we are conducting experiments on pH of different soils. How often do I need to measure the soil pH? Do I need to measure continuously 24 by 7 in 365 days? How often the pH of the soil will change?
Please look at the following below links which may help you in your analysis:

Depend on the soil, but generally soils have a good buffering capacity.
Moreover,

Therefore, small pH variation requires big variation of H+.
Other question, pH in water or pH in KCl? They measure different properties of the soil:

remember, pH = -log10 [H+]
Therefore, small pH variation requires big variation of H+.
