1 Scope
This document specifies a method for the determination of boron (B), cobalt (Co),
copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn) in organic fertilizers
and organo-mineral fertilizers extracts using inductively coupled plasma-atomic emission
spectrometry (ICP-AES).
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.
This method is applicable to water extracts prepared according to CEN/TS 17766. The method can be used for the determination of other elements, provided the user
has verified the applicability.
