I'm not certified (yet) and not a market farmer (yet) but I intend to be 
both within a couple of years (certified when/if someone in KY becomes 
accredited, until then I'll operate under the $5,000 rule).

I currently use sifted compost - sifted through expanded steel mesh - 
which I sterilize by baking or setting atop the woodstove for a day. 
Eliot Coleman and others advise against sterilizing growing medium, but 
I find that I'm forever picking weed seedlings out of my flats/pots if I 
don't. I tried using bagged "organic humus" when I ran out of ready 
compost this year, and it was less than satisfactory.

Eliot Coleman has a recipe for soilblock medium in his "The New Organic 
Grower" which involves compost, greensand, and 2 or 3 other ingredients 
- if I can locate those ingredients locally (not likely, honestly) I'll 
be trying soilblocks next year.
