10. By way of derogation from paragraph 9 of this Article, Member States may decide, before the second and subsequent sampling campaigns, not to carry out new soil measurements for a soil descriptor in part or in all of their territory if it is reasonable and justified to expect, based on data previously collected pursuant to this Article and Articles 6, 7 and 8, and on the use of scientific evidence, including predictive soil models, supported by a statistically significant amount of field data in terms of geographical and temporal coverage, that the value of such soil descriptor has not evolved significantly with respect to the uncertainty of the measurement since the last monitoring cycle. Member States shall notify the Commission of any such decision without undue delay.
The derogation laid down in the first subparagraph shall not apply as regards the carrying out of soil measurements for the same descriptor over two consecutive sampling campaigns.
