<p>ISO 14869-2:2002 specifies a method for the dissolution of total contents for the following elements in soils:</p>
<p>Na, K, Mg, Ca, Ti, Mn, Fe, Al, Si</p>
<p>This list is not exhaustive, and other elements are applicable for determination provided:</p>
<ul><li>they are not lost during the fusion process,</li><li><i> w</i> > (3<i>d</i> · <i>V</i>/<i>m</i>).</li></ul>
<p>where</p>
<p><i>w</i> is the mass content of the element, expressed in milligrams per kilogram soil,</p>
<p><i>d</i> is the detection limit, in milligrams per litre, for the element and analytical method considered,</p>
<p>3 is a conventional factor,</p>
<p><i>V</i> is the adjusted volume, in litres, of the final solution containing the dissolved sample, and </p>
<p><i>m</i> is the mass of the test portion, in kilograms,</p>
