The invention concerns a seeding and fertilizing machine whose feed rollers impacting the furrows have been provided with a coupling device 2 with which the feed rollers in question can be uncoupled from the rotational operation of a drive shaft 1'. To ensure that no unnecessary fertilizer or manure is left in the furrows, which would promote the growth of weeds, the machine has also been provided with a coupling device 12 at a point between the feed rollers provided with a coupling device for seed, with which coupling device 12 the fertilizer feed roller in question can be uncoupled from the rotational operation 1 of its drive shaft 1'. <IMAGE>
