“…Sukhoruchenko developed domestic programs PESTINS and PESTINL for computer simulation of the behavior of pesticides in agrocenoses of agricultural crops to assess the prolonged action and hazard of pesticides [3]. These programs make it possible to determine the nature of degradation and localization of pesticides in the components of the soil -plant system, as the degree of toxic effects on target objects taking into account biological effectiveness and environmental hazard, as well as to assess the local risks of using pesticides [4,5]. Academic V.A.Zakharenko for environmental assessment of technologies for the use of plant protection products in optimizing the phytosanitary condition of agrocenoses proposed as the main criteria to use the indicator Ld50, multiplied by the processing area of the used pesticide groups, as well as their half-life [6].…”

The biological and economic effectiveness of plant protection measures depends not only on the correct choice of pesticide, but also on the quality of its application to the processed target objects. The article discusses the results of assessing the quality of applying herbicides by spraying using low-volume spraying technology, ULV spraying without forced and forced precipitation of small droplets, and treatment with cold aerosol. To assess the impact of the quality of the application of plant protection products on the environmental safety of the use of herbicides, two main indicators were used: – uniform distribution of the working fluid over the treated area: – the amount of drift of small drops from the treatment area. The analysis of methodological approaches and regulatory documents for assessing the potential risk of pesticides for the environment in European countries and in Russia is given.Based on the obtained experimental data on the coefficients of variation in the distribution of the drug over the effective coverage width, an expert assessment of the drug overuse was carried out using various technologies. An expert assessment of the drift of small drops of the working fluid from the treatment zone was also carried out. A comparative assessment of technologies was carried out according to the indicated environmental safety indicators for the use of the herbicide Gezagard WP on potato plantings.

“…On the other hand, application of field electrophysical methods, which do not lead to any mechanical disturbances of soil cover, seems to be preferable [10][11][12][13][14]. Current ecological management of urban territories requires an operative assessment of ground conditions [15][16][17].…”

Geoelectrical Survey of Active Layer Depth in Urban and Mature Environments of Yamal Region

Active layer thickness and the depth of the permafrost are the basic features of the soil cover of the Arctic region. Urban ecosystems are characterized by disjunctive character of soil cover. Identification of separate soil bodies within the urban ecosystems, their spatial limitation and vertical stratification should be performed for adequate ecological assessment of urban territories. Methods of field electrophysics, which do not lead to any mechanical disturbances of soil cover, should be preferably used for both urban and natural environments. Studied soil profiles revealed significant differences in profile distribution of electrical resistivity values and active layer depths. Predominance of sand fraction in soil of Salekhard site (Spodic Cryosol) determines higher rates of thawing process compared to soil from natural site (Aquiturbic Cryosol), where clay is predominant fraction. Both soil profiles and their electrical resistivity curves are significantly affected by natural cryoturbation processes. However, vertical profile of electrical resistivity value in urban soil is more complicated and has a number of fluctuations due to higher rates of ground mixing, mechanical pressure and high amount of artefacts.

“…Large-scale research studies of Russian river's hydropower potential are currently held in Russia to determine the location of feasible sites for the hydropower plants construction [2][3][4][5]. In many countries, such as Slovakia, France, Italy, Norway, USA, Canada, Turkey, Malaysia and South Africa the same studies have been fulfilled in the past few years [6][7][8][9]. A significant part of the research studies is focused on solving hydropower related tasks with the use of GIS technology [10][11][12][13][14][15][16][17][18][19][20][21][22][23].However, recent large-scale research of hydropower potential of Russian rivers by S.V.…”
