Abstract

The article describes the design and technological process of the fertilizecoulter, which ensures the placement of fertilizers in two layers simultaneously with the formation of ridges and ensures uniform distribution of fertilizers to a given depth with a ribbon width, presents the scheme of the chisel cultivator fertilize coulter and the scheme of the fertilizewide with a three-way divider, and also justifies the parameters of the fertilizecoulter for local application of mineral fertilizers. In addition, the results of theoretical and experimental studies on the justification of the technology of fertilization and the development of a combined machine and a universal chisel cultivator - fertilizer are presented. A formula is proposed for determining the depth of the stroke of the tuck coulter, a formula for determining the diameter of the outlet of the collecting part of the tuck guide and the length of the guiding part of the tuck guide, and regression levels are given that adequately describe the uneven distribution of the fertilizer flow along the cross section of the tuck guide. Recommendations are given on the norms and methods of fertilization, depending on soil conditions.
