the sequence of agrotransformation for the chernozems of the model territory: chernozems, agrochernozems, agrozems, abraded agrozems, agroabrazems. Agrozems occupy a large area and have a classification diversity. Factors affecting the diversity of agrozems at the type and subtype classification level are identified: the degree of agrogenic transformation of clay-illuvial and migrate-micellar chernozems are distinguished. The low thickness of the humus horizon of soils in the pre-agrarian period during plowing leads to various degrees of their agrotransformation and classification divergence of soils. The SC structure is characterized by geometric parameters in accordance with the concept of V.M. Friedland. These are areas and dissection coefficients (minimum, maximum, average and median) of elementary soil areal (ESA) and soil combinations areal (SCA). Geometries of ESA and SCA are caused by the combined influence of terrain features and anthropogenic impact. ESA of agrotransformed soils (agrograys, agrochernozems, agrozems) have largest sizes, besides undisturbed automorphic soils; ESA of strongly transformed soils developed in temporary flow hollows have smallest sizes. The overall result of the agrogenic transformation of the SC on the studied area is a new spatial agrogenic structure. In the component composition of SC specific soils of different taxonomic levels appear.

The ecological condition of the soil cover of technologically disturbed areas was studied. It has been established that the general soil-ecological state of the plots with agricultural re-cultivation and self-restoration is characterized, as a good one, with the forest re-cultivation — as satisfactory. Communities of carabid beetles at the dumps of the forest-steppe zone of Siberia are formed according to the meadow type. In the surveyed dumps, in 30 years, the carabid beetles communities are gradually restored, but not in full strength. In the area with forest remediation, forest species begin to be settled, however, representatives of the meadow cenosis are also preserved. From this it follows that the forest direction of remediation requires more time to restore the population of carabid beetles, corresponding to the established biocenosis.

The Way

The contemporary condition of soil cover in Ukraine is characterized. The attention is focused onto widespread degradation processes in soils. The causes that determine the development of these negative processes are considered. The contemporary informational support for the condition of soil cover in Ukraine is estimated. In general, the current available information is of narrow-departmental nature, obtained by different methods and non-correlated monitoring programs. As a rule, it is stored in under-structured databases, incompatible with other information systems; mainly recorded on paper media unusable with modern technologies, whereby such information resources are diffi cult to be compiled together. These disadvantages are strong constraints against consistent usage of materials for evaluation, forecast and management of changes in the soil cover. The Soil Observation program should thereby be combined with Agrochemical Passportization and ecology-ameliora- tive monitoring; in other words, the application of innovative soil-agrochemical methodology is considered. Each individual type of surveys shall complement the others, and taken altogether, they shall constitute a con- sistent Information System, capable of solving the problems of assessing the condition, forecasting, manage- ment, usage and protection of soil resources. The monitoring procedures should be conducted on the basis of a new soil concept in line with unifi ed programs and methods, so as to meet European approaches to the maxi- mum extent. Such a technical composition enables getting information on present-day processes in soils, and is the only combination that actually helps us to “ecologize” our knowledge of soils, which is the leading trend in the scope of global soil-science. Thus obtained results will serve as a State-owned tool which would subse- quently facilitate the use and protection of soil resources all over the country, to be involved in a united global soil-information scope. The attention is focused onto social signifi cance of the information on soils and their fertility in terms of land resources optimization, as well as the formation of sustainable land use in Ukraine. Aim. To demonstrate the long-term effect of different ways of tillage of typical low-humus chernozem on the change in humus content and composition and the direction of transformation processes of organic fertili- zers. To study the changes in the structure of energy reserves in group and fractional composition of humus in typical low-humus light-loamy chernozem of the Forest-Steppe of Ukraine. Methods. Field, laboratory, microbiological, computational, mathematical and statistical. Results. It was determined that in conditions of long-term subsurface tillage the most effi cient humus accumulation occurs in the 0–20 cm layer of chernozem with simultaneous increase in its content in the lower part of the processed layer without any accumulation differentiation. Surface tillage leads to expressed differentiation in humus accumulation in the 0–20 cm layer of soil (0.005 % per year). When 6 t/ha of humus are replaced by 7 t/ha of by-products the intensity of humus accumulation is decreasing regardless of the way of tillage, but humus accumulation was found to be the most effi cient for subsurface tillage. The application of subsurface tillage leads to the increase in the ratio of C HA : C FA , which is conditioned by the increase in the humifi cation of plant remains of by-products in the 0−20 cm layer of soil by 110–112 % – for subsurface tillage, and by 105 % – for surface tillage. Conclusions. It was established that systematic subsurface tillage of typical chernozem of the Left-Bank Forest-Steppe of Ukraine leads to the structuring both of the total reserves of energy С org , and its quality content, aimed at the increase in the intensity of the processes of humifi cation and accumulation of organic carbon, and the decrease in miner- alization. The ratio of energy reserves С org of humic acids to fulvic acids in the 0−30 cm layer of chernozem is 1.85−1.87 regardless of the way of tillage, which testifi es to the repeatability of humus accumulation, but the total reserves of energy С org was higher for subsurface tillage (+ 31 Teracalorie/ha) compared to deep plough- ing. As for the surface tillage, the energy enrichment was at the level of deep ploughing.
