Deykun V. Justification of the parameters of the working body for intrasoil insertion of mineral fertilizers.

The object of the research is the processes of grains transportation through the fertilizer guide and distribution of grain mineral fertilizers along the width of the working body gripper. The aim of the research lies within increasing the distribution uniformity of mineral fertilizers around the area during the application process of the intrasoil means of insertion. The theoretical investigations were conducted on the basis of the methods of theoretical and analytical mechanics, the methods of variational calculus and analytical geometry. The experimental researches were conducted by using the designed original methodics of evaluation of the mineral fertilizers distribution uniformity along the width of the working body gripper and the widely-known methodics and methods of mathematical statistics and probability theory. The novelty of technical decisions is protected by 4 patents of Ukraine for inventions. The research model of the soil scarification fertilizer was tested on the agro field areas of Kirovohrad Research Station, on the agro field territories of LLC "Agrolan", Novomyrhorod region, Kirovohrad province and LLC "Stebne", Zvenyhorod region, Cherkasy province.
