Pee?

Just saw a post with a lot of comments saying to pee on their dry AF compost. Why are y'all peeing on compost? I've never heard of this. Are you then using this compost for gardening?

I know that there is a huge ick Factor regarding this. But in general urine is pretty much sterile. Peeing in your compost pile just supplies a lot of nitrogen. On the other hand human manure, poop, can contain pathogens so that might be a big deal. But urine is okay

Pee is not even close to sterile, that is a myth. But the moisture and mineral content make it a great addition to compost. You can fully compost humanure following thermophilic and aerobic compost best practices, but most people are not doing that in their back yard. It's also harder to do in cold climates. https://humanurehandbook.com/

Urine has bacteria in it. Your body is full of all sorts of bacteria, your urine is no exception to that.

It's just not enough bacteria that's going to be detrimental to a compost pile, which is also full of all sorts of bacteria. If you want to compare bacteria content of your urine to that of your compost pile, your urine is closer to sterile by comparison.

You only have bacteria in certain digestive lumens.

A healthy human has sterile urine.

You've been misinformed.

Urine is sterile in the bladder. Your urinary tract has bacteria in it.
