Somewhat newly laid St. Aug (maintenance question for board experts)

Board Experts,
Should I fertilize newly laid St. Aug (laid middle of July) and existing St. Aug now or not?
Also, if not, when should i apply pre-emergent and what specific pre-emergent to existing St. Aug?
Finally, don’t apply pre-emergent to newly laid St. Aug, correct?
Below is my soil analysis from June 2022:

I would not fertilize with a nitrogen based fertlilizer this late in the year, as sod is generally pre-fertilized to begin with, but you could fertilize now with 0-0-60 potash (potassium) to strengthen the grass going into winter.
That is correct, do not apply pre-emergent to a newly sodded lawn as it is a root suppressant - that is clearly stated on pre-emergent label.
Because your sod was was laid in mid July, I think you should be OK to use a pre-emergent herbicide around mid-October.
Prodiamine or Dimension are two good lawn pre-emergent herbicides, available as spray or granular, your choice. Re-apply pre-emergent around mid-Feb. Start your normal lawn fertilization program in early to mid-April.

CrawDude,
When you say April, you recommend, based on soil sampling, that I choose one of the nitrogen products set forth in my soil sampling in April and then the 0-0-60 potash as well?

you can basically ignore the nitrogen fertilizer recommendations on the soil sample report. Use a moderate to high nitrogen fert (nitrogen being the first number in the XX-XX-XX format printed on the bag). Nitrogen content should be anywhere from 15-30, though I typically like to stay around 15-20 to reduce risk of burning the lawn. Some amount of slow release nitrogen is preferable as well. Try to find a fert that has approx 3-1-2 or 4-1-2 NPK ratio. Use 1lb of nitrogen (which is not equivalent to 1lb of fertilizer FYI) per 1000sq ft of lawn. What area are you in? If acadiana or BR area, people can give you specific fert recs from certain vendors.
Ignore the potash at this point, that was a fall-season suggestion to "winterize" the lawn in preparation for winter.

Thanks, Sir Saint. I am located in BR.
