Overview
EN 1482-2:2024 - "Fertilizers, liming materials and inhibitors - Sampling and sample preparation - Part 2: General sample preparation provisions" (CEN) defines methods for reducing and preparing samples of fertilizers, liming materials, inhibitors and their blends for subsequent chemical and physical analysis. The standard sets requirements for preparing test samples and test portions from laboratory samples, describes required apparatus and handling, and requires a sample preparation report. It supersedes EN 1482-2:2007 and includes updates such as added storage requirements.
Key topics
- Scope and exclusions
- Applies to solid and liquid fertilizers, liming materials and inhibitors, including specified blends.
- Does not cover preparation for physical tests that require test portions larger than 2 kg.
- Principles
- Reduction and division of laboratory samples to produce representative test samples and test portions.
- Emphasis on speed and cleanliness to minimize moisture changes and contamination.
- Apparatus and tools
- Rotary sample dividers or riffle dividers, sample grinders (with screens or equivalent), mortar and pestle, test sieves (ISO 3310‑1 sizes), and closable sample containers.
- Requirements to check grinder performance (fineness, temperature rise, contamination).
- Procedures
- Preparation of test samples in original condition (typical test sample ≈ 0.5 kg) using reduction/division methods (refer to EN 1482‑1 for sampling reduction procedures).
- Preparation of test portions for physical testing, moisture analysis and other chemical analyses; guidance when grinding should be avoided.
- Special handling for products difficult to grind, organic matter, multi‑component blends and liquids.
- Storage and labelling
- Storage requirements added (e.g., some laboratory samples for specific tests must be kept at 0 °C to 25 °C and not ground).
- Mandatory sample preparation report documenting methods, deviations and sieve sizes used.
Applications
- Quality control and laboratory analysis workflows in fertilizer production and distribution.
- Regulatory compliance testing for fertilizer composition and safety.
- Agricultural laboratories, commercial testing labs, manufacturers, QA/QC teams and certification bodies that require reproducible, representative test portions for chemical and physical analysis.
- Useful when sampling and preparing blended fertilizing products to ensure homogeneity and traceability.
Related standards
- EN 1482‑1:2024 - General sampling provisions (directly referenced for sampling/reduction procedures)
- EN 12944‑1 - Vocabulary / general terms used in fertilizers
- ISO 3310‑1 - Test sieves (referenced for sieve aperture sizes)
- Other ISO methods referenced in the standard’s bibliography for reduction and sampling principles
EN 1482-2:2024 is essential for practitioners who need consistent, reproducible sample preparation protocols for fertilizers, liming materials and inhibitors to achieve reliable chemical and physical test results.

1 Scope
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.
