Register as a soil sampler


Does a soil management expert ask you to collect soil or groundwater samples for a soil survey? Have you been asked by an Expert or an Authorised Installation (AI) for soil storage or processing to sample in situ or excavated soil in order to produce a Soil Quality Report (SQR)?

You must be registered with the SPW ARNE (Agriculture, Natural Resources and Environment) as a "Soil Sampler" in order that the analytical results of the soil, groundwater or soil samples, which you have collected, will have official value.



The soil sampler is one of the main players in the system for the sustainable management of Walloon soils implemented by the Soil Decree. However, this requires the use of professionals who are qualified in their field.

By registering you as a soil sampler in this context, the SPW ARNE recognises that you have the necessary means to accomplish your missions while meeting the legal requirements in force in your field.



In order to apply for a registration number, you must have completed the Basic Soil Sampler training module provided by the ISSEP (The Scientific Institute of Public Service).

This addresses the methods for:
      • collecting
      • sampling
      • packaging
      • and preservation of samples

These methods are described in the:
      • Walloon compendium of sampling and analytical methods (CWEA)
      • Walloon Code of Good Practice (CWBP) which includes the Reference Guide to Land Management (GRGT)

The basic module also provides an overview of the current legislation.

Have you not been able to attend this training so far? You will need to commit yourself to attend the training as soon as it can be arranged.



In order to apply for a registration number, please fill in the form provided and attach to it the seven required annexes. Please send your file by email to the administration according to the procedure described below.
