The Soil Ringtest programme is running every third year. The normal schedule is:
When a lab did not qualify and did not make efforts to improve the data quality, ICP Forests PCC will send a letter to the National Focal Centre and inform them about the consequence that their data possibly cannot be used for evaluations on an European level.
The ringtest is financed with a participation fee and ringtest sample preparation from participants.
Please, keep in mind that submission of the monitoring results to the PCC database is only possible if your lab participated in the ring test for all submitted parameters. If you want to participate and you need a labcode or/and a password - please, contact Tamara Jakovljevic.
