This Standard specifies a method for the determination of potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) in acid sulfate soil after the determination of pHKCl and TAA in AS 4969.2.

This Standard specifies a method for the determination of potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) in acid sulfate soil after the determination of pHKCl and TAA in AS 4969.2.NOTES:1 This extraction procedure recovers soluble and exchangeable sulfate, sulfate from gypsum, as well as some sulfate from aluminium hydroxy-sulfate compounds (such as basaluminite). Sulfate from jarosite and similar iron hydroxy-sulfate minerals is not significantly recovered. Methods to determine the residual sulfur held in these iron hydroxy-sulfate minerals are given in AS 4969.6 and AS 4969.11.2 This extraction procedure recovers soluble and exchangeable calcium and magnesium, and calcium from gypsum.3 The KCl extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) measurements can be used in combination with HCl extractable sulfur, calcium and magnesium (AS 4969.8) to determine the net acid-soluble sulfur, calcium and magnesium (AS 4969.11).
