Definitions

• the invention relates to a seed drill for direct sowing and / or mulch sowing according to the preamble of patent claim 1.
• Such a seed drill is described, for example, in German Offenlegungsschrift 42 31 136.
• freely rotatable disks designed as disc coulters are arranged which cut through the material on the ground surface so that there are no blockages between the coulters. This disc coulter does not carry out any soil cultivation in the actual sense.
• direct sowing is carried out with chemical weed control.
• chemical weed control agents are very expensive, so this process is not economical, particularly in areas where low crop yields are expected.
• the invention has for its object to provide a seed drill and a method for direct sowing or mulch sowing, in which weed control takes place.
• the disks are arranged in at least two transverse rows, that the disks are movably arranged on the frame in an upright plane and inclined to the vertical and inclined to a straight line running in the direction of travel.
• a very flat tillage can be carried out by means of these tillage elements, which act as a kind of disc harrow.
• Mechanical weed control is achieved by means of the disc harrow. Furthermore, it is possible to spread fertilizer on the soil surface in a wide distribution before the work on the soil cultivation with the disc harrow by means of a preceding work step using a fertilizer spreader. This fertilizer is then mixed through the disc harrow into the top layer of soil. This makes it possible to reduce the amount of fertilizer to be spread with the sowing process to such an extent that there is no risk of the seed being burned by the fertilizer, so that seed and fertilizer can be introduced into the soil through the seed coulters.
• the discs are adjusted with respect to the disc coulters so that they penetrate the soil to the same or less depth than the coulters, so that the seeds are attached to a solid layer of soil has water-bearing layer, can be deposited.
• a support roller or support wheels is arranged behind the disks, that the disks are arranged on a support frame, that the support frame is articulated in height relative to the frame, that the support roller or support wheels are attached to the support frame is height adjustable to adjust the depth of engagement of the discs in the ground.
• An advantageous setting of the support roller is achieved in that adjustment means are arranged between the support roller or support wheels and the support frame.
• the discs are set and guided at such a working depth via the support roller or support wheels that the coulters penetrate deeper than the discs in the ground.
• the discs are set and guided over the support rollers at a working depth such that the discs penetrate the soil to the same or less depth than the coulters.
• the seed drill for direct or mulch sowing can be used according to a method according to claim 6.
• a combined tillage of our seed drill can be provided, in which the two operations are carried out simultaneously.
• the method according to the invention makes it possible for a work step preceding the tillage operation to be spread over the soil surface in a broad distribution by means of a fertilizer spreader, and for the fertilizer to be mixed into the upper soil layer in the tillage work step.
• the fertilizer application can be divided so that only a small amount of fertilizer can then be introduced into the soil with the seed during the sowing process.
• the fertilizer can then to the extent that for the introduction via the coulters, that seed and fertilizer can be introduced together, since the fertilizer concentration has dropped below the so-called combustion mark. This means that the fertilizer does not burn the seed, so that the seed and fertilizer can be deposited in the soil through the coulters.
