The use of centrifugal disk fertilizer spreaders, the axes of which are set obliquely, in the technological process of mineral fertilizers provides an increase indicators characterizing the spreading of technological material in the direction of its scattering, at a greater distance than fertilizer spreaders with vertical axis of rotation. Thus, the hypothesis of the possibility of increasing the working width of the machine for applying mineral fertilizers by equipping such machines with centrifugal disk fertilizer spreaders, the axes of which are set at an angle, is confirmed.
Experimental research was conducted using the developed methods and current state standards, regression analysis, statistical methods of processing research results, standard and specially designed experimental equipment. The calculations were performed using the software environment Microsoft Office Excel 2007.
As a result of experimental researches it is established that the centrifugal disk fertilizer spreaders which axis is placed inclined, reliably provides performance of technological process at change of frequency of rotation of its disk from 600 to 1000 rpm and changing the angle of installation of the disk to the horizon from 0o to 30o.
For all studied kinematic modes of operation of the new working body, the effective scattering range of mineral fertilizers and the distance from it to the tray with the maximum share of the mass of sown fertilizer increase most rapidly with increasing disk angle to the horizontal plane from 0o to 10o, and least when changing the angle within 20o - 30o.
The best indicators of fertilizer application both in terms of working width of capture and in terms of uneven application of fertilizers are provided at the angle of inclination of the disk of the new working body to the horizontal plane within 25o-30o.

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"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
