Intensive and extensive crop cultivation technologies are leading to the depletion of agricultural land fertility, causing a gradual decline in grain productivity. Soil fertility can be increased using mineral fertilizer, however it is necessary to consider the diversity in terms of space and depth as well as environmental aspects. Therefore, this study aimed to develop new design solutions by manufacturing machines for the intra-soil tiered application of fertilizer. The necessity in the development of such agricultural machinery was justified as the main mass of the wheat root system usually forms gradually at different depths (6 to 24 cm depth) and by the insufficient migration ability of phosphorus available for plant nutrition. Consequently, a distributor for the deep-loosener fertilizer unit had been designed, and important parameters were theoretically justified. During the analysis, the distributor flap installation angle β = 25–27°, the pipe installation angle α1 = 47°, and pellet drop height h1 = 53 cm. The proposed chisel-type working body with the distributor provided placement of differentiated doses of one/two types of fertilizer simultaneously at 3 different depths, at 8–10 cm (3rd pipe), 16–18 cm (2nd), and 23–25 cm (1st). In this process, 1st as well as 2nd pipes were in pairs, and 3rd pipe was separately regulated irrespective of the total cultivation depth, which allowed its application for any soil-climatic zones with different humus horizons. Field experiments have shown that the fertilizer distribution unevenness through the pipes 1 as well as 2 varies between 9 and 13%.
