1 pound of Nitrogen per 1000 sq ft is -all- you need. Don't
try to re-write chemical lawncare with your Nitrogen fetish.

Wow, one pound, and I'm set for life! Or, as so many other things, did
you forget that time plays a factor?

Perhaps you could tell us what happens to the nitrogen demand of soil
year after year when it's not receiving said application.
