[Digestion] Digestate comparison to liquid worm castings

[Alexander Eaton]

Jim,

We have applied digestate from cows to the leading edge of the worm worm
bin (where fresh waste goes) and we have not seen worms die or a reduction
in their consumption.  This was with low doses.  We have never applied it
directly onto worms, but it does not surprise me that it would kill them or
have a negative effect.  We are trying to determine whether or not worms
will then destroy any pathogens or if the biol has a positive effect on the
quality of the worm castings.  We are two months in,
with preliminary results suggesting a reduction in pathogens, and nothing
definitive regarding quality based on high levels of fluctuation.

Best,

A
