LSU Soil test results came in. What to add before laying sod?

New to this and looking for some help. Here’s my interpretation:
1. Since I’m sodding, I’ll follow the “establish” guidance.
2. Nitrogen - Each of the Nitrogen options come out to ~4.5 lb N per 1000. (I based this off of using the molar fraction of N within each of the compounds.)
3. Phosphate - about 1.5 lb P per 1000
4. Potassium- about 2.9 lb K per 1000

For simplicity sake, let’s say I’m doing 1000 sq ft of sodding.

Does this mean I should add the above quantities to my soil before I lay the sod?
…Or…
Should I lay the sod now, then later add NPK in small doses until I achieve these quantities?

TIA for any help on this.
