Purpose Applying standard soil analytical methods to novel soil materials, such as tailings or
soils with unusual properties, should be done with caution and with special consideration of
potential interferents and possible pretreatments. The aim of this study was to investigate the
effects of common variations in methods on calculated total moisture content, pH, and
electrical conductivity (EC) of saline alkaline soil materials. Materials and methods Bauxite
residue (an alkaline, saline–sodic Technosolic material) as well as two saline alkaline soils …

Purpose The aims of this study were to identify potential sources of error in common
methods for determination of amorphous oxide concentrations and carbonate
concentrations, as applied to a Technosolic material (bauxite residue), and where possible,
suggest improvements to the methods. Materials and methods An acid ammonium oxalate
(AAO) extraction was applied to fresh and weathered bauxite residues, at soil to solution
ratios varying from 1: 100 to 1: 800. Two methods for carbonate concentration were …
