So all in all I wouldn't p*ss on the potato patch that you're growing in if I were you. (I also make the same case in reverse to sh*coin maximalists by the way - for the same reasons).
I'm no horticulturist, but isn't urine actually a good fertilizer? Hence, you would want to piss on your potato patch?
It depends. Pissing on grass kills it eventually. People's dogs pissing on their lawns can cause chaos.
Shitting on your potato patch is a completely different matter. Hence we get that smell wafting in through train windows while passing a freshly fertilised field.
Too much fertilizer always burns out plants.
