What about hair?  You can get bags of it at a barber shop.  It is 
100% protein, and is resistant to bacterial breakdown, but not 
entirely.  Suppose you had a soil-hair mix with plants rooted in it. 
Would it not be possible that bacteria could slowly decompose the 
keratin and release NH4 that could be taken up by the roots.  It is 
worth a try!
