The variation in pH was probably due to several factors including a release of H+ by [Ca.sup.2+], [K.sup.+], and [Ba.sup.2+] ions to the soil suspension, liquid junction potential effect, and salinity effect.
Added electrolytes minimised the liquid junction potential, reduced fluctuations in pH measurements with time, and decreased the salt effect (i.e.
