[Digestion] vermiculture of digested solids

[bennett at frognet.net]

Not to answer this, but to expand a bit.....
Is there documentation backed by laboratory research that tells the
"fertilizer values" of the digested solid wastes resulting from methane
production?  Would the vermiculture add to those nutrient values?
Thanks.
