Global Soil Partnership

Spectroscopy

Spectroscopy is the study of the interaction between matter and electromagnetic radiation. It is based on the principle that molecular vibrations and electronic transitions associated with soil constituents absorb light while interacting with radiation. For the first time since the discovery of this technology, institutions and experts from around the world are now joining efforts to use this technology to support decision making on soil protection globally.

With the support of its partners, GLOSOLAN aims:

  • To support the development of all types of soil spectroscopy at national, regional, and global levels. To achieve this objective, this initiative will be supervised by a group of experienced scientists to ensure that all activities are science based.
  • To support countries in establishing their own soil spectral laboratories and national soil spectral libraries with standardized methods and decentralized estimation services. To achieve this objective, GLOSOLAN will be using a country-driven approach and invest in capacity building activities at the national or regional level.
  • To continuously support the development of the global spectral estimation services by encouraging countries to share part of existing national soil spectral libraries on a voluntary basis. 
  • To support the development of standards and protocols for soil spectroscopy, including but not limited to soil sample preparation, measurement protocols, quality assurance, and data analysis and modelling.

Why to invest in soil spectroscopy?

Why to invest in soil spectroscopy?

Soil spectroscopy is a method that has the potential of more rapidly and cost-effectively measuring soil properties in the lab and in the field. Soil spectral analysis estimates soil properties by calibrating conventional reference measurements, like wet chemistry soil tests, to the spectral signatures. The potential of spectral technology in soil mapping and monitoring is tremendous as it is fast, cost-effective, environmentally friendly, nondestructive, reproducible and repeatable. Numerous soil properties can be directly calibrated to near- and mid-infrared spectra (MIR) due to the fact that spectral signatures respond to soil mineral and organic composition. 

Why is GLOSOLAN investing in soil spectroscopy?

Why is GLOSOLAN investing in soil spectroscopy?

By recognizing the potential of spectral technology in soil analysis and soil mapping and monitoring, GLOSOLAN aims to address the constraints that still hamper the wider uptake of this technology. Major constraints include (1) the lack of standards and protocols to ensure compatible spectral measurements across laboratories, (2) the lack of calibrated spectral libraries for different soil types and geographies, and (3) the lack of capacity of conventional soil laboratories in spectral methods.

Regional Champions on Soil Spectroscopy

How were the regional champions in soil spectroscopy selected?

How were the regional champions in soil spectroscopy selected?

In 2020, laboratories and institutes that expressed interest in the role of regional champions in soil spectroscopy were invited to complete a form to introduce themselves and indicate how they would be able to comply with the Terms of Reference. Candidate profiles were sent to the Regional Soil Laboratory Networks that elected their regional champions.

What is the duration of the mandate of the regional champions in soil spectroscopy?

What is the duration of the mandate of the regional champions in soil spectroscopy?

There is no time limit or term limit for the regional champion laboratories and/or institutes. Regional champion laboratories and/or institutes retain their role as long as they comply with the Terms of Reference outlined in this document. If necessary, a position will be revised at the first available plenary meeting on spectroscopy.

 

To learn more about the regional champions serving your region and the type of support they can offer laboratories in need and GLOSOLAN, please consult the interactive map below, by clicking on the icon displayed.

The map reports laboratories with different symbols and colors, according to their function:

  • Laboratories marked with stars are the Regional Champion Laboratories, they have different colors based on the region they serve;
  • Laboratories marked with flags act as Sub-Regional Champion Laboratories and they are also colored according to the region they are working in.
