DESCRIPTION
UNE CEN/TS 17768:2022
This document specifies the procedure for the digestion of different organic fertilizers and organo-mineral fertilizers with aqua regia to enable a subsequent determination of elements. The extracts are suitable for analysis using FprCEN/TS 17770 and FprCEN/TS 17769. NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results.
