The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands
The article gives a general assessment for meliorative state of soils at the rice irrigation systems in the Ros-tov region. The indices of soil salinity, alkalinity, sodicity, calium content in soil exchangeable com-plex of dark chestnut soils at different crop rotations and water loadings are afforded
The article presents results of the assessment of the
efficiency of non-hormonal preparations which were
not earlier applied in culture in vitro with high physiological
activity (the preparations received by production
of furfural, and also derivatives and compositions
of organic acids) during regenerations of microshoots
of plum, comparison of their influence with
influence of growth regulators which are traditionally
used in clonal micropropagation. These experimental
preparations were received when processing waste of
agricultural production. In this work we used: technology
of clonal micropropagation of plants of in
vitro, statistical data processing by method of the
dispersive analysis. The objects of researches were
microshoots of plum of a Stanley variety. We have
established that on mediums with the preparations
"Universal", sodium succinate, potassium succinate,
amber acid, L-1 the large, intensively colored plum
microshoots develop surpassing control (medium
with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid
of 0,5 mg/l) in morphometric parameters. Thus, the
preparations "Universal", sodium succinate, potassium
succinate, amber acid, L-1 in concentration of 4,0
mg/l proved as the growth factors which are favorably
influencing on plantlets’ regeneration and a qualitative
condition of microshoots of plum
The article is devoted to the evaluation of the
influence of the interest rate policy of the central
bank (CB) on the deposit policy of commercial
banks. The author analyzes the dynamics of the
Central Bank's key interest rate, weighted average
interest rates to individuals funds obtained raised by
credit organizations. Particular attention was paid to
regression analysis to determine the dependence of
rates on deposits of individuals from the Central
Bank's key rate. The authors presented the forecasted
values of interest rates on deposits of individuals,
which clearly demonstrate the current situation of the
deposit policy of commercial banks. A number of
indicators that affect the change in interest rates on
deposits of individuals are considered. In addition,
the main positions on improving the deposit policy
are presented. The conclusion is drawn that interest
rates on deposits depend on a whole spectrum of both
external and inner banking components. Each bank
develops its own deposit policy, determining the
terms, types of deposits and their interest, terms of
conducting deposit operations, relying on the
specifics of their activities and taking into account
the factor of competition with other banks and the
inflationary processes that occur in the economy
Based on the analysis of the national literature about the migration of the peoples of the North Caucasus, the author concludes that the migration of highland people is changing in many ways the ethno-demographic situation; changing ethnic and cultural image of immi-grants, which, in turn, influenced the evolution of men-talities of highlanders. The dialogue with the new neighbors had mutually enriching character in general. The purpose of this article is to identify the impact of the migration on changing of the mentality of the peo-ples of the North Caucasus
This article reviews the results of studies on the impact of the nutrition background and the use of the Bereke GN growth stimulator on the yield and quality of early ripe potato variety Marabell in southern Kyrgyzstan. Early potato yields were largely dependent on the use of the Bereke GN growth stimulant. The highest yield was identified with the integrated use of a growth stimulator provided the planned yield, and averaged 29.97 t/ha. Also, in the experiments conducted, the yield of early potatoes was largely dependent on the climatic conditions of the year under study. The structure of the crop of early potatoes has been analyzed. In case of complex application of growth stimulator, also in case of treatment of seed tubers with growth stimulant, thickness of early potato plants is increased and on average in three years there was an increase by 0.32 and 0.52 thousand bushes per 1 ha.
The structure and marketability of the early potato harvest were analyzed in detail, depending on the background of nutrition and the method of application of the Bereke GN growth stimulator
This article is devoted to the influence of petroleum and petroleum products on the natural environment. There are the chemical composition of petroleum and the reasons for its detrimental impact on natural components. The pathways of petroleum and petroleum products in the natural environment were listed. There is a characteristic of the impact of these substances on all components of the natural environment, including soil, hydrosphere, living organisms. Consequences of such impact on each of the elements were listed. There are methods of fighting oil pollution and the need to make their application more expressed, as well as developing new, more effective ways
Food security of the population is now one of the major policy goals of the world community and individual countries. In the context of the global currency and financial crisis, that hit the economies of many countries, food security is particularly important. The article examines the current state of world food situation, highlighted the reasons for the crisis in this area. The authors defined the institutional framework of supranational regulation of food relations in the form of an international organization that is designed to provide the best of the Food Balance between the two countries through efficient production and distribution of agricultural raw materials
