Nitrogen Requirements for Corn

Nitrogen requirements for corn range anywhere from 1.1 to 1.2 pounds of nitrogen per bushel of corn. One thing to keep in mind is that it is not as simple as taking a 150-bushel yield goal and multiplying that by 1.1 or 1.2 to figure out how much nitrogen you need to apply. You also need to take into account, based on soil tests, what residual nitrogen may be left in the field from the prior year’s crop. The peak nitrogen uptake in a corn crop usually starts from about the V10 stage on up to tassel.
