Re: Grit; granite vs. limestone

And when I lived in the central valley of California, grit was crushed oyster shell. I think we have a common name problem here. Since it's made for chicken's craws, you probably make it out of what you have that's cheaper than the other stuff you have.

Chicken grit- isn't that a somewhere between crushed/chunk type
limestone? Doesn't that change the ph of the soil? Would there be some
concern for really messing with the soil and having worse problems, or
then having to adjust with some chemical of sort to change the ph back? Donna

Depends entirely where you live. If you're in the far midwest where there's
no granite within 1000 miles but is underlain by limestone, then grit is
limestone. If you're in the east where NC granite is easily available,
then you can find granite grit (like me).
