Digital Soil Testers

Anyone lnow the accuracies of these? Generally just looking for lime requirements. We have 22 fields but they only make up about 7 acres(unfortunately all we have to work with). Could aave is some money if we used a digital meter to check lime requirements

By definition, pH is quite variable. It is the negative logarithm of the proton concentration. In other words, you're measuring a value that's one one millionth of a whole value. That would be a pH of 6. A $20 handheld device is probably not going to be as good as an analytical laboratory.

If it was me, I'd send about 3 tests to a real lab and just spitball it. It doesn't have to be perfect.
