Scott,

When planting single (not twin) rows on Pluribus strips we have many customers putting down 50-70 units of N using our banding liquid tube and planting shortly thereafter.

The banding tubes place the fertilizer behind one or both of the rear coulters. With the banding tubes the fertilizer is NOT mixed in through the entire strip but in a band that ends up about 3x3 or 4x4 from the seed if the seed is centered on the strip.

However when planting twin rows onto Pluribus strips, if you use the banding tubes, even two of them per row, you are planting corn directly on top of a lot of hot N.

That is background info. In your particular plan for using the center tube and planting twin rows maybe the next day, I am still afraid there is a high probability of seed burn with 70 units of N even mixed in.

I think of the center tube as our "10-34-0" (or equivalent) tube. The center tube lets you put down more starter than you can in furrow and is typically used to apply 12-18 gal/a of 10-34-0  and to get the liquid off of the planter.

IF you have good moisture and can wait 4 to 7 days between stripping and planting your plan has a high probability of working.

Otherwise I would put a mix of your P, S and maybe 30 units of N through the center tube, forget the P in furrow on the planter (you will have plenty around the seed in the strip). While you could put the rest of your N down through the 2x2 setup on the planter I would avoid this especially with sweet corn and come back and side dress the rest.

I have not had good luck with broadcast urea at all unless you have irrigation to water it in as soon as you leave the field.

Getting the HD 2x2 off of the planter will do two things for you: speed planting (timely planting is the cheapest way to increase yields). And also get the heavy and variable weight off of the planter which can dramatically affect planter performance for fert tanks full to fert tanks empty.

I vote for side dressing the rest of your N between every pair of rows. every other row side dressing does not work on twin rows.

Or leave 4-7 days and do your original plan. Or just plant single rows and use our banding (not the centered one) tubes on your Pluribus for your original plan.

side dressed N is much more effective placed between the rows and covered.  However, I am not personally familiar with trying to side dress twin rows and if it is possible without causing much damage to the stand. Maybe someone else here has side dressed twin rows and can comment.

I also forget do not recall from your earlier posts whether or not you irrigate.

all in all jmho.
