Urine, as it comes from the source, is sterile. If it's not, that means you have a bladder infection. It's pretty much pure nitrogen fertilizer that has no beneficial microbes with it. Worm tea and compost tea are teeming with beneficial microbes, ready to compete with plant pathogens that are trying to get a toehold on your prize vegetables. If you douse your plant with fresh urine (properly diluted, of
course), that's going to give the plant a nitrogen
boost, but then it is still on its own to fight off microbial nasties that might be lurking. If you add your urine to worm or compost tea, then you have provided lots of good bacteria and other microbes that can squeeze out the pathogens.
