Accurate measurement of soil pH is done by:

Electronic pH meter (pH meter):

It is a small device that looks like multimeter. We immerse the electrode appropriate for soil testing and in the monitor we can see the pH value accordingly. To successfully measure soil pH, follow the manufacturer’s instructions.

pH measuring tapes:

They are small disposable paper strips. Depending on the color change, we can find out the pH value in the soil. Always follow the manufacturer’s instructions, or send a soil sample to a dedicated to pH Measurement laboratory.
