Scope

This standard specifies a method for the routine extraction of aqua regia soluble elements (as listed in Annex B) from soil improvers or growing media. Materials containing more than about 28% (m/m) organic matter will require treatment with additional nitric acid. With high solute concentrations in extract solutions, spectral interferences and background enhancement should be expected.
