sodium in urine is detrimental to most cultivated vegetation

I was thinking the dog walk at my apts had a lot of dead grass spots.

[Alas Babylon!]

The reason dog pee kills grass is that it contains nitrogen. Nitrogen has the power to kill grass, as you’ll know all too well if you’ve ever over-fertilized your lawn. So, if you’ve been finding discolored, unsightly patches on your lawn, nitrates and other salts in your dog’s urine are the culprits.

Does human urine kill grass?

No, human urine does not kill grass if applied after proper dilution and in fewer amounts. It is the best alternative to mineral fertilizers for grass and garden plants.

however, if you pee directly into the grass, it will result in the form of yellow spots in the yard.

The best method to apply the urine is by dilution enough that plants or grass remain safer from the direct effect. The dilution will save the plants from drying and yellowing.
