The invention provides a seed metering mechanism and a method for controlling the seed metering mechanism. The seed metering mechanism includes a seed metering disc (10) that rotates to drop a plurality of seeds in succession. The rotational speed of the seed metering disc (10) between successive seed drops is varied to control the seed spacing independently of the forward velocity of the seeder (4) whilst maintaining zero ground speed effect when the seeds are dropped. The variation of the speed of the seed metering disc (10) can also be used to minimise the spacing gaps or voids on the ground caused by missing seeds from cells or holes of the metering disc (10).
