I've written this somewhere on here before. We don't have a bathroom, so I pee in the garden all year. In the growing season, things get pretty crowded in the garden and there are only a few places with room to squat. So those few places get peed on a lot. I move around,but often I'll pee in the same spot for a couple days in a row.
It's possible my chickpeas didn't like it, but even the ones growing in spots I didn't pee weren't great that year. Other than that, I've noticed no problems with direct application.
Oh, and we get little to no rain for two or three months in the summer. I also don't water my garden, so undiluted pee is all it's getting. I do drink enough water that my pee has little to no colour, though.
