So you assume because you have not "observed" growth that N is not being utilized by the plant.

I expect that cool season grasses are able to continue to extract nutrients from the soil well after the first frost, but I suspect there is a soil temperature cut-off point for doing so... In fact I wouldn't be surprised that the 2weeks of 'response time' + about 4 weeks of active growing that 1 pound/k of N gets used up during September and another 1/2 pound/k applied on Oct. 1st might also get used up, in spite of CenroWisco grinding to a halt...

And you have reached these conclusions how? Experimentation? "Observation"?

"Anyways", that information is available if you would bother to look for it. Instead all we get is more wild theories instead of accurate information.
