A single-grain sowing unit (1) for a precision seed drill is described, wherein the single-grain sowing unit (1) comprises a coulter carrier (2) with a crowd (3) attached thereto, a separating device (4), a catching roller (5) and one of the separating device (4). seed channel (6) leading to the catching roller (5). Characterized in that the tucking roller (5) and a lower end portion (6a) of the seed channel (6) on a relative to the coulter (2) movable catch roller carrier (7) are fixed, the catch roller (5) vertically from the coulter (3) decoupled be achieved and a continuous rolling contact of the fishing reel (5) with a furrow bottom. This causes a uniform storage of seed at high working speed.
