EXPERIMENTAL RESEARCH AND MODELING OF PACLOBUTRAZOL MIGRATION IN SOIL
04.00.00 Geological-mineralogical sciences
DescriptionIn this study, we have investigated the migration of paclobutrazol in the sod-podzolics soils. The migration of pesticide was restricted with 5 cm in the field study. Paclobutrazol was found in 11 days after application in the lysimeter’s water samples, though the pesticide is moderately mobile. The lysimeter study showed that the risk of ground water contamination would exist if application of paclobutrazol was on the sod-podzolics medium loamy soils. The modeling by PEARL 4.4.4 and MACRO 5.2 simulated the migration of paclobutrazol until 18 cm in the soil. MACRO was able to predict the leaching of pesticide. The simulated paclobutrazol losses by leaching were consistently lower than the observed

Description
Considered in the study, there are specific features and stratigraphy of the snow cover in the region of the mountain claster of Sochi (Krasnaya Polyana) during winter of 2016-2017. We have analyzed patterns of snow thickness distribution, its dependence on the absolute elevation, slope exposition and landscape type. Conclusions were made about the necessity of the regular study of the structure and quality of the snow cover for the purpose of mountain skiing development

Description
In the article, we consider climatic conditions during the cold period of the year in the mountain claster of Sochi. We have analyzed variability of time series of air temperature and precipitation sums at meteostation Krasnaya Polyana. We have established, that average daily temperature in the cold period was growing during the last thirty years. This process was accompanied by decreasing of daily temperature amplitides. Winter of the year 2016/17 is characterized by early beginning of snow accumulation because of comparatively low temperatures in December 2016. This was the reason in general for comparatively more dense snow cover and to more frequent avalanches

MATRIX ORGANIZATION OF SOILS OF RICE AGROLANDSCAPES
06.00.00 Agricultural sciences
DescriptionAcidic properties of the mineral matrix of meadow chernozem and meadow-boggy soils of Krasnodar region are characterized by a total adsorption capacity of ammonia in the range of 32-61 µmol / g. The lowest acidity of the matrix was observed under conditions of permanent rice cultivation for 80 years (32- 33 µmol NH3/g). The mineral matrix of rice soils depends on the meliorative state and the granulometric composition of these soils. At low fields of meadowboggy soils, heavier in granulometric composition, the total acidity of the mineral matrix is 51- 53 µmol NH3/g on high checks of lighter meadow chernozem soils – 34-45 µmol NH3/g. In the upper soil, with a less acidic matrix, the Fe3+ content increases and the amount of Fe2+ decreases. The reverse pattern is found in the lower soil with more pronounced acidic properties of the matrix. A proportional relationship between the humus content and the acidic properties of the mineral matrix is found. The highest yield of rice is formed on meadow chernozem soils with a less acidic mineral matrix

LAMPENFLORA OF NOVOAFONSKAYA CAVE
DescriptionNovoafonskaya cave is located in Abkhazia. It is equipped for visits in 1975. The cave has permanently installed lighting. In caves with artificial lighting, a vegetation of cyanobacteria and algae, bryophytes and ferns can be found around lamps. The development of lampenflora is a typical problem for cave management. We have identified 69 species of phototrophs in Novoafonskaya cave: Magnoliophyta 2 species, Pteridophyta 6 species, Bryophyta 11 species, Cyanobacteria 34 species, Bacillariophyta 9 species, Ochrophyta 2 species, Chlorophyta 5 species. The article considers main habitat of lampenflora and gives their characteristics. We have also revealed predominance of cyanobacteria in the cave

Description
The present article is devoted to the revealing of the influence of the innovation restructuring on the structural stability of economic complexes and subcomplexes. In this work there was taken the effort to determine the connection between the achievement of stability of social-economic system and technological limits of its new equilibrium condition and as well as the necessary restructuring because of innovation changes. In the work there was underlined that the achievement of the ideal condition of equilibrium (harmony) of multilevel economic system and its long being in this condition is the aim to which the system speeds under the influence of the sum of factors. The equilibrium in such systems practically links with the notion of aimed development. The mathematical analysis of the realization of the law of structural stability, more known as the “law of the least”, showed that: -The potential of stability of each component of economic system must be determined by the conditions of influence on it by the external environment; -At the uniform (homogenous) influence on all components of the system, we should follow the absolute equal stability of all elements of the system. -It is obviously that it is wrong to increase the potential of stability of the rest elements of the system higher than the potential of it’s weakest element because it will not supply with the rise of performance and effectiveness and will lead only to non-productive and ineffective use of additionally spent resources. Firstly, it is necessary to reveal the weak element and to rise its potential and to increase the potential of stability of the rest elements in accordance with the rise of the potential of the weak element for the further rise of the performance and efficiency of the production in such economic system. -At the diverse (heterogeneous) influence on the system, we should aim to the absolute stability of all components of the present type of the influence. At the concentrated influence when the external influences always are directed to the more instable and weak components and the stability of the system is determined by the least stable one, it is enough to get it out from the stable equilibrium to direct the system on the least stable components. -At the innovational changes of techniques and technology in economic systems, the technical and technological proportions and “chain connections” between branches in the economic complex are changed. It, in its turn, leads to the necessity of revealing of optimal proportions of different elements of the economic system and the whole chain at its equilibrium. It leads to the change of ranks in searching of the weak element as well and along with it the priorities in the development of the system. At the analysis and the assessment of innovation development of the economic system it is necessary along with other factors to take into account the results: analysis of its structural stability of the “weak element”, revealing of “weak element”; working out of the arrangements on the increase of partial structural stability of the “weak element” of the economic system; working outs of arrangements on the increase of potential of the structural stability of the rest elements of the system adequately to the rise of stability of the “weak element” and with an account of influence of its size and dynamics of the further rise at the increase of potential of stability of the rest elements of economic system. All it allows to increase the performance and effectiveness of the system in whole
