Download as PPTX, PDF1 like520 views
The Global Soil Laboratory Network (GLOSOLAN) aims to enhance the reliability and comparability of soil analytical results through the establishment of regional soil laboratory networks (RESOLANs). It emphasizes quality control and standardized methods to address discrepancies observed in soil data analysis across laboratories. Key activities include developing best practice manuals, engaging in international proficiency tests, and conducting regional capacity building for soil testing.
ITEM 14. GSP – The Global Soil Laboratory Network (GLOSOLAN) - Lucrezia Caon
- 1. Global Soil Laboratory Network (GLOSOLAN) Ms. Lucrezia Caon
- 2. Outcomes of the 5thGSP Plenary Assembly Endorsement of Pillar 5 Implementation Plan and support to its execution, includingthe establishment of regionalanda Global SoilLaboratory Network
- 4. Why should countries join GLOSOLAN and RESOLANs? Remember that most soil characterizations & recommendations are based on… Soil analytical results!
- 5. When sending a same soil sample to any soil lab…
- 6. When sending a same soil sample to any soil lab… …your expectation is to get the same result (+/- uncertainty)
- 7. When sending a same soil sample to any soil lab… …and to obtain the same soil classification or provide similar recommendations, etc.
- 8. In reality… Large differences are observed between laboratories (even for something as simple as pH)
- 9. P Laboratory(confidential code) pH Laboratory(confidential code) Example provided by SEALNET2.0 (ring test, South-EastAsia)
- 10. Inconclusion,if yousendthesamesoil sample to differentlabs… Sometimesyougetdifferentresultsandconclusions
- 11. Inconclusion,if yousendthesamesoil sample to differentlabs… But which laboratory is right?
- 12. To help answering this question, GLOSOLAN was launched on 1-2 November 2017 Main goals of GLOSOLAN: • To strengthen the performance of laboratories towards the development of standards • To harmonize soil analyses in order to make soil information across laboratories, countries and regions comparable and interpretable Overall, GLOSOLAN will help achieve the objectives of the 5 Pillars of Action of the GSP
- 13. Identify research gapse.g. which promising methods require refinement and furtherdevelopment? Area for investment, technical cooperation, extension services Provision of reliabledata to support the establishment of the Global Soil Information System(GLOSIS) Improve the basisfor decision making regarding e.g.soil fertility, SOCmanagement
