INFLUENCE OF MULTIPLE-PURPOSE COMPOSITION COMPOST ON AGROPHYSICAL PROPERTIES OF SOIL IN DRAINED CULTIVATED LAND

Posted in 2019, AGRICULTURE, Issue № 5(83) May 2019 | 0 comments

The paper presents the data of long-term monitoring of the physical properties of soils within a variety of landscapes and under conditions of a different agricultural background, conducted at the agroecological testing ground of the FSBI ARSRIRL. The effect of multipurpose compost on the change in the basic agrophysical properties (density and humidity) of sod-podzolic soil within a finite morainal hill was shown. Soils under crops of grain-grass crop rotation were studied on a test field where 12 t/ha of multi-purpose compost were introduced and on a control field where fertilizers were not applied. The obtained data were processed by the variance analysis method. In the course of the research, it was revealed that the use of products of bioconversion of organic raw materials contributed to the decrease in the density of the arable layer of soil under grain crops by 1.60-5.04%. Under grasses, a decrease in soil density was observed only within the northern slope (by 0.86–3.38%). The spatial variability of soil moisture was significantly influenced by the structure of the soil cover, soil density, and the agricultural landscape structure of the territory. However, the character of the cultivated crops had the greatest impact on it. Under perennial grasses, soil moisture increased by 27.3-31.3% compared with cereals. The dependence of soil moisture on the use of multi-purpose compost has not been established. However, there is a tendency to decrease it in the lower part of the southern slope and at the top of the hill. The revealed patterns make it possible to develop measures for regulating the water-physical properties of the soil in the agricultural landscape and, thereby, to improve soil fertility and the environmental sustainability of the natural environment.

Posted in 2019, BIOLOGY, Issue № 5(83) May 2019 | 0 comments

The connection of the somatotypological and dermatoglyphic characteristics of athletes with their playing role was determined in the study. Forwards often have a “whirl” finger pattern, while the “loop” pattern dominates for defenders. Forwards exceed water polo players of other game roles in the overall body size, they have a little bit larger girths and larger absolute contents of muscle and fat components. Defenders are characterized by a greater length of a skeleton; their characteristic feature was the large lengths of the upper and lower extremities and their links. Also, in the study, it was revealed that the water polo players, who differed in game function, had different body types. Thus defenders have ecto-mesomorphic (60%) and meso-ectomorphic (40%) types of constitution, forwards have a greater variety identified somatotypes: endo-ectomorphic (40%), meso-endomorphic (30%), endo-mesomorphic (20%), mesomorphic (10%).

GROWTH RHYTMICITY OF ANNUAL TWIGS OF ALMOND-LEAVED WILLOW (SALIX TRIANDRA L.) AS PESTICID LOAD OPTIMIZATION FACTOR IN INTENSIVE TYPE PLANTING

Posted in 2019, BIOLOGY, Issue № 5(83) May 2019 | 0 comments

The authors present general characteristics of almond-leaved willow (Salix triandra L.): taxonomy, cytogenetics, practical importance as a source of twig for weaving. The authors analyzed the possibility of genetic protection of almond-leaved willow twigs from pathogens and pests in the paper. The necessity of the use of pesticides with a prolonged effect on the twig plantations of the intensive type has been substantiated. In order to reduce the pesticide load, they proposed to plan agroforestry measures which take into account the rhythms of development of annual twigs. In the model inbred population of almond-leaved willow seedlings of the third generation, the patterns of seasonal cyclicity of changes in the length of internodes were revealed with the use of amplitude-phase analysis. It is proved that seasonal trends in the dynamics of the length of internodes depend on the individual characteristics of seedlings and are due to the interaction of the lower unsynchronized harmonics with the oscillation period of 48…144 (288) days. The cyclical nature of the seasonal dynamics of the length of the internode, which does not depend on the individual characteristics of seedlings, in most cases is determined primarily by synchronized harmonics with a period of oscillations of 36 days and modulating harmonics with a period of oscillations of 24 days. Higher harmonics with a period of oscillations of 10…21 days have a slight modulating effect on the seasonal dynamics of the length of the internode. To optimize the pesticide load, they proposed to carry out triple treatment of plantations with a frequency of about 36 days.

EVALUATION OF THE EFFECT OF DETACHED WATER OF BOTTOM SEDIMENTS AND UNDERGROUND WATER ON THE QUALITY OF WATER OF IVANKOVO RESERVOIR

Posted in 2019, Issue № 5(83) May 2019, SCIENCES ABOUT THE EARTH | 0 comments

Ivankovo Reservoir is the main source of water supply in Moscow, and due to the increasing anthropogenic load on its catchment area and the deterioration of the quality of water supplied to the Moscow canal, the problem of its contamination with heavy metals is particularly relevant. The content of Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Fe, Mn in the near-bottom water horizons, pore solutions and the solid phase of bottom sediments were measured on the reservoir in the intra-annual mode.

Studies have shown that the proportion of heavy metal reserves in the pore solution is insignificant compared to their reserves in the solid phase, but the role of the pore solution in the processes of secondary pollution of the water masses of the reservoir is not limited to the reserves of dissolved elements. Part of the elements from the solid phase of bottom sediments can pass into the pore solution and further into the water mass – thus, the transition from the sediments to the water mass is carried out in transit through the pore solution. Also, the estimates made show that neither diffusion removal nor filtration can be real mechanisms for the removal of trace elements into the water mass.

GEOGRAPHICAL ASPECT OF INTEGRATION OF PERSONS WITH DISABILITIES IN SOCIETY

Posted in 2019, Issue № 5(83) May 2019, SCIENCES ABOUT THE EARTH | 0 comments

The article deals with the integration of persons with disabilities in society. Several scientifically based measures were proposed, they could potentially contribute to the involvement of persons with disabilities in socially beneficial activities. The fact that more than 12 million people with disabilities live in the Russian Federation indicates that this problem is relevant. However, there is not yet a single term, unified for all levels of legislation defining this category of citizens. The author believes that in relation to this study, a “disabled person” is a person, in order to remove the disabilities of which, it is necessary to develop programs that allow him/her to integrate into public life of civil, social and medical institutions (taking into account the territorial features of the external living environment). For the development of such programs, it is recommended to use the problem-program approach. Within the framework of the federal target program “Accessible Environment,” it is proposed to create organizational and management clusters, taking into account the specifics of resettlement when locating objects of social and medical infrastructure, popularizing the “accessibility map” project both among people with disabilities and among the organizations serving them.
