Check the one where pumpkins is used - they test for various bacterias. As a matter of fact, urine (of a healthy person) is STERILE, you can even drink it directly - it's called urotherapy.

Maybe, if OP is interested, I can post more about urine fertilization. After all, if you find some complementary potassium source, it's a pretty cost effective way to grow stuff...
