I don't know how to judge according to that scale, but I would think it will depend on what you are growing?
During winter, I like to look through my state ag extention's publications. I came across ones intended for commercial agriculture (warnings in strong languages that the publications are not for home/residential gardening). They were interesting in that there were detailed pounds per rate for macro and some minerals and micro nutrients. And the amounts were specified for EACH CROP.
OT: They were for conventional --not for organic-- cultivation and the amount and frequency of fungal/herbicidal/pesticidal fumigation before planting, during growth, and prior to harvest were pretty scary to me.
BTW -- chemical nitrogen doesn't stay in the soil -- it out gasses and gets washed away.... Organic matter and microbes help to keep it locked in the soil for the plants to use.
