This document specifies references to methods for the determination of the content of the following specific micronutrients in inorganic fertilizers:
— the total boron content;
— the total cobalt content;
— the total copper and zinc content;
— the total iron content;
— the total manganese content;
— total molybdenum content;
— the water-soluble boron content;
— the water-soluble cobalt content;
— the water-soluble copper content;
— the water-soluble iron content;
— the water-soluble manganese content;
— the water-soluble molybdenum content;
— the water-soluble zinc content;
— the sum of declared micronutrients in compound micronutrient fertilizers.
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply.
There is a possibility that the use of an analytical method specific to one of the components of the fertilizing product blend can give deviating results compared to other methods meant for the same analyte contained in another component due to analytical interferences by means of variances in the sample matrix.
