Soil quality — Determination of pH

ISO 10390:2005 specifies an instrumental method for the routine determination of pH using a glass electrode in a 1:5 (volume fraction) suspension of soil in water (pH in H₂O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl₂).

ISO 10390:2005 is applicable to all types of air-dried soil samples, for example pretreated in accordance with ISO 11464.
