Planting Rate Overview
The information in this section covers important setup
and checking information that applies to the Air-Pro
®
meter in singulated planting.
Singulated Rate Setting Summary
1.
For your crop, determine your intended population, in
seeds/hectare. If you know only the seed spacing or
population in kg/ha, consult the conversion formula
below.
2.
For your crop, population and desired field speed,
select the correct seed disk:
“Air-Pro
Meter Disk Selection” on page 4
3.
Set meter rate (page 11).
4.
For staggered twin row, time row pairs using:
“Sprocket Indexing (Stagger)” on page 24
5.
Set initial seed inlet shutter per seed rate chart.
6.
Set initial meter pressurization per page 6, 7.
7.
Verify your planting rate per the instructions at:
“Checking Planting Rate” on page 8. If the results
are consistent with your setup, plant the crop.
Population Reference Information
Seeds per Unit
If only population weight (kilograms/hectare) is known,
obtain the population count by multiplying the population
weight by the “Kernels per kg” value from the seed
container.
Seed Spacing
If only seed spacing is known, use the seed rate chart
(pages 14 to 23) to determine population.

Example: Corn
Target rate:
21.3 kg/ha
Seed density:
3500 seeds/kg
Population:
= Rate x Density
= 21.3 x 3500, or:
