So your AA bar has knifes setup on 15 ft centers?

Why can you see where just one knife was plugged or two on a AA bar?

If you did skip passes with half rates for N here you would have huge yield difference between the two.  Maybe it would help one row over but not 15 ft. 

I really don't know how you think you can spread litter every other 15 ft and be totally fine with that.  Nitrogen is not the only thing that will make the grass streak.
