Detriot Lakes. MN,(cool season) well, let's say you have a K blue lawn. Mostly sun-low to moderate thatch. 4lbs N per year is recommended for best results.

A shade turf with creeping red fescue should top out at 2lbs N/1000.

Mixed variety lawns can vary with soil composites. Sandy soils can leach nutrients, so requirements can be higher. Clay soils can hold N-(lots of P)-K, so requirements can be lower.

I think your question was concerning total nutrients, not just N, so you need to do soil tests to determine P-K levels. Then, you can take into account other factors and apply accordingly.

Treat every lawn as an individual.

Good Luck.
