Rocky Comfort, MO | When you say units, to me that is Actual N. One unit of N is one unit of actual N. If someone says they are broadcasting with a spreader set on 300 lbs/acre and they are spreading Ammonium Nitrate they are actually putting down 102 actual units of Nitrogen. As far is solution, 32% Uan weighs 11.06 lbs per gallon. You get 3.54 Units of Actual N out of that one gallon that is 11.06 pounds. So you actually are getting .32 lbs of N per pound of the solution. As far as sources, Ammonium Nitrate is 34 Units of N per 100 pounds of dry product. So one pound of granular dry product yields you .34 lbs of Actual N. Is this what you are asking?
Edit: To get one unit of N out of ammonium nitrate you would have to put down 2.94 pounds of granular product
To get one unit of N out of 32% solution you would have to put down 3.125 pounds of product or .2825 gallons
