Serious question: Urine as a nitrogen source for organic composting

UPDATE:
Here, for the record, is a picture of my ad hoc 'compost' bucket ...
where I put all kitchen food-related trash (eggshells, banana peels,
lettuce cores, chicken bones, fat cuttings, orange peels, stale bread,
etc.):

Notice the patented NPK 12:1:2 fertilizing formula I've been using,
thanks to all your advice!
So far I've been emptying this about once a week into a large wheeled
green compost bucket (which is half full and getting unwieldy).
The bottle of urine you see there is about a day's output from yours
truly:
* That's about ~1.5 liter / day / person
* Which is about 7.5 grams of Nitrogen per day
* And about 6 pounds of Nitrogen, 1 pound Phosphorous,& 2 pounds of
Potassium per year
I wonder what a comparison cost would be for equivalent store bought NPK
12:1:2 fertilizer containing 6 pounds of nitrogen?
It looks like apple juice or recycled beer. ^_^
