What's the most accurate way to measure soil pH
I have a pH meter and have been told there is a way to use these pH pens to measure soil pH accurately. Is this true? If so, what's the procedure?
I've been lead to believe that those analogue pH meters (the ones with a long pH probe you stick in the soil) are completely inaccurate and are basically useless. I'm not sure if this is right, but I'd love to find out.
I understand you can get chemical tests that use colour changes to give a pH indication, this might be the solution.
What do you guys think?
