This European Standard specifies a method for the determination of boron@ cobalt@ copper@ iron@ manganese@ molybdenum and zinc in fertilizer extracts using inductively coupled plasma-atomic emission spectrometry (ICP-AES). This method is applicable to water and aqua regia fertilizer extracts prepared according to EN 16962 and/or EN 16964. NOTE In most cases@ the presence of small quantities of organic matter will not affect determinations by ICPAES and it is not necessary to apply organic matter removal.
