Description

seeder

The invention relates to a seed drill and a method for applying seed and fertilizers with the seeder according to the preambles of claims 1 and 6.

Such a seeder and such a method for the application of seeds and fertilizers with a suitably equipped seed drill is described in DE 25 40 247 A1. In this sowing machine, fertilizer is first scattered to the soil surface in broad distribution. This happens here in the range of grooves pressed by packer rings into the ground. Subsequently, the fertilizer covered in the grooves is covered with soil by moving soil through successive coulters in creating seed furrows. By means of the coulters, the seed is deposited in the seed furrow. By following

Seed harrows are pushed into the seed furrow to cover the seed. Subsequently, the soil above the seed furrow is pressed by subsequent pressure rollers.

The problem here is that a large amount of fertilizer is placed in concentrated storage and in close proximity to the seed. Furthermore, a small amount of fertilizer is missing in the immediate vicinity of the seed as so-called starter fertilizer. In addition, additional packer rings must be present to create the furrow for the storage of the fertilizer in the soil. The invention is based on the object, in addition to a simple application of the fertilizer in larger quantities in a simple manner to start fertilizer in the field of seed in the ground.

This object is achieved in that are arranged on the coulters feeders for seeds and fertilizers for the simultaneous supply of seed and fertilizers.

As a result of this measure, simultaneously with the storage of the seed a small amount of fertilizer as so-called starter fertilizer to the seed in the Säfurche with filed. The fertilizer receives here very good starting conditions. For the further development of the seed is then in larger quantities on the

Soil surface deposited residual fertilizer available. In order to be able to advantageously apply the seed in the direct sowing process, it is provided that the seed coulters are designed as chisel coulters each having a tine.

To easily run the so-called starting fertilizer coulters and to be able to store in the ground, it is provided that the coulters each via the leads to the filing in the torn from the coulter in the soil seeding the seeds of the auszubringenden seed together with the Starting fertilizer serving fertilizers are fed. In order to guide the coulters in a simple manner in the penetration depth in the ground and to avoid excessive ground movement, it is provided that the

trailing depth guide means as two spaced from each other

arranged, freely rotatably mounted and facing each other disc-like side surfaces having depth guide rollers are formed. Furthermore, such arranged depth guide means are adapted to the on the

Soil surface in wide distribution deposited fertilizer near the surface in the area of the seed furrow into the soil.

In a further embodiment of the invention it is provided that the

Fertilizer application devices are arranged in the region of the trailing depth guide means. As a result of this measure, the fertilizer application devices are arranged in an area in which the soil is in motion and the depth control means can advantageously incorporate the fertilizer near the surface in the soil.

By incorporating the fertilizer in the soil or mixing with soil parts, it is ensured that the ingredients of the fertilizer do not evaporate. Furthermore, a method for applying seed and fertilizers is provided with the prescribed sowing machine. This method is characterized in that the supplied fertilizers are distributed in broad distribution in front of the coulters on the soil surface by the arranged on the frame of the seeder before the coulters fertilizer applicators, that distributed on the soil surface fertilizer through the subsequent coulters at least partially with the bottom parts the upper soil layer are mixed by the seed furrows tearing into the soil coulters, then that the seeds of the seeds are introduced with the fertilizer serving as fertilizer fertilizer in the seed furrow and stored there that by creating the seed furrow from this through the respective coulter Ground raised by the disc-like side surfaces of the

Depth control roles caught and at least partially reflected in the seed furrow for covering the seed grains and fertilizers stored in the seed furrow.

Thus, seed and fertilizer are applied in an optimized manner, so that the seed receives optimal start and growth conditions even under difficult conditions.

According to the method, an advantageous placement of the fertilizer deposited on the soil surface in a wide distribution can be achieved by mixing the soil parts with the fertilizer scattered on the soil surface by collecting and repelling the soil parts through the depth guide rollers.

The above-mentioned advantageous placement of the fertilizer deposited on the soil surface in a wide distribution can likewise be achieved by mixing the soil parts with the fertilizer scattered on the soil surface through the depth guide rollers.
