A furrow opener of an air seed planter is equipped with a seed boot and seed positioner for planting one or more rows of seeds in soil. The seed boot has walls providing a passage for directing seeds into a furrow. The seed positioner attached to the seed boot channels seeds in one or more rows of seeds and covers the seeds with a substantially uniform layer of soil. The forward ground speed of the air seed planter and the velocity of the seeds carried by the flowing air reduce seed bounce due to the reverse drop of the seed boot.
