Dear Karen,
Yes, worm juice is loaded with bacteria, it certainly can be used as a
bioactivator. I would use at least two cups of worm juice, and actually, I
think the best way to do this would be to invest in one of those hose-end
fertlizer sprayers--the kind that siphon fertilizer out of an attached
bottle. If you have enough worm juice to fill the whole bottle, fill it. If
you want to really turbo charge it, pour a tablespoon of blackstrap molasses
into the bottom of the bottle before you add the worm juice, and then stir
to make sure it dissolves. Set your sprayer to dilute the worm juice as
little as possible (probably about 20 parts water to one part worm juice) ,
then water your compost pile down with the sprayer until you completely
empty out the bottle.
If you don't have enough water pressure to do this, and need to use a
watering can, moisten the pile completely with plain water before watering
with diluted worm juice, say at about a ten to one dilution rate.
Happy composting!
Environmentally yours,
Ellen
