You would need something for them to eat like composted manure, sheep is good if you can get it. How big are your pots? I started with 4 worms in each of my 10 gal pots and had 20 plus in each before 6 months was up.
You would also need to add some minerals to that, like Basalt rock dust or glacial rock dust. I feel Gypsum is is better than dolomitic lime, as it also contains sulphur and wont change your soil PH no matter how much you use. Get yourself some Epsom salts as well for Magnesium. Kelp meal, if you can get it is very good minerals as well as K.
I have been doing no till for just over a year now. If you want to check out my thread its here.
