This document specifies methods for the reduction and preparation of samples of fertilizers, liming
materials and inhibitors, in liquid and solid form, and sets out the requirements for sample preparation
reports. It also specifies methods for the preparation of test samples and test portions from laboratory
samples of product for subsequent chemical or physical analysis. It does not cover the preparation of
samples for certain physical tests which require test portions of more than 2 kg.
NOTE 1 The term product is used throughout the body of this document and is understood to include fertilizers,
liming materials and inhibitors unless otherwise indicated.
NOTE 2 In relation to the procedures set out in this part of the standard series, any special procedures specific
to a particular test method will be set out in that method standard.
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 and plant
biostimulants and where the following category organic fertilizers, organo-mineral fertilizers, inorganic
fertilizers, liming materials or inhibitors is the highest % in the fertilizing product blend by mass or
volume, or in the case of liquid form by dry mass. If the category (organic fertilizers, organo-mineral
fertilizers, inorganic fertilizers, liming materials or inhibitors) is not the highest % in the fertilizing
product blend, the European Standard for the highest % of the fertilizing product blend applies. In case a
fertilizing product blend is composed of components in equal quantity, the user decides which standard
to apply. Special care is needed to ensure that the fertilizing product blend is and stays homogeneous and
well mixed when sampled.
