It is important to use methodologies for soil testing that are certified by internationally recognised bodies, such as the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN), as well as acknowledged by the global research community, provided that such methodologies are available. It is also possible to use for soil testing other equivalent methodologies, namely analytical procedures that determine the same parameter or descriptor and are proven to produce identical results within the margin of their repeatability coefficient (0,95). Certification of any equivalent methodologies should also be obtained from internationally recognised bodies, such as the ISO and the CEN, and such equivalent methodologies should be acknowledged by the global research community.
