I actually read somewhere a few years bak, that "Earth Juice" products were derived from human waste. I was never able to discount it nor verify it. So I simply made a mental note to NEVER....buy EJ...why dont they use human manuer on crops? mexico did on tomatoes several years back and shipped them north. food and drug had a bird; poop fit.
Though it seems an 'acceptable' practice in many countries, even on food crops.
Besides Nitrogen, Potassium, and Phosphorus, there are lots of other chemicals in Urine.
arsenic 0.137 mg/L
Arsenobetaine 0.069 mg/L
Dimethylarsinic acid 0.036 mg/L
selenium 0.059 mg/L
zinc 0.62 mg/L
sulfur
formaldehyde
salts such as sodium chloride
Urea
plant growth hormones such as auxins
other minerals...
organic matter
The salt in the urine may be a problem...I would also think that contents would vary, depending on diet. Meaning..I doubt that someone eating pizza Hut, Micky D's, Taco Hell, ect. and washing it down with sodas and/or beer would be the same quality as the vegetarian's urine.

This book points out there is actually more nutrients contained in a year's worth of urine, than contained in a year's worth of feces.
As compared to feces, Urine has the benefit of being relatively sterile, unless the person has an illness. Also antibiotics and excess hormones are excreted through the urine (makes you think about animal waste pollutants too, though composting, and soil life, do decompose these to some degree). We are all connected.
