ABSTRACT:
The present invention concerns a process and apparatus for sowing seeds in so-called precision sowing and a distributor for practicing such a process. The distributors comprise, for each furrow, a ploughshare 4 opening the furrow, a pneumatic transport channel 6 for seeds abutting opposite the furrow 8 and a setting wheel 1 sinking the seeds distributed in the furrow. The seed is, at the outlet of the pneumatic transport channel of the distributor, projected toward the apex D of the dihedral formed by the forward peripheral surface of the setting wheel and the bottom of the furrow.
