This Standard specifies a method for the determination of pH in a 1 M KCl soil suspension and where required titratable actual acidity (TAA) in acid sulfate soil. NOTES:1 The TAA measurement does not quantitatively recover retained acidity held in iron and aluminium hydroxy-sulfate minerals, such as jarosite, KFe3(SO4)2(OH)6 and similar minerals. Methods to determine the retained acidity are given in AS 4969.6 and AS 4969.11.2 The suspension from this method can be analysed subsequently to determine KCl extractable sulfur, calcium and magnesium (AS 4969.4).
