Paragraph 2 FIELD OF APPLICATION

This procedure is applicable to analysing samples of fertilisers extracted by Methods 25a and 25b for which a declaration of total and/or water-soluble element is required.

Adaptations of this procedure for the various trace elements are detailed in the methods defined specifically for each element.

Note:

In most cases the presence of small quantities of organic matter will not affect determinations by atomic absorption spectrometry.
