Machine for the discharge of seed and fertilizers, with at least two supply containers which are equipped with outflow orifices and to each of which are connected a metering device and pipelines opening into seed coulters, the metering device of the supply container intended for the seed having a number of conveying wheels which consist of a combination of a normal-sowing wheel provided with larger teeth and of a fine-sowing wheel equipped with smaller teeth, each normal-sowing wheel being arranged rotatably and each fine-sowing wheel fixedly in terms of rotation on the shaft of the metering device, and the fine-sowing wheel being connectable to the normal-sowing wheel by means of a coupling element lockable in two operating positions, and the metering device of the supply container intended for the fertilizers having a number of differently designed conveying wheels, the conveying wheels of the metering devices being driveable at an adjustable rotational speed via a variable gear and a path-dependent power source, and an agitator device being located in the supply container for seed. In order to develop further the machine for the discharge of seed and fertilizers, the fine-sowing wheels have two tooth rings of small teeth arranged next to one another and the conveying wheels for the fertilizers are designed as fertilizer sowing wheels.
