Abstract
An apparatus and method for controlled delivery of seeds between the seed meter of an agricultural planter to an open seed furrow. Seeds are received individually and in a sequence from a seed meter into a housing. The seeds are conveyed in sequence through the housing by a conveyor at a controlled speed to a location proximate the open furrow, then gently released into the open furrow as the agricultural planter moves forward. The controlled delivery of the seed to the furrow ensures more accurate seed placement within the furrow at the desired seed spacing, thereby improving crop yield potential.
