28% Sidress
My Personal Predictions for Plots
Before Harvest
•
•
•
•
•
•
•
Preplant would out perform Sidedress
nH3 would out perform 28%.
N Serve would make no difference.
Boron would make no difference.
No Idea what to expect on N RX.
OptRx would not works as well.
Higher Rates of N would produce more corn.
