Checking Planting Rate
Singulated seed charts are based on cleaned and sized
seed singulated with the recommended disk. Extreme
seed size variations, foreign material and tire pressure
can affect the planting rate.
Any material difference between chart and field rates
implies a mechanical malfunction, a planter setup error,
unsuitable planting conditions (such as excessive tire
slippage) or extremely worn planter components. You
can verify your setup and planter performance by
measuring seed placement and spacing over a relatively
short distance.
1. Determine the sample distance to check. Find your
row spacing in the table below
2. Note the number of rows to sample. Adjust the
planting depth to a shallow setting on one or two
outside rows (per table). Tie up the press wheel arms
with wire or bungee to prevent furrow closure.
3. For populations above 100 000 seeds/acre, use a
sample size of 1/1000th acre.
For populations below 100 000 seeds/acre, use a
sample size of 1/200th acre.
4. Configure the planter for the chart rate, either using
the chart settings for sprockets, or, with hydraulic
drive, selecting the rate on the seed monitor.
5. Plant at the desired planting speed for slightly more
than the computed sample run length.
6. Measure off the sample distance, balanced in
between where seeding started and stopped.
7. Count the number of seeds over the distance
measured. Also note the consistency of the seed
spacing.
8. Compute the rate for a full acre or hectare.
For a 1/1000th sample, multiply the counted seeds
by 1000.
For a 1/200th sample, multiply the counted seeds by
200.
9. If the field and chart rates vary by more than a few
percent, re-check planter setup, including meter disk
or cell count, air system, tire size, tire pressures,
sprocket or hydraulic drive setup, chain slack, etc. If
seed spacing is irregular, this suggests a seed
delivery problem, and not a rate setup problem.
10. While planting, pay attention to the seed monitor. In
addition to confirming the single-row furrow check, it
will also provide field rate data on all the other rows,
and alert you to any irregularities or stoppages.
