I hate to be funny, but there must be a cheap source out there
someplace.  I know farmers in Illinois who dump up to four
tons of calcium carbonate per acre on their fields.  It changes
the pH just enough to open up significant amounts of trace
elements.  So, it must be REALLY cheap if you buy in bulk.  :-)

I'm not sure where they get it, though.
