International soil correlation implies international exchange of analytical data and this requires international comparability of data. A critical analysis of the reliability of laboratory data is important to give the user an idea about the error range all figures are associated with. A chemical or physical analysis determines a numerical yalue of a paranieter T his parametei has a 'true' value which is usually unknown and which the analyst tries to approximate as closely as possible applying certain procedures. In practice the results are scattered around this 'true' value. -

While the quantity and quality of soil data are fundamental, soil information must also be harmonized and globally consistent to have impact. The Global Soil Laboratory Network (GLOSOLAN) was established within the framework of the Global Soil Partnership’s fifth pillar in 2017. GLOSOLAN aims to facilitate networking and capacity development through cooperation and information sharing between soil laboratories with different levels of expertise. Proficiency testing is a key component of the GLOSOLAN implementation programme as it determines the performance of individual laboratories for specific analysis and is used to monitor laboratories' continuing performance.
