Quote: It's pretty smelly...they cook it up to kill any bugs, mix it with sawdust and sand, it's supposedly has rewards for being one of the "cleanest" biosludges around, but it's definitely not composted to completion. I mean, it's uniform and dark and if I hadn't read their website, I wouldn't know it was human. But it definitely has a hot, ammonia waste smell and I'd be afraid of it burning delicate plants. I got it for $5 bucks a yard and nearly free delivery, so it sure was a cheap way to fill in some major holes in the yard!
The smell disappates, doen't it? I've been in gardens where it was used, and I don't remember any disagreeable odor.
