Arrangement for fertilizing the soil

The invention relates to an arrangement for fertilizing the soil, in particular for fertilizing soil for beet cultivation, with a fertilizer coulter.

In the state of the art, arrangements for fertilizing the soil in various designs are known in which liquid fertilizer is introduced into the soil in which the seeds are located.

Especially for fertilizing soils in which beet seeds have been planted, it is advantageous to add liquid fertilizer to the beets at an early stage in order to increase yield.
25

The beet seed is spread in the form of so-called beet pills by seed drills, whereby the soil is specially prepared in order to plant the beet pills in such a way that they can grow productively.

-2-

For beet sowing, the seed drills are pulled across the field by a tractor.

The problem is that the repeated driving over the field with a tractor and a sprayer or fertiliser machine

undesirable soil compaction can occur, which reduces the growth and thus the yield of the crop. The targeted application of fertilizer to the soil after sowing is no longer possible, as the beet pellets are only at a very shallow depth below the soil surface.
10

The invention is based on the object of specifying an arrangement of the type mentioned at the outset, which makes it possible to introduce both seeds and fertilizer into the soil while avoiding repeated driving.
15

According to the invention, the object is achieved with a device which contains the features specified in claim 1.

Advantageous embodiments are specified in the subclaims.

The invention is explained in more detail below using an exemplary embodiment. The accompanying drawing shows

In the arrangement shown in Figures 1 and 2, the container 1 for liquid fertilizer is connected to the fertilizer coulter 2. In front of the fertilizer coulter 2 there is the cutting wheel 3, with which a 70 mm deep gap is cut into the soil so that the fertilizer can be dosed into the soil by the fertilizer coulter 2 at a depth of 40 mm below the surface.
The sowing unit 4 and a guide roller 5 are also attached to a frame connecting the arrangement.

From the plan view shown in Figure 2, it can be seen that the assembly consisting of cutting wheel 3 and fertilizer coulter 2 has an offset in the direction of movement, which in the example shown is 35 mm.

The arrangement according to the invention makes it possible to introduce liquid fertilizer into the soil in one operation during the beet sowing, so that the sowing unit 4, which follows the cutting wheel 3, places the seed in the freshly fertilized soil. It is particularly advantageous that the growing seedling can immediately utilize the fertilizer in the soil and the soil does not have to be driven over again during the important first growth phase.
