Variations in actual rates may be realized due to
differences in seed lots. For accurate rates with seeds
being used, follow the calibration instructions listed on the
Seed Chart inside the Seed Box Cover or refer to this
Manual. See Figure 3-21. The information listed in the
Seed Chart is subject to change without notice.
