Abstract

A system for dispensing agricultural products includes: a master controller, sets of agricultural product containers, meter devices, and secondary controllers. The meter devices are operatively connected to the product containers and configured to dispense products from the containers to rows in a field wherein each of the sets of containers is associated with a respective row in the field. The secondary controllers actuate the meter devices. Each secondary controller receives command data from the master controller and controls the meter devices for dispensing in response to the command data. Agricultural product from each product container is dispensed in accordance with operator defined instructions to the master controller. The instructions are capable of being provided to the master controller during the planting allowing the dispensing of individual containers to be controlled. In one embodiment the invention is a process for dispensing agricultural products at low application rates utilizing precision placement equipment.
