Purpose. Investigate the socio-ecological conditions of existence of the recreational zone - Karpivsky Garden in the Novobavarsky district of Kharkiv for its further restoration and improvement. Меthods. Field, atomic absorption spectrophotometry, mathematical and analytical methods of information processing, conditional interrogation method. Results. Field research consisted of sampling of drinking water from an underground source in the garden, sampling of soil and vegetation. The study of drinking water from an underground source on the territory of Karpivsky Garden was carried out by chemical composition, quality indicators, organoleptic indicators. It is determined that the quality of drinking water meets the requirements of DSanPiN 2.2.4-171-10. The highest indicators in soil and leaf samples were determined in cities with a large amount of transport. Background concentrations of excesses are also not observed. A sociological survey of the residents of the district, who are visitors to the garden, was conducted in order to identify their desire to restore and equip the Karpivsky Garden. The questionnaire consisted of 12 questions. In restoration and improvement of the Karpivsky Garden. The variant of the organization of functional total, 20 people were interviewed. The survey showed the interest of the population of the district in the zones of a garden is offered Conclusions. Karpivsky Garden, which is located in the Novobavarsky district of Kharkiv, currently has all the environmental and social prerequisites for the restoration and further use of it for recreation of residents of the district in case of landscaping - installation of garden equipment and reconstruction of drinking water source.

Purpose. To study the socio-ecological state and ways of financial support for the restoration of the recreational zone of the Kholodnogorsky district of Kharkov. Methods. Field, atomic absorption spectrophotometry, mathematical and analytical methods of information processing, the method of integrated rating evaluation, the conditionally questioned method, the concept of the full economic value of the natural good. Results. It was revealed that the ecological state of natural components on the territory of the object of study allows creating conditions for qualitative rest of the inhabitants of the district, which in turn are ready to make: one-time contributions for restoration of the park area were revealed by 28% of respondents; 16% of respondents found their annual charity contributions; Personally, 43.5% of respondents have taken part in the restoration of the park's territory. Conclusions To meet the needs of different categories of visitors will help create a multi-functional park on the research site. Comparison of constant one-time costs for measures and total investment by the residents of the district indicates a positive net effect from the reconstruction of the facility.

A modern study of the role of silicon in the physiology of cultivated plants, in the soil fertility and in the production of quality and environmentally safe plant products remains one of the pressing and in-demand in practice. Purpose. Assessment of environmental and economic efficiency of modern methods of growing vegetables. Methods. Field, atomic absorption spectrophotometry, variance. Results. Field studies have been conducted on the plot of land in the village of. Orihikka of the Lubny District of the Poltava region during 2015-2016. In the autumn of 2015, an experiment with the following plot variants was planted on the plots: 1. Control - a plot without fertilization; 2. control – +2 foliar feeding; 3. N60P40K60; 4. N60P40K60 + 2 foliar nutrition; 5. 30 t / ha semi-perforated manure; 6. 30 t / ha semi-permafrost + 2 extra root feedings. The area of each site was 15 m2. Repeat options - triple.For siliceous-potassium foliar nutrition, complex fertilizers containing silicon and potassium "Quantum-AQUASIL" were used. The agrostatus of our choice is the steel plate feeding of vegetable plants of tomatoes and sweet pepper, which is carried out by 0.5% solution of the preparation by standard spraying in the evening in the second, fourth and sixth variants of the experiment. Two treatments were carried out: the first-in-phase of budding, the second - at the beginning of the formation of fruits.Researched ahrostatus not cause soil contamination with heavy metals. The maximum increase of harvest tomatoes in the experiment is 13.2 kg / ha of sweet pepper in the experiment is 5.2 kg / ha on the background of manure and foliar nutrition siliciclastic-potassium fertilizer. The same results were obtained for the variant with the introduction of complete fertilizer and foliar nutrition siliciclastic-potassium fertilizer. Against the background of manure siliciclastic double-sheet feeding potash contributed detox effect with respect to heavy metals, pollutants and also helped to shape better trace element composition.Conclusions. It is shown that the most appropriate to the ecological-economic approach is the cultivation of vegetable crops (tomato and pepper), with application of organic fertilizers and double silicon-potassium foliar treatment.

For example farm Vasil region Zaporozhye region conducted environmental and agrochemical examination of soil and irrigated water, as defined by ecological and economic assessment of land use. As a result of agroecological assessment of agricultural land in small farms and research shows the necessity of a series of measures to stabilize and improve the quality of the soil to ensure ecological balance agrocenosis.
