Titel and Ted,
 
I've also used granite rock dust in CT as well as in the compost pile.
I was advised to spread
at least 10 lbs. of granite dust around fruit trees, from the trunk to
beyond the drip line. The dust or flour is very fine.
I also have access to basalt rock dust which is just as fine. I believe
what they said it's 200 mesh. The quarries nearby consider their rock
dust to be waste material. I mentioned in earlier posts that I also use
Azomite. Are you both using granite dusts exclusively or do you use
other rock material? Do you recognize any paramagnetic properties in
the dusts?

Rock dust -- well I should clarify that it isn't just rock dust but
granite -- has been known for quite some time to be a beneficial
addition to compost. I have used it in both compost and in tea. All
the tea I spray in the vinyards uses about 1/4 cup per 35G. I say about
because while the measure is fairly accurate it isn't exact. I use
pulverized granite. It is gray in color. Individual particle size is
very small but I wouldn't classify it as a powder like talc. It's more
like a sandy loam with some pebble size chunks that I have to crush
before use. I have been using it in my tea for the last 2 years for
certain applications. For others, I don't use it at all. It is in all
my compost but the compost designed for California Coastal native
plants. I don't use a lot. But even using this rock dust I have not
witnessed what you report. Therefore, I remain a doubter.
