Illinois | I spread 125 pounds of DAP and 125 pounds of potash ahead of my soybeans for the 2016 crop. This year was the highest yeilds I have ever had. I spread heavier ahead of corn.
I assume you are doing this for yeild. Higher yeilds mean higher removal rates. If you want to apply some N do it as DAP or MAP. If you don't have higher yeilds then you still have the excess fertilizer for the next crop and can cut back rates accordingly.
Edit: as another poster said to see a response to the nitrogen fertilizer you would have to be in a higher yeild environment where that plant can utilize the N. What yeilds do you see normally? What is your crop rotation
