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. Following this, potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) are determined.

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. Following this, potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) are determined. On a separate test portion, peroxide pH (pHOX), titratable peroxide acidity (TPA) and excess acid neutralizing capacity (ANCE) are determined following digestion with 30% hydrogen peroxide. Following this, peroxide sulfur (SP), calcium (CaP) and magnesium (MgP) are determined. On samples where jarosite is present, or pHKCl < 4.5, residual acid soluble sulfur (SRAS) is determined on the soil residue remaining after peroxide digestion.
