TAke your .38 N and divide by your N source to get final weight of product needed.
Example: you have 5-10-10 fertilizer on hand. .38/.05= 7.6 lbs of 5-10-10 fert needed for the season to supply the N needed by the crop. You have to then decide what percentage you will apply at plant out and when you will apply the remaining portion.
I'd apply half the needs at pre-plant. And supply the remaining needs on weekly basis through drip feed.
You could also use Calcium nitrate and maybe skip the gypsum. I'd have to run the numbers.
