摘要：
FIELD: agriculture.SUBSTANCE: method includes ridge tillage, adding fertilisers to the ridges, and then planting the potatoes. Ridge tillage is made at a lower height relative to the traditional ones, and the potato is planted in the main horizon of the treated soil layer, increasing the depth of tubers implantation. The fertiliser distribution into the soil is carried out in such a way that their maximum content is at a depth of 25...30 cm, with a decrease in this content to the soil surface. Device for implementing the method contains a wedge-shaped post (5) located on the frame (1) with support wheels, a tube (20) mounted on its rear part, and a share (6) in its lower part, triangular ripping protrusions (9), the extension of which is made in the form of teeth, located on the surface of the shoe. The wedge-shaped post (5) is equipped with a bit (7), which together with shares (6), mounted on the shoe (8), forms a triangular arch growing in the direction of travel, inside of which the fertiliser dispenser (10) is installed under the fertiliser funnel (20) with the surface formed by rotation from the outside of circle sector. A hopper (2) for mineral fertilisers with a metering device (3) and a fan (4) are installed behind the wedge-shaped post (5) on the frame (1). In the lower part of the frame (1), two fertiliser blades (11) are installed parallel to each other, each of which passes through its hollow shaft (12) of vertical mill (13) and has a lateral cut in the lower rear in the direction of travel soil lowering part, in the oval hole of which fertiliser directing plates (14) are set at different levels and at the minimum depth at the top and the maximum depth below inside the knife. Disc ridgers (15) are mounted behind the fertiliser blades (11) on the frame (1).EFFECT: increasing the potato yield.2 cl, 5 dwgИзобретение относится к области сельскохозяйственного машиностроения, в частности к способу обработки почвы с одновременным внесением удобрений перед поса
