Beaver Muck as a completer fertilizer?

I met an old timer who lives by himself, totally isolated from society. After talking with him for a while and offering him a smoke, he really opens up and starts telling me about his homegrown and offers me some instead. Of course I did not want to be rude so I accepted the offering. Words alone cannot begin to explain the exceptional taste and high that later accompanied it. To make a long story short, this guy uses beaver shit and worm castings in varying degrees of decomposition (fresher on the bottom). And thats all he uses from start to finish except good old dirt from his spread. His plants were a picture of beauty. Anyone else heard of this, or better yet tried it?

Beaver muck is often low in N so I would add a little moose poop. Peace Jack
