Granite is supposed to be one of the best sources of micronutrients; 
Stone Mountain area in Georgia,
Lithonia, Ga. has a compsny supplying a "hybrid" granite dust - years 
(decades) ago they sold this product mixed with chicken manure.
Monument companies would be a good source though they would probably not 
have tons to give away.
At a dollar a pound, a large tandem dump truck load of Nitron's rock 
powder would cost $30,000.
