Aim. To determine physiologically expedient rates of mineral nitrogen in winter rye production on sod-podzol- ic soils based on the orientation of the processes of biological nitrogen transformation in the plants rhizosphere. Methods. Field studies, gas chromatography determination of potential nitrogen fi xation activity and potential emissions of N 2 O. Results. The results obtained have demonstrated that the rates of mineral nitrogen, not ex- ceeding 60 kg/ha, can be considered physiologically expedient for winter rye production on sod-podzolic soils. Under the application of microbial preparation Diazobakteryn, there is a higher physiological need of plants for nitrogen, which allows increasing the rates of nitrogen fertilizers up to 90 kg/ha. Conclusions. The orienta- tion of the processes of biological nitrogen transformation in the root zone of plants is a reliable indicator of determining the appropriateness of nitrogen fertilization of crops.

Subject. The article updates the scientific view of the environmental protection greening and the special land use regime as a special city planning means of passive sanitary protection of people from the adverse aerial and technological impact and the recovery of the environment we live in. Objectives. I identify the specifics of designing and efficient operation of environmental protection greening as an inseparable part of the urban ecosystem. The article justifies the technique for strategic positioning of respective infrastructure projects in order to ensure the protective effect. Methods. The study relies upon general methods of analysis, systematization of existing viewpoints and published findings, graphic and logic analysis, matrix-based tools to choose an administrative strategy. Results. I analyzed the air-holding capacity of economic activity in regions and the outcome of air quality monitoring as a risk factor for public health. The article pinpoints operational difficulties in the environmental protection greening facilities and strategic approaches to addressing the issues in order to improve the environmental security of industrial zones. I determine new aspects of public relations and groups of criteria to assess the effectiveness of green infrastructure projects. The article provides the rationale for fiscal incentives for investors and public-private partnership of stakeholders. Conclusions and Relevance. Considering national projects, such as Ecology, Demography, Convenient Urban Environment, I emphasize the relevance of recovering and rehabilitating obsolete environmental protection greening facilities situated in industrial zones of industrially developed cities. Green projects should indeed comply with a set of progressive results of fundamental studies carried in various scientific areas. There should be fiscal incentives in terms of taxes and depreciation on special assets as the basis for the private-municipal partnership in green assets management in order to enhance the environmental security of industrial zones.

Subject. Considering the existing environmental situation, it becomes especially important for the State to regulate the anthropogenic footprint on the environment in the Russian Federation. Current amendments to the legislative framework for environmental security are intended to ensure the innovative development of regions concurrently with a reduction in adverse environmental effects and more active environmental policy. Objectives. The research is to devise methodological tools to evaluate the efficiency of environmental policy in regions. Methods. The research employs qualitative and quantitative methods of economic analysis, including statistical and content analysis, rating, matrix zoning. The dataset proceeds from the Federal State Statistics Service, governmental reports on the current environmental situation and environmental protection in the Russian Federation. Results. We propose our own approach to evaluating the efficiency of environmental policy. It may help trace the correlation between the quality of strategic documents and changes in environmental indicators for a certain period, flag the challenging areas in terms of the environmental policy implementation and outline possible development paths. The approach extends the list of quantification indicators in line with those ones adopted internationally and presented in the Environmental Security Strategy of the Russian Federation up to 2025. We evaluated the efficiency of the environmental policy referring to the regions of the Northwestern Federal District for the period from 2012–2016. Conclusions. Having analyzed the evaluation results, most of the Northwestern regions tend to be controversial and ambivalent in setting environmental goals and achieving them. The findings may prove useful as the analytical and data basis for articulating the environmental and economic policy of the regions.

The paper mainly analyses the environmental threats focusing on climate change to human security in Nepal. Major aspects of human security are interlinked and interconnected in our context. Among them, human security offers much to the vibrant field of environmental security in Nepal. Environmental threats are linked to the overall impact on human survival, well-being, and productivity. A great deal of human security is tied to peoples’ access to natural resources and vulnerabilities to environmental change. The major environmental threats in our context is the climate change which have widespread implications for Nepal, causing impacts to water availability, agricultural production, forestry, among many other detrimental effects. The critical threat of environmental security needs to be taken into serious consideration to save our succeeding generation. This article primarily interpreted the government action towards emerging environmental threat based on realist approach. For the study of theme of this article, descriptive and analytical research has been used to draw present major environmental threats in Nepal. With consideration to factors, this article attempted to identify the major environmentally vulnerable areas that are likely to hamper the overall status of human security in Nepal. This paper also tried to suggest the measures to enhance the environmental security considering prospects and policy focusing on Nepalese diverse aspects.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.
