Accordingly, the latter discharges fertilizer (2) onto an agricultural area (8) by means of rotating spreading discs (3), wherein the positions of feed surfaces (4) for the fertilizer (2) on the spreading discs (3) are set in dependence on desired ejection angles which are individually adapted for the spreading discs (3) in a compensatory manner on the basis of a wind (6) prevailing during discharge, in order to counteract a deviation, caused by the wind (6), of an actual transverse distribution of the fertilizer (2) from a desired transverse distribution. By virtue of the fact that the rotational speeds of the spreading discs (3) are also adapted in a compensatory manner in order to counteract a deviation, caused by the wind (6), of an actual casting distance of the fertilizer (2) from its desired casting distance, it is also possible to effectively compensate for undesired wind influence of headwind or trailing wind.

A sowing machine and a method for separating and spreading granular material, such as seed or the like, are described, where the material is supplied by way of conveying airflows from a central container to metering devices via conveying ducts respectively associated with them. Furthermore, the material supplied in the conveying ducts is separated from the respective conveying airflow and the resulting discharge airflows are supplied via discharge air ducts to the respectively associated metering devices which are thus pressurized. Furthermore, the metering chambers are pressurized by way of supply airflows via supply ducts respectively associated with the former. The material is separated in the metering chambers by way of separating disks. Due to the fact that the supply airflows and the discharge airflows are fed into the metering chambers separately from one another, the required pressure level in the separating devices that generate the discharge airflows and thereby also the pressure level in the granular material dispensed from the separating devices to the metering devices can be reduced. This improves the separating quality of the metering devices.
