pots and fertilizer all in one!

Interesting idea, I just wish they would provide some information of an ingredient list for the pots. I assume they are just manure, but they don't tell us whether this is the fact or not.

OH saw these on Dirty Jobs. Not sure if its the same company or not. They basically take the manure, sterilize it and then form it into the pots.
I don't think there is any additive or anything, nothing non-organic anyway. It's been a while since I saw the show but thought it pretty interesting way to use up all the tons of cow manure a dairy farm would have!
