As for options for acidification, aluminum sulfate is pretty cheap, ammonium sulfate can be used as an acidic fertilizer, but like the earlier post said sulfuric acid (battery acid) will do. Just be careful--add acid to water (not the other way around or it can explode --more or less). It gets very hot when mixed, but I would mix it with water and pour it on the soil. I would start with just a few ounces is 5 gal of water and see how much that changes the pH.

It looks like I might be able to get the most out of my money by using aluminum sulfate since I can get for under a dollar per pound. Sulfuric acid looks extremely expensive so I'm not sure if is concentrated enough to be worth it.
Would an item like this look good?
Aluminum Sulfate 50 lb Low Iron - eBay (item 380013335133 end time Jan-21-10 14:43:56 PST)
I think I might need 3 applications per year of about 3lbs per square yard so I might need a 90lbs of it every year if my blueberry patch is 10 square yards.
