Default Urine as fertiliser

Anyone else tried using pee as plant fertiliser?


I read on the Internet that a number of people are using human pee as
plant fertiliser with success. The main things I read were that pee must
be fresh (within 24 hours old) or it starts to break down - if smelly
then it is past its best for plants and fit only as compost accelerator.
The other thing was that it must be diluted to around 1/20 or it can
burn the plants.


While I can see the need for diluting it, I don't see why it has to be
fresh. Pee contains urea, among other things, which itself is a good
nitrogenous fertiliser. If kept for a few days, bacteria will break
down the urea to ammonia (think unflushed men's public toilets on a
hot summer day!), which is also a good fertiliser, although I suppose
it is more volatile that urea, so some of it may be lost to the air.
But not much, I wouldn't think, as it's very soluble in water.

I wonder how much medication passes through the body to come out in
the urine, Then to be taken up by the plants?
