Abstract: The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The seed is rapid conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation and enable high planting speeds.
