Description (English):

This document is applicable to the sampling of mineral fertilizers and liming materials supplied or ready for supply to third parties, as a lot or in smaller lots, where such supply or readiness for supply is subject to legal requirements. This document specifies plans and methods of sampling of a lot of solid fertilizer or liming material, if sampling in motion is not possible, to obtain samples from bulk static heaps in order to ascertain compliance with legal requirements, in particular in relation to the accuracy of compulsory or permitted statutory declarations. The methods specified in this document are not applicable to obtain samples for physical size analysis or for chemical analysis which may be altered by particle granulometric segregation. This document is applicable to single nutrient fertilizers, to uniform complex fertilizers and to milled or granulated fertilizers and liming materials. The methods described in this document are not suitable for sampling other types of fertilizer, for example blended fertilizers. NOTE The term 'fertilizer' is used throughout the body of this document and includes liming materials unless otherwise indicated.

Abstract

Overview

ISO 14820-3:2020 - "Fertilizers and liming materials - Sampling and sample preparation - Part 3: Sampling of static heaps" provides standardized methods for obtaining representative samples from static heaps of mineral fertilizers and liming materials when sampling in motion is not possible. It is intended to support regulatory compliance and accurate statutory declarations by defining sampling plans, incremental sampling methods, and handling of aggregate/reduced/final samples for solid, single-nutrient, uniform complex, milled or granulated fertilizers (excluding blended fertilizers and tests affected by granulometric segregation).

Key topics and requirements

Scope and applicability: Sampling of bulk static heaps subject to legal requirements; not for blended fertilizers or particle-size analyses affected by segregation.
Lot characterization: Record physical properties before sampling - kind/type, texture, colour, storage conditions and presence of foreign matter.
Sampling plan elements: Must define lot boundary, volume/mass, number and location of sampling units, selected sampling units for increments, sketch-map (if needed), sampling points and minimum increment mass.
Sampling units: Total number of sampling units is based on lot size (e.g., minimum 10 units for lots ≤25 t; rules apply for larger lots up to >400 t).
Random selection: At least 10 sampling units must be selected randomly (random number tables/generator) for incremental sampling.
Incremental sample mass: Minimum increment from a sampling unit is 250 g; for liming materials coarser than 80 % passing 0.315 mm, each increment should be at least 500 g.
Volume/mass determination: Use production/purchase/sales records or estimate using methods in Annex A.
Sample processing: Incremental samples from units are combined to form aggregate, reduced and final samples in accordance with ISO 14820-1 procedures; final sample packaging and handling are specified to preserve representativity.

Practical applications

Ensures representative sampling for regulatory conformity checks, statutory nutrient declarations, and quality control where heaps are static.
Useful at farms, fertilizer production sites, warehouses, ports and distribution centers where bulk heaps are stored.
Supports laboratories and QA/QC teams to follow standardized procedures for sampling, chain-of-custody and final sample preparation prior to analysis.

Who should use this standard

National regulators and inspection authorities enforcing fertilizer/liming material legislation
Fertilizer manufacturers, packers and traders for compliance and dispute resolution
Accredited testing laboratories performing chemical or compositional analyses
Quality managers and auditors responsible for sampling protocols

Keywords: ISO 14820-3:2020, fertilizer sampling, static heaps, liming materials, sampling plan, incremental sampling, representative sample, regulatory compliance.
