Abstract

An assembly and a method for the precision drilling of seed grains use a drilling machine with at least one row unit which is assigned a drive set up for instigating delivery of a seed grain into a furrow, and a control system which is connected to a position-determining system, to a memory device for storing delivery positions of seed grains, to the drive of the row unit and to a seed material sensor for detecting the actual delivery position of the seed grains in the furrow. The control system controls the drive based on signals from the position-determining system, the memory device and the seed material sensor so that the seed grains are delivered successively at the delivery positions.
