Improving the efficiency of sowing winter crops with the modernization of the coulter for the application of mineral fertilizers

In the thesis, the modernization of the SZS-2.8 seeder was carried out. A new working body for the application of mineral fertilizers has been developed and calculated. The working body allows you to apply fertilizers simultaneously with sowing. The work was done on 65 pages of typewritten text and on 7 sheets of A1 drawings.
