Title: Re: [Market-farming] Application Rates for Poor Soil
One of many references to cadmium and tires and food on the web (This one from the Universtity of California) http://celosangeles.ucdavis.edu/envhort/trace_elements.html

Cadmium

 Cadmium is a contaminant of many manufactured products containing zinc. Any zinc plating or galvanizing operations and galvanized metal containers sometimes used in horticulture and gardening operations are potential sources of cadmium. Zinc is also used in the vulcanization process in tire manufacturing. As tires wear, they give off minute, dust-like rubber particles containing cadmium that easily disperse and accumulate in soils and on plants.
