Hello everyone,

 

I want to get a dry fertilizer product that I can bag and hopefully sell.
I have been planning to take my liquid digestate and add sawdust or
something similar to dry it and then have the worms eat that.   I've read
somewhere that if I was to filter and dry the digestate I would lose a lot
of N with the water.  I know I would lower the Nitrogen percent by adding
the sawdust but would I gain by not losing the Nitrogen with the water?
Also seems I would improve the fertilizer by having worm casts and more
microorganisms from the worms gut.  

 

I'm about ready to actually start this but since the subject has come up
again I thought I should ask the list for comments.  It would be nice to
know before I start if I'm wasting my time.
