Your soil pH should not change much unless you are doing something to change it. If you live in a limestone area you are never going to change it from 7.5 or 8. You cannot add enough sulfur to dissolve all the limestone for however many feet it is deep. Mine is about 1,000 feet deep, so it isn't changing.

Check out this site for some DIY remedies. I don't think litmus strips or hand held probes work very well. Generally they test the pH of the water in the soil.

I live in central Massachusetts. Logan Labs results showed I was at 5.8 in November of 2015. Applied quick acting lime at the bag rate twice in 2016. Just added Mag I cal today at the bag rate. Just wondering if I was making any headway in the getting to the 6.8 to 7.0 range.

Did you post the results of your Logan Labs test here in this forum? Usually the approach to fixing everything the lab shows would be in that topic. If you have not, then post it in a new topic with a subject indicating it is a soil test result.
