can I add urine to my vermicompost?

CelbriseSeptember 21, 2012

technically it's a regular compost bin in a 5gal bucket atm waiting for money to come in so i can buy my worms but i do have some worms/millipedes in the bin atm. although the bin is moist it won't stay moist forever i mean probably within like 2-3 weeks it will dry out.

i was wondering if i could add urine to the bin or will this kill off my worms/millipedes?

i know urine works well with compost as i use it on my outdoor pile it's been doing great adds nitrogen and waters it at the same time.

Urine also has salts. You do not want to add salt to the bin.

The urine will also breakdown into ammonia either killing the worms or driving them out of the bin. The best way to capture & utilize the nitrogen in urine is like you said in a separare compost heap. But if you plan on using that pre-compost material as worm bedding/feed there maybe an accumulation of salts so it would be best to cut that composted material with fresh bedding material (low in salt).
There's a great book by Thomas Jason Barrett on vermi-composting, it's the ONLY book that focuses on harnessing the earthworm for building soil, everything else focus on cultivating worms for the commercial bait industry.

Here is a link that might be useful: Barrett's Book
