Introduction to the Global Soil
Laboratory Network (GLOSOLAN) and
compilation of regional inputs
Outcomes of the 5th GSP Plenary Assembly
(June 2017)
Endorsement of Pillar 5
Implementation Plan and
support to its execution,
including the
establishment of
regional and a Global
Soil Laboratory
Network
Regional Soil Laboratory Networks
(RESOLANs)
Why should countries join GLOSOLAN and
RESOLANs?
Remember that
most soil
characterizations &
recommendations
are based on…
Soil analytical
results!
When sending a same soil sample
to any soil lab…
When sending a same soil sample to any soil
lab…
…your expectation is to get
the same result
(+/- uncertainty)
When sending a same soil sample to any soil
lab…
…and to obtain the same soil
classification or provide
similar recommendations, etc.
In reality…
Large differences are observed
between laboratories (even for
something as simple as pH)

In conclusion, if you send the same soil
sample to different labs…
Sometimes you get different results and
conclusions
In conclusion, if you send the same soil
sample to different labs…
But which laboratory is right
?
To help answering this question
was launched on 1-2 November 2017
The purpose of GLOSOLAN is …
…to improve the quality of soil laboratory data
to support decision making at field and policy
levels, in support of the overarching goals of
eradicating hunger by achieving food security
and improving nutrition, and ensuring
environmental quality. In this context, the work
of GLOSOLAN is connected to the GSP Pillars of
Action.
Identify research gaps e.g. which promising
methods require refinement and further
development?
Area for investment,
technical cooperation,
extension services
Provision of reliable
data to support the
establishment of the
Global Soil Information
System (GLOSIS)
Improve the basis for decision making regarding e.g.
soil fertility, SOC management
GLOSOLAN’s objectives…
• To strengthen the performance of
laboratories through use of standardized
methods and protocols.
• To harmonize soil analysis methods so that
soil information would be comparable and
interpretable across laboratories, countries
and regions.
• To provide a certification for technical
competencies in laboratory analysis.
GLOSOLAN’s impacts….
– To support decision making at field and policy levels;
– To support countries in reporting on the Sustainable Development Goals and on
other international commitments;
– To contribute to the development of international standards and indicators;
– To contribute to the establishment of the Global Soil Information System (GLOSIS);
– To contribute to the development of harmonized methods for the assessment and
monitoring of degraded lands and/or lands affected by climate change and other
threats, as identified in the Status of the World Soil Resources report;
– To improve the connection between soil chemistry, physics and biology;
– To contribute to and improve soil classification and description;
– To assist companies manufacturing laboratory equipment in improving their
products;
– To expand the opportunities for technical and scientific cooperation;
– To strengthen the capability of extension services;
– To identify research needs; and
– To increase investments in research

Harmonization strategy
1. Harmonization of data obtained using different GLOSOLAN SOPs
PROPOSAL ENDORSED (Rich, USDA, USA)
Implementation Strategy:
- Soil parameter to harmonize at first: soil organic carbon.
- Data to harmonize: SOC data obtained using the Walkley-Black and the dry
combustion methods (reference to the GLOSOLAN work plan)
- Transfer functions will be developed on historical databases at first and thereafter
improved as needed.
- Data need: SOC data from soil samples analyzed using both the Walkley-Black and
the dry combustion methods
Harmonization strategy
1. Harmonization of data obtained using different GLOSOLAN SOPs
PROPOSAL ENDORSED (Rich, USDA, USA)
Implementation Strategy:
- USDA will make available their historical databases. Other partners complying with
the above mentioned requirements will be invited to share their databases and the
SOPs for the methods used. Data can be anonymized before submission. The
provision of geo-located data is optional. The USDA volunteered to run the
statistical analysis and develop the transfer functions. In order to facilitate data
entry, a form for data submission will be sent to partners sharing their databases.
Form to be prepared by the USDA and sent by the GSP Secretariat
- In order to assist in the process, the GSP will do a literature review on the
comparison of methods on SOC determination. Results will be presented at the 3rd
GLOSOLAN meeting
Harmonization strategy
2. Harmonization of data obtained using GLOSOLAN SOPs and ISO standards
PROPOSAL ABOLISHED
Not needed
3. Harmonization of data obtained using national methods and GLOSOLAN SOPs
PROPOSAL ENDORSED (Louise, BGS UK to support)
Survey those laboratories that cannot use GLOSOLAN SOPs. Eventually organize
trainings on the development of transfer functions.
4. Harmonization of historical databases – DISCUSSION POST-PONED
Waiting for results from point 1. It is going to be very difficult.

3. Evaluation of the first GLOSOLAN Proficiency Test
On Friday, I will give you all a bag with some soil samples to analyse.
Instructions on how to handle and analyse the samples, and on how to
report the results of the analysis will be provided.
