Hydroponics is a perspective direction of development of modern agriculture that provides perennial growing of main species of vegetables and greenery on small areas and with minimal expenses of water and fertilizers. This technology allows to get large enough harvests of fresh vegetables in big cities including office and living premises.
Last time entrepreneurs and inventors pay a lot of attention for elaboration of more effective methods of hydroponics and equipment for their realization in direction of decrease of using areas, economy of water, nutrients and increase of air supply and plants capacity.
There are several known methods of hydroponics: static solution culture, continuous-flow solution culture (NFT), deep water culture, passive sub-irrigation, flood and drain sub-irrigation, run-to-waste system, top-fed deep water culture, rotary system, aeroponics, fogponics. Commercial and industrial use got the first three from above mentioned methods. Herewith the method of static solution culture does not provide of necessary saturation of plant’s roots with air. Under realization of the method of continuous-flow solution culture are possible little buffering against interruptions in the flow (power outages), water logging in some channels, besides there are limitations for maximal length of channels (12 – 15 m). The method of deep water culture in industrial scales is used mainly for growing of lettuce. The other mentioned methods are not enough effective from point of view of commercial utilization.
The improved hydroponic installations, presented in the article, were elaborated with consideration of such demands: versatility of use (a possibility of growing of various species of plants); harmonies optimal provision of crops with water, nutrients, light and air; maximal use of premise’s space; a possibility of re-space during of the growth period, increase of area for each plant and support of its stalk and sprouts. Also, the formulas for definition of main parameters of the elaborated installations are presented in the article.

Publisher Vinnytsia National Agrarian University
In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
