In order to mutually position the successive seeds of the same row well, a furrow is broken open using a coulter (2) which has at least one downwardly converging profile piece (8) and the seeds (22) are thrown at the outlet of the channel (3) for the pneumatic transport in the direction of an impact point (15) of the periphery of the peripheral plane of a pressure roller such that they bounce into a converging furrow and are positioned there. |
