If you want to use urine as a fertilizer it should be diluted and spread out.
But anyway, a quick Google search says urine ranges from 4 to 8 pH. Unless you're peeing in the same spot every day I highly doubt it would be much of a problem.
A family friend shared 2 problems she's been dealing with since moving into her house:
The ground is all clay so it's impossible to grow anything without bringing in a crapload of dirt
The septic has an issue and has to be pumped every 3 weeks
I pointed out that clearly they need to be using the septic to fertilize the flower beds to solve both problems but for some reason she didn't like that idea...
That's a damn good question that I do not have an answer to. I don't speak with this person at all, and this was the first time my wife had spoken to them in years so we may never know
