<p>A rotating disc has perforated seed pockets which pick up individual kernels of seed from a cavity of a planter housing. Bulk seed flows by gravity from a hopper to the cavity which is pressurized by a blower. As the disc rotates through the cavity, air flowing through the perforated pockets will move the seeds into the pockets and hold them there as the disc rotates to bring the seed carrying pockets into axially confronting relation with a flat sealing surface. The flat sealing surface holds the seed in the pockets as the disc rotates further to a position wherein the pockets are exposed to an open bottom area of the housing at which point the seeds are free to fall by gravity into the soil.</p>
