Ant fertilizer applied to late in the season is mostly wasted. The grass cannot uptake that much nitrogen in that short of time.
Do you have a link you could paste to this particular research? I would like to see it as I'm always interested in new findings. When you throw out dates like October 1 and October 10 (yes, I know thikngs vary from year to year), what part of Wisconsin are you talking about as Northern Wisconsin has a much different growing season that the southern counties.
