Abstract:
1. A row unit for precision sowing of seeds to obtain a predetermined number of plants per unit of length, comprising: a seed distribution device adapted to feed single seeds from a seed hopper; a seed discharging tube adapted to feed the seed by an excess air pressure from the seed distribution device to a seed outlet, the seed being forced throughout the seed discharging tube by the excess air pressure; a seed furrow opener, comprising two sowing discs arranged at an angle relative to each other; and a resilient press surface for pressing the seed into the soil; wherein the press surface is configured such that a direction of flow of the seeds at the seed outlet intersects or is substantially tangent to at least a portion of the press surface; and the seed outlet is located between the sowing discs and, as seen in the transverse direction, entirely inside the periphery of at least one of the sowing discs.
