what is the measure of acidity and alkalinity in my soil? I live in zone 5, about 50 or 60 miles southeast of St. Louis, MO

One can not tell the pH of their soil by just the location they live in. The only way to determine the pH is to have a soil test done. You might be able to draw some very general ideas about pH in your area by talking to others who garden close by but if you need accurate informaion a soil test is the only way to get it.
