The state of soil microbiocenosis in the zone of high anthropogenic pollution was studied. The studies were carried out in four farms of the Voronezh region, one of which is located at a distance of 30 km from the enterprise for the production of mineral fertilizers and three – 5-10 km away. Sanitary and bacteriological condition of the soil was assessed in spring, summer and autumn by the total number of bacteria at 1,0 g, coli titer and perfringens titer, and agrobiological – by the content of nitrifying and ammonifying bacteria. It has been established that toxicants emitted in the form of steam into the environment by the enterprise for the production of mineral fertilizers, worsen the sanitary and agrobiological state of the soil in considerable degree, especially in farms located near the source of contamination.

The paper deals with the theoretical analysis of peculiarities of agricultural nature management influence on the components of natural environment in the Voronezh Region. A retrospective analysis of soil research reveals a degree of its degradation. Dynamics of agro ecosystems development and the degree of change in the natural background of vegetation are determined; the peculiarities of agricultural impact are shown. The value of land resources in the Voronezh Region is determined by their fertility. The State Center of Agrochemical Service Voronezh and the State Station of Agrochemical Service Talovskaya control the structure, dynamics and condition of soils. As a result, soils of agro ecosystems on phosphorus, potassium, humus, acidity, heavy metals, mineral fertilizers and pesticides are comprehensively monitored. The Land Committee for the Voronezh Region reveals violations of the land legislation. Agro ecosystems have an unclosed cycle of biogenic elements. This is related to the loss of nutrients during harvesting and the activation of erosion processes. Changes in the balance of basic soil nutrients reduce the quality and yield of crops. Agro ecological monitoring includes systematic observation, study and analysis. In this regard, there is a need for research into the significant magnitude of the associated factors. The existing system of regional monitoring is based on the repeatability of soil, agrochemical and bacteriological studies of agroecosystems. Both continuous and local agro monitoring is conducted. It should be noted that agroecosystems of the region are insufficiently provided with biogenic elements, microelements and in this connection there is a need to create a model of balanced agricultural environmental management.

Abstract The effects of various concentrations of herbicide Euro-Lightning Plus on the state of microbiota in the root zone of sunflower have been studied. Soil of plant rhizosphere and interrow soil after treatment with the herbicide at the doses of 1.2 and 2.5 l/ha were taken for the analysis at the end of sunflower growing season. Rhizosphere soil without herbicide application was used as a control. The herbicide was applied at the stage of 2–4 true leaves. The total number of bacteria in the rhizosphere of control plants was 12.82 million CFU/g of soil while in the rhizosphere and in the interrow soil after herbicide treatment with a dose of 2.5 l/ha it decreased by 1.4–1.5 times. A general trend of decline in number of the basic ecological and trophic groups of bacterial microorganisms with the increase in a dose of herbicide was established. Microbiological coefficients that reflect the functional activity of the microflora indicate changes in its biological activity under the influence of the herbicide Euro-Lightning Plus, which leads to deterioration in the agroecological state of the studied soils. It was also found that herbicide application resulted in a rearrangement of micromycete complexes in the root zone of sunflower which led to a two-fold reduction, compared to the control, of mycobiota species diversity and the formation of a specific species composition of mycocenoses. A greater genus and species diversity of fungi of the microflora in the rhizosphere of control plants, in comparison with the herbicide-treated soil, was revealed. A reduction in species diversity of the genus Penicillium from six species in the control to 1–2 species in the rhizosphere of experimental sunflower plants as well as the absence of rare saprophytic fungi species from the genera Acremonium, Verticillium, Trichoderma and Paecilomyces were noted.

AbstractThis article aims to explore the views of the Turkish elite on the state of polarization in Turkey. By identifying four political frames—namely, harmony, continuity/decline, conspiracy, and conflict—that selected Turkish political and civil society elites use in discussing the phenomenon of polarization in the country through their contributions to a workshop and in-depth qualitative interviews, the article finds that there is a considerable degree of polarization among the Turkish elite regarding their views on the presence of polarization in Turkey. Moreover, this overlaps with the divide between the government and the opposition in the country. An analysis of the justificatory arguments employed in constituting the aforementioned frames shows that, while those elites who deny the existence of polarization seek its absence in essentialist characteristics of society, in reductionist comparisons with history, or in internal/external enemies, those who acknowledge polarization’s presence look for its roots in political and institutional factors and processes. The article highlights how, given the denial of polarization by the pro-government elite and the substantial gap between the two camps’ justificatory narratives, the currently reported high rates of polarization in Turkey can, at best, be expected to remain as is in the near future, barring a radical change in political constellations.

