1. A seed orientation system, comprising:
a seed collector in which seed from a seed source is gathered;
a seed orientation coil assembly in seed communication with the seed collector, the seed orientation coil assembly defining a curved pathway therethrough toward a seed exit path;
a sub-furrow opener disposed adjacent to the seed exit path, the sub-furrow opener configured to form a wedge-shaped sub-furrow within a previously formed furrow in a soil surface;
an incoming air feed delivering pressurized air into the curved pathway, the pressurized air propelling the seed from the seed collector along the curved pathway and through the seed exit path into the wedge-shaped sub-furrow.
