Appendix C - NH3 Application
Appendix C - NH3 Application
When using the NH3 mode review the settings below to ensure the Cal # and Density have been
entered correctly. The Cal # is located in PCM setup under Primary Sensor Tools. The Density
value is accessed from the ARM launcher page in Product Setup.
NH3 Application Cal#
For All NH3 applications the Cal # units should be entered in Pulses / Gallon. The Cal # units DO
NOT change even if the displayed units are in (lbs. of NH3 / acre) or (lbs. Actual N / acre).
Density for NH3 and Actual N
Density will determine the units of the applied and displayed rate (lbs of NH3 / acre or lbs of actual
N / acre) in real-time applications. If the operator wants to apply and display the rate in lbs of NH3
/ acre, the operator would enter a density of lbs of NH3 / gal. If the operator wants to apply and dis-
play the rate in lbs of Actual N / acre, the operator would enter a density of lbs of Actual N / gal.
NOTE: Temperature affects the Density. Use the chart below to locate the correct value (Figure
1-1). Use the temperature or tank pressure column to determine the correct density.
Example:
Cal # - pulses / gal
Operator wants to enter and display pounds of actual N / acre. If the temperature is 65
o
F, density
would be entered in Product Setup as 4.19 lbs of actual N / per gal.
NH3 is 82% Actual N by weight
1gal NH3 @ 60
o
F = 5.15lbs x .82 = 4.22lbs of Actual N / 1 gal of NH3
