1. An agricultural planting implement, comprising:
a plurality of row units, each of the row units comprising:
a seed meter, said seed meter including a housing and a seed disc therein, the housing having a seed side and a vacuum side, wherein the vacuum side applies a negative pressure to a full seed side of the seed disc;
a knock-off member on the vacuum side of the meter housing, the knock member including an extension that extends at least partially into a seed aperture of the seed disc to dislodge a seed held in the seed aperture by the negative pressure; and
a seed conveyor in communication with the seed meter to receive seeds from the seed meter, wherein the seed conveyor is adapted to move the seed towards an ejection location proximate to a bottom of a furrow and is adapted to eject the seed with substantially no horizontal velocity relative to the bottom of the furrow.
