Abstract
A seeding apparatus may include a control unit to meter a predetermined amount of seed at desired intervals of time, distance, or the like. For instance, in one embodiment a tractor-towable seeder may include a trailing wheel, a sensor which detects the radial or circumferential travel of the wheel, and a control unit which receives the sensor input and triggers the release of seeds at the desired intervals. The control unit may take a variety of forms, including but not limited to a programmable logic controller or a low-voltage relay and distribution system. Suitable sensors may be selected based on the desired metering apparatus and control device.
