This European Standard specifies a method for the determination of cobalt@ copper@ iron@ manganese and zinc in fertilizer extracts using flame atomic absorption spectrometry (FAAS). This method is applicable to water and aqua regia fertilizer extracts obtained 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 FAAS and it is not necessary to apply organic matter removal.
