Usng liquid urine as free fertiliser

I notice that Liquid Gold is currently available on Amazon UK for less than £4 including postage.

It's an easy, enjoyable read with amusing notes on the uses of urine throughout history.  It's also very reassuring if you want to use urine on your garden and want to know if it is safe/effective.  The key point is to dilute it, so that it isn't too strong for your plants.

(If anyone wants to know, I pee into an old jug and then pour it into plastic milk bottles for storage and carrying to the allotment.)
