Scope
This document specifies a method for the determination of exchangeable acidity in barium chloride extracts of soil samples obtained according to PS 3060.
The procedure described herein mainly concerns the determination of total exchangeable acidity by means of a fixed pH end point titration.
Two additional and optional procedures are given, describing respectively, determinations of free H+ acidity and aluminium in the extracts.
This document is applicable to all types of air dry soil samples.
