I have a worm quesion.
My garden soil is a loess, and essentially is pure 100% clay, originally wind deposited. I have a high organic matter content, but very low worm population. I read some where that in this type of soil there is no grit for the worm crops, and hence no worms. I read that by sprinkling and working granite sand in the soil the worms will begin to appear. Does this sound plausible? Also there is no granite around here and where would one get such an item?
