FIELD: agricultural engineering, in particular, meadows and pastures improvement equipment. ^ SUBSTANCE: combined sod unit has working tools with spring-loaded section composed of two disks for forming vertical walls of strips. Disks are spaced from one another by distance equal to width of strip under cultivation process of rotavating working tools of sod drill and are offset with respect to one another in direction of advancement of unit by distance at least equal to radius of disk. Slitters-stone removers are located in front of spring-loaded sections of working tools along mid portion of strip. Fertilizers are fixed for axial displacement on slitters-stone removers. ^ EFFECT: increased yield of seed grasses through increased quality of sod cultivation by means of rotavating working tools, high-quality application of fertilizers and improvement of water-air mode of soil. ^ 2 cl, 5 dwg |
