The invention relates to agriculture and can be used to improve meadows and pastures.

The purpose of the invention is to reduce the energy intensity of the process of cutting the core and reducing damage to the sod.

Fig. 1 shows a working member for the subsoil introduction of liquid fertilizers, side view j in Fig. 2 - section A-L in Fig. 1.

The device for the subsoil application of liquid fertilizers on meadows and pastures contains frame 1, cylindrical ballast tank 2 with disk knives 3, distribution manifold 4 with feeding feeders 5 and flexible hose 6 connected to a hydrant (not shown), inlet rollers 7 and a transport wheel 8 with hydraulic cylinders 9. Fertilizing feeders 5 are connected to hydraulic cylinder 10. Circular knives 3 are placed on tank 2 and sharpened on a cone on the one hand (see figure 2), and on the other hand they have a spiral groove 11. Recessed It may have several turns. Between the recesses are protrusions 12, facing tops towards the axis of the disk knife.

A device for the subsoil application of liquid fertilizers on meadows and pastures works as follows.

In the working position, the cylindrical ballast tank 2 with circular blades 3 is filled with water to increase the depth of slot cutting.

Liquid fertilizers under pressure flow through the distribution manifold 4 to the fertilizer feeders 5 through flexible pshang 6. The disc knives 3, when rolling capacity 2, cut the soddy layer 13 and form a gap in the Soil to a predetermined depth.

When the circular knives 3 come out of the soil, the protrusions 12 raise the soddy layer 13 with their tops. Following the circular knives 3, the additional feeding feeders 5 enter the gaps under the action of the hydraulic cylinders 10 and feed liquid fertilizers into them, which moisten the soil in the gap area. The compactor roller 7 rolls up the raised soddy layer 13.
