Rock Dust

[codger]

has anyone used rock dust as a suppliment for their garden. I hard about it ona radio show and it sounded troo good to be true you know what that means so I thought id ask. thanks

I assume they were talking about Rock Phosphate, Greensand, and Granite Meal ?
If so, all of those can be beneficial soil amendments; and good organic sources of nutrients (Phosphorus and Potassium).

lots of rock dust are great for the soil,if paying for some id look for azomite or glacial rock dust. but lots of rock powders and dust can be found locally and cheaper then you think. I'm sure HG will shime in.

ive been collecting river sand/silt free from near by as well as decomposing rocks. will be throwing in garden and they work very well in compost and worm bins.

Do large stores sell rock dust?

Well, they may, but that seem rather unlikely. I'd go to a garden center for that.

Also, isn't dolomite another form of "rock dust"?

check your local rock quarry or rock distributor. I get it free now, and I used to get it for 4$ a ton back at my old house. best to get as many different rocks as possible. and ask for the finest mesh possible( usually thats the stuff they don't want)

What we know as "lime" is one form of rock dust. Also, I've heard of dolomite lime, so dolomite is probably one form of lime.

None of the garden centers around me sells it neither small nor big. I called stone quarry, but they didn't want to bother giving it to me, they said maintenance guys take care of it. Do you just go there and ask them to put it in your bag?

I guess I will have to buy it online.
