Abstract
A precision air planter for plot planting includes a metering unit with separate seed systems which may be selectively activated to allow alternately planting various seed types from one plot to the next. A rotary encoder provides location information which is used by a microprocessor to calibrate the system, control seed planting and spacing, control plot length and spacing and record data related to the planted plots.
