The document outlines the establishment and roles of fertilizer quality laboratories responsible for checking imported fertilizers and ensuring quality during transportation and local production. It emphasizes the need for harmonization of standard operating procedures and training for local blenders on sampling, packaging, and quality control. Additionally, it highlights the importance of informed labeling, environmental impact considerations, and the development of a monitoring system for fertilizer quality throughout the distribution chain.

Industry
Fertilizer quality laboratories –
officially appointed by their
government to check on the
quality of imported fertilizers
MAIN AREAS OF WORK
INFA Fertilizer Code
Ask the industry to use INFA
Standard Operating
Procedures.
If not possible, industry used
SOPs should be compared
with INFA SOPs
Harmonization of sampling
protocols (IFA already
published a SOP on this)
Notes:
1. Vinisa to check if quality guidelines for the industry already
exist at this level
2. Industry methods are based on AOAC, ISO, EN/EU
standards which are recognized validated methods
What can / should be done?
Please remember that INFA is meant to work
on laboratory analysisQuality of fertilizers
during transportation
ensured by the
manufacturers
However, secondary
stops should be
considered
Note: Problems start
when imported products
are modified, blended,
cut, etc. The initial
product is modified

4. MAIN AREAS OF WORK
INFA Fertilizer Code
Harmonization of sampling protocols
(IFA already published a SOP on this)
Develop a standard procedure on
fertilizer packaging. Packaging affects
fertilizer quality (link to moisture)
Train local blenders on sampling Train local blenders on fertilizer
packaging
Train local blenders on SOPs
implementation and QA/QC
Training farmers on fertilizer application
and quality control (there are some
easy techniques to use – contact IISS
Pradip Dey) and reading labels (link to
the Global Soil Doctors Programme).
Provide guidelines on fertilizer storage
(Vinisa to retrieve information on
already available guidelines)
Ensure that products released by local
blenders have an informative label.
Including the minimum guaranteed
content of the nutrients
Note: Problems start
when imported
products are
modified, blended,
cut, etc. The initial
product is modified
Farmers / Final users

modify imported products
and eventually do not check

5. MAIN AREAS OF WORK
INFA Fertilizer Code
1. Soil conditions and climate can change the assimilation conditions of the
fertilizer (FOR THE FUTURE)
Activity: improve labelling. Labels can mention that a specific fertilizer applied to a
specific soil type can result in differrent assimilation conditions
Fertilizer Code to work on labelling
INFA to work on soil-fertilizer interaction analysis. This is not an easy work, there is
the incubation time to keep into consideration. The response should be assessed
in the field. How can the industry provide these information?
The industry does agronomy field trials before commercializing fertilizers. It would
be important to have access to these information.
2. Environmental impacts of fertilizers to be stressed in labels
Farmers / Final users
Soil conditions

6. MAIN AREAS OF WORK
INFA Fertilizer Code
Quality standard
regulations. This refer to
the work of laboratories
Set up a fertilizer quality monitoring system:
- Visual assessment
- Packaging
- Transportation
- Labelling - minimum guaranteed content of the
nutrients
- Storage
- Training of stakeholders along the value chain
Create a database on national regulations on fertilizers
like SIMPLE. Work with SoiLEX

MAIN AREAS OF WORK

- Global
- Regional
Training (QA/QC, health and
safety, equipment use and

Procurement of equipment
Proficiency testing
Set up new laboratories as
needed
Define reference values or
classes for environmental
(pollution) risk and other (see
sustainability matrix of
GLOSOLAN)
Work on permissible limits
with national
governments. We cannot
generalize.

8. What type of fertilizers INFA should give priority to?
- Mineral fertilizers (PRIORITY 1)
- Organic fertilizers and amendments/improvers like manure, slurry,
substrate, sapropel and compost (PRIORITY 2). SOPs should consider the
microbial/microbiological component of this fertilizer type
- Liquid fertilizers
- Foliar fertilizers
- Bio-fertilizers
- Nano-fertilizer (suggestion from the chat). Commercial phrase and not a
class of fertilizers. They have health security concerns
Poll
Note: In the online survey, we asked for the type of fertilizer quality control performed at the
national level. Options are reported according to the answers provided. Mineral fertilizers are the
most analysed by respondents.
Before the 2nd INFA meeting we need to have a draft definition for each class of
fertilizer. Fertilizer definitions (Classes of fertilizers) are well defined in ISO 8157. We
can use this
Note: Most fertilizer analytical methods are common to both mineral and organic
fertilizers.
