looking for imput on flying on urea onto standing corn around or just before tassle to help with grain fill. 

in theory, i'd like to

1. A. at planting apply 5 gallons approx of 10-34-0 (or comparible style starter) in furrow with zink, insecticide and.... 
    B. apply 5-10 gallons of 28 with some sulfer and boron 2x2 or 2x0 

2. side dress AA or 28 around 120 or so # of N depending on CoC or following beans

3. spray a foliar micro package around V5 with a fungicide. (over kill i'm sure, but don't want any deficiencies) (still searching for this package)

4.  Fly on about 20-40 pounds of urea (10-20 pounds of N) some time before tassle to help push it to the next level....

what should i expect to pay for a airial application of Urea? Have others used a program like this or similar with any success, or any failures i shoudl consider?

I will not be able to apply any of my liquid this year. I do not have liquid on my planter yet and will not till next year if i do....
