There's plenty on the nets about this, but here's one:
https://www.scientificamerican.com/article/human-urine-is-an-effective-fertilizer/ "Urine is chock full of nitrogen, potassium and phosphorus, which are the nutrients plants need to thrive—and the main ingredients in common mineral fertilizers. There is, of course, a steady supply of this man-made plant food: an adult on a typical Western diet urinates about 500 liters a year, enough to fill three standard bathtubs. And despite the gross-out potential, urine is practically sterile when it leaves the body, Heinonen-Tanski pointed out. Unlike feces, which can carry bacteria like salmonella and E. coli, urine poses no health risks—astronauts on the International Space Station even drink the stuff—after it's purified."
This article in Modern Farmer is fun:

The label is actually a Tanglefoot band to keep ants/scales away.
The plant lost all its leaves but is finally starting to push some new ones. I'm keeping it out of heavy rains and fertilizing more often, with fingers crossed.
