Whirly gig lawn spreader for half an acre seems easy? If you have heavy black soil maybe get by with 40 units. On half acre you are looking at roughly 50 lbs of urea. Or in a pinch two bags of lawn fertilizer (27-0-0).
I used to have a supplier for ammonium nitrate and that was my preferred method for top dressing.
If you have lighter soil may need more and split. I put 60 units on preplant here and I don’t think I will run out because of the drought. Another reason to not put it all on up front. Has to rain and if not, no amount of n will help. Will I have full production? Nope. Will it make harvestable ears? Probably.
Production acres here get between 120 and 160. (8ish t). 60 units will get you roughly 3-4 ish.
