Probably almost nothing. Usually the burn is from dusty urea, not because of tall corn. I topdressed corn that was knee high 2 years ago and over waist high last year (windy everyday and no rain pushed me out 2 weeks) and I didn’t see any differences in leaf burn. Also no measurable differences between fall nh3 or spring urea