In sugar beet production, one of the most important factors that affect the yield, apart from genetic properties, is the use of mineral fertilizers. Considerate amounts of mineral fertilizers are used in sugar beet production. However, if agroecological conditions are not optimum, mineral fertilizers cannot be completely absorbed, which may lead to soil contamination. Therefore, research has been focusing on ways of using atmospheric nitrogen by means of nitrogen-fixing bacteria. Numerous researches have proved that one part of mineral fertilizers can be replaced by biological nitrogen. The aim of this research was to determine the effect of genotype, azotobacter and the amount of mineral fertilizers on the root yield of sugar beet and on the microbiological activity of the sugar beet rhizospheric soil. Three hybrids of sugar beet were used during the two years of the research. The seed of the hybrids was inoculated with three strains of azotobacter. Various amounts of NPK were used (0;30;60;90 kg/ha). At the end of the vegetation period, the following were determined: root yield, total number of bacteria, number of azotobacter, oligotrophic bacteria, ammonifiers, fungi, and actinomycetes in soil. Dehydrogenase activity was measured. The results were processed statistically (analysis of variance for factorial trials) and the effect of the factors was determined upon the expected mean square values. The yield was mainly affected by the amount of mineral fertilizers. However, the effect of mineral fertilizers was different with different inoculation treatments. The effect of the examined factors was dependant upon genotype, amount of mineral fertilizers, inoculation and the year of trials. The interaction between genotype, mineral fertilizers, inoculation and the year of trials was the factor that had the greatest effect on the number of almost all the examined soil microorganisms.

The Russian Federation

The timber industry complex of the Russian Federation ranks fourth among all branches of the country, because in terms of forest area Russia ranks first in the world (8148895 km2), which is about 49.76% of the total area of Russia. The timber industry complex is a complex system and consists of four components (logging industry, woodworking industry, pulp and paper industry, wood chemical industry). Particular attention is paid to this industry in Eastern Siberia, Western Siberia and the Far East, because these regions have the greatest forest cover. In sparsely wooded regions, the timber industry is not a priority and little attention is paid to it, both by the state and by investors. In this article, we examined the state of the forestry complex of the Voronezh region, the forest cover of this territory is only eight percent of the entire territory of the country, all forests are protective, therefore the volume of timber is carried out thanks to sanitary felling and is about 285 thousand m3. In this region there are about 20 large and medium-sized enterprises involved in the timber industry and about 40 small private enterprises. The main problem of the timber industry complex in a low-wooded region is low-quality products, imperfection of regulatory legal acts at the regional level, and lack of investment. In this regard, measures were proposed that will contribute to the development of the timber industry complex in the low-forest region.

The article analyzes the state and dynamics of the main indicators of agricultural development in the Horodok district. The national economic and ecological aspects of the development of the complex and the factors influencing its condition were studied. It was indicated on the connection of the efficiency of agricultural production with the state of soils, water, infrastructure provision and the general state of the economy of the territory. The main negative impacts of intensive agricultural development on natural ecosystems and the state of the environment are outlined. The basic link of agrosphere in the region is agriculture. In the conditions of the Horodok distric, the main risks of the development of agriculture are related with a high proportion of land involved in agriculture, and a high indicator of their rooting: environmentally sustainable systems account for less than half of all land. In addition, the aggravated structure of agro industrial production is associated with the dominant role of plant growing, which is mainly represented by monocultures, which increases the need for mineral fertilizers and pesticides, enhances instability of agro ecosystems and increases the risk of contamination of surface water in the district. In terms of efficiency and productivity, the agro complex of the district is close to the regional average. Attention is need to the poor state of infrastructure provision and the potential problems of labor resources. Strategic directions of agrosphere development today are connected with the formation of rational, ecologically safe and sustainable land use development, and from the economic point of view it is necessary to develop the most effective directions. In order to ensure sustainable growth of the agricultural complex of the region, attention should be paid to the diversification of crop production, balanced support to the animal sub-sector, social and infrastructure problems, and to outline the directions of exit of enterprises of the district into world markets.
