Right, Larry, I've used a number of sources for dusts and fines including a quarry in the northwest that produced a super-fine material that worked very fast. Even the coarser material is effective but takes a little longer for results to show up. I urge those interested to ask for details from each particular regional quarry as they are required to have their material tested for heavy metals and should be able to provide a detailed assay of mineral components.

Pure environmentally clean finely ground rock dusts can be had free for the hauling from nearly all rock quarrries - this material is nearly as valuable as rock phosphate and greensand and adds significantly to the flavor and nutritional quality of crops.
