But - and there is always a but . . . .
Both bioavailable nitrogen and phosphorus, but WAY lots of salt (NaCL). After a while the salt builds up and there goes the plant. Just ask anyone who has a dog. Those dead yellow spots in the lawn are the result of too much salt all in one place.
Sadly, an urban myth (peeing on veggies). Now, if you want to discuss "night soil" on veggies, then that is a different discussion altogether. But that one is something that very few of us would consider.
