Near Intersection of I-35 & I-90 Southern Mn. | Use 720/10 = 72.0 for the meter cal. Since you have chosen NH3 as the product, the Ag Leader will perform the conversions from gallons to pounds for you. If you use the Raven NH3 meter cal divided by 10, the conversion would be done twice. The result would be that you would only apply about 1/4 of what you desire.
By default, the controlling product will assumed to be Pounds of Actual "N" desired. Since you indicate that you desire 140 Pounds of actual "N", simply enter 140 as the target rate. The Ag Leader takes care of the 82% conversion for you.
The numerical onscreen applied rate should hover around your target rate of 140 Pounds of Actual "N". The onscreen map will show the Pounds of NH3 applied in various colors as indicated by the map legend.
When your supplier weighs back your tanks, they will take the full weight minus the return weight which will be the number of Pounds of NH3 you have used. Multiply that value by .82 to convert to the pound of Actual "N" you have used from that tank. Divide that number by the number of acres shown on the Ag Leader. This will be the Actual applied rate. This should be close to the 140 Pounds of Actual "N" that you desire.
I haul our tanks back/forth to the supplier. I keep a log in the pickup. The log consists of the field, the tank number, the actual weights, the target rate and the actual applied rate. As we switch tanks, my operator tells me the number of acres that the tank I'm returning was used on. When I get to the supplier for another tank, they tell me the net weight used in Pounds of NH3. I do the math and make an entry in my log for each tank.
That way if there is some type of problem we catch it quite soon rather than blindly continuing to apply only to determine later that there was a problem. Last Spring, one of the tanks had been filled earlier and the full weight was obviously out of line. My log showed this very clearly and the supplier made an adjustment for the error.
