Global Soil Laboratory Network 

Soils: if you cannot measure it, you cannot manage it

The Global Soil Laboratory Network (GLOSOLAN) was established in 2017 to build and strengthen the capacity of laboratories in soil analysis and to respond to the need for harmonizing soil analytical data. Harmonization of methods, units, data and information is critical to (1) provide reliable and comparable information between countries and projects; (2) allow the generation of new harmonized soil data sets; and (3) support evidence-based decision making for sustainable soil management.

The work of GLOSOLAN supports the implementation of the Sustainable Development Goals, the Agenda 2030 for Sustainable Development and the mandate of FAO on food security and nutrition. For more information contact [email protected]


What are GLOSOLAN main areas of work?

What are GLOSOLAN main areas of work?

GLOSOLAN is working to improve the proficiency of soil laboratories in both wet and dry chemistry (soil spectroscopy) by:


DRY CHEMISTRY (soil spectroscopy):

  • Build a globally representative calibrated soil spectral library (database) based on MIR spectra with accompanying soil property reference data recorded in one gold-standard reference laboratory;
  • Provide a freely available and easy-to-use soil property estimation service based on the evolving GLOSOLAN global MIR spectral library;
  • Support countries to contribute to the GLOSOLAN global spectral calibration library and use the soil property estimation service;
  • Harmonize soil spectroscopy methods (including soil sample preparation, spectral measurement and quality assurance of data analysis) by developing standard and protocols;
  • Develop the capacity of countries and labs in the performance of lab-based soil spectroscopy measurements.

GLOSOLAN was lately asked to look also after Fertilizers analysis. Through the establishment of the International Network on Fertilizers Analysis (INFA), GLOSOLAN is expected to:

  • Develop global and when appropriate regionally harmonized methods on fertilizers analysis;
  • Organize global proficiency tests on fertilizers;
  • Establish regional centers for training and doing the assessment of fertilizers quality;
  • Developing the capacity of laboratories in fertilizers analysis through training and equipment purchasing as appropriate.

How does GLOSOLAN work?

How does GLOSOLAN work?

GLOSOLAN is a participative network in which member laboratories and experts in soil analysis share their information and experiences at the purpose of developing harmonized standards and training material that are published on the GLOSOLAN webpage for free.

Please note that there is no registration fee or any annual cost to join GLOSOLAN.

Each member of GLOSOLAN matters! GLOSOLAN decisions are made using a bottom-up approach. Every year, laboratories from a same region are given the opportunity to discuss about their priorities and needs, and their position on topics to be discussed at the annual GLOSOLAN meetings. In this regard, countries are organized into Regional Soil Laboratory Networks (RESOLANs), the skeleton of GLOSOLAN. Therefore, it is the responsibility of the each RESOLAN Chair and vice-Chair to report about the position of his/her RESOLAN and make sure that regional requests are well included in the annual GLOSOLAN work plan.

In addition to the regional networks, GLOSOLAN is promoting the establishment of National Soil Laboratory Networks. Due to the lack of financial resources, the Global Soil Partnership of FAO is able to financially support the participation of only one person per country to the RESOLAN meetings. In this regard, it is important that laboratories organize themselves into national network. The establishment of National Soil Laboratory Networks is important for several reasons:

1. It promotes harmonization processes in soil analysis at the national level.

2. It facilitates the transfer of the knowledge acquired by laboratories participating in GLOSOLAN activities at the national level. Indeed, laboratories benefitting from GLOSOLAN training should transfer the acquired knowledge to other laboratories in their country. This process is critical also for overcoming language and cultural barriers.

Please consult the menu on the left to learn more on the Regional and National Soil Laboratory Networks.

What are the differences between National Reference and other registered soil laboratories?

What are the differences between National Reference and other registered soil laboratories?

In GLOSOLAN all registered laboratories have equal rights and opportunities!

Nevertheless, the Global Soil Partnership was forced to ask its national focal points to identify one champion laboratory (National Reference Soil Laboratory) that could lead the implementation of GLOSOLAN activities at the national level and transfer the knowledge acquired in GLOSOLAN to other laboratories. This request was due to the fact that GLOSOLAN works on a limited budget that cannot satisfy the requests for financial support of all registered laboratories.

Ultimately, priority is given to the National Reference Soil Laboratories in case of:

  • Shortage of soil samples for the execution of GLOSOLAN inter-laboratory comparisons;
  • Shortage of budget to cover participation costs to RESOLAN and/or GLOSOLAN meetings. Please note that financial support is provided as per FAO rules and procedures. In this regard, FAO can financially support participants from developing countries only.

Learn more about the Terms of Reference of National Reference Soil Laboratories and other laboratories registered in GLOSOLAN here (AR | EN | ES | FR | RU | TR). The performance of National Reference Soil Laboratories is monitored on an annual basis. GLOSOLAN will request national focal points for the replacement of any National Reference Soil Laboratory that does not comply with its role and tasks.

How can I register my laboratory in GLOSOLAN?

Fill out the form (EN, ES, FR) and send it to [email protected] and to [email protected]. Once your application is processed, your laboratory will be shown on the interactive map. At the moment of their registration in GLOSOLAN, all laboratories receive a letter and a certificate of registration. Please note these documents DO NOT certify the proficiency of laboratories in soil analysis. Therefore, they cannot be used to state that a laboratory is certified under GLOSOLAN or has a good proficiency in soil analysis. The performance of National Reference Soil Laboratories is monitored on an annual basis. GLOSOLAN will request national focal points for the replacement of any National Reference Soil Laboratory that does not comply with its role and tasks.
