The paper presents the results of researches of the modern ecological state South Bug and Aleksandrovskogo of storage pool the affected of the South Ukrainian power complex zone on hydrochemical indexes (main ions, mineralization of water, biogenic matters), which are the indicators of the ecological state of natural reservoirs. Research of the hydrochemical mode South Bug and Aleksandrovskogo of storage pool within the limits of the South Ukrainian power complex conducted during 2019. An analysis of the got data is as compared to those, which took place more early, rotined that the water masses South Bug tested substantial changes (on the indexes of the chemical state). The conducted researches rotined that chemical composition of water S.Bug and Aleksandrovskogo of storage pool had been characterized sufficiently by the high values of mineralization of water, maintenance of main ions, especially sulfate and to general inflexibility.The features of spatio-temporal changeability of the main hydrochemical indicators of quality of water environment are set. Tendency of gradual increase of maintenance of main ions and of mineralization of water is traced on the longitudinal type of the river. The gradual diminishing from the winter to the summer and increase of mineralization of water and main ions an autumn is traced in a seasonal aspect. It is known that the important index of the sanitary-hygenic state of natural reservoirs is content of biogenic matters. Worsening of the ecological state South Bug and Aleksandrovskogo of storage pool is set on maintenance biogenic matters. Modern researches rotined that and here took place changes are certain, namely: on an area in the district of South Ukrainian power complex zone something the concentrations of nitrate and ammoniacal forms of mineral nitrogen and phosphatic ions grew, that testifies to the decline of selfcleansing ability of the river and is the index of process second contaminations of the river.

The purpose of the research is to identify effi cient microfertilizers and growth stimulants considering biologi- cal features of new corn hybrids of different FAO groups under irrigation conditions in the South of Ukraine and trace their impact on grain productivity of the plants. The methods of the research are the fi eld method – to study the interaction of the research object with experimental factors of the natural environment, to register the yield and evaluate the biometrical indices; the laboratory method – to measure soil moisture, grain moisture content and grain quality indices; the statistical method – to evaluate the reliability of the obtained results; the calculation methods – for economic and energetic assessment of the growing techniques used. The results of the research. The paper defi nes the impact of microfertilizers and growth stimulants on the yield and grain quality of the corn hybrids of different maturity groups and on the economic effi ciency of growing them. The conclusions of the research. Under irrigation conditions of the Southern Steppe of Ukraine it is recommended that the following hybrids should be grown in dark-chestnut soils: early maturity DN Pyvykha, medium-early Skadovskyi, medium maturity Kakhovskyi and medium-late Arabat, using the growth stimulants – treating the seeds with Sezam-Nano and fertilizing with Grainactive at the stage of 7–8 leaves.

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.
