1. A system for controlling seed spacing in a field comprising:
(a) a seed metering device constructed and arranged to singulate seed at an independently controllable singulation rate;
(b) a seed delivery channel comprising a proximal opening at a proximal end in communication with the seed metering device and a distal opening at a distal end;
(c) a seed spacing device disposed adjacent to the distal end of the seed delivery channel, the seed spacing device comprising a seed ejection wheel rotatably disposed therein; and
(d) a seed ejection wheel actuator operably coupled to the seed ejection wheel, the seed ejection wheel actuator constructed and arranged to independently control starting, stopping, and rotational speed of the seed ejection wheel.
