Rock dust is of course, inorganic. And since microbes consume the fine dust easily, they then discharge organically available plant food. The warmer the climate, the more microbes that are available to create plant food.

I think your correct UF...it may take some time. Even though they seem to grind it pretty fine. Fine enough to go through a sprayer.

Personally, I wouldn't use it. We need to know what's in it before we throw it into our little ecosystem.

Agrowinn-Minerals (Rock Dust) have an extraordinarily high level of minerals and trace elements (57 different trace elements) in well balanced quantities. (Contact us for a complete trace element list).

UF, you didn't ask for the list..?
A great researcher would never draw conclussions with out the facts..

There must be no barriers to freedom of inquiry ... There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. - Robert Oppenheimer, 1949
The surface area of the particle changes relevant to the radius by a power of 3. Bacteria require the surface area to be efficient at consuming the minerals. Assuming the dust is say 2mm vs. 0.1 micro meter the surface area would be off by a factor of 8,000,000,000,000 (and that's assuming a sphere). It might seem close, but it's not even close. Just imagine how long that would take if the decomposition rate of the mineral rock is a function of the surface area... JUST IMAGINE!

As far as asking for the list, there's no need. Given the limited number of elements on the periodic table, it can be logically deduced that there are several toxic elements included. Whether the concentration is low or not for 1 dosage, it will accumulate in the system. I still wouldn't do it! I can "show my work" if you want!
