Abstract: In an example, a method to calibrate a research seed planter may include transferring seeds through the research seed planter. The method may also include automatically measuring, using the research seed planter and without requiring a user to make manual measurements, at least one of the following: an actual first seed elapsed time; an actual last seed elapsed time; or an actual seed spacing between seeds. The method may also include adjusting, based on the automatically measuring, a calibration parameter of the research seed planter that contributes to seed placement by the research seed planter.
