L'AREFLH est partenaire du projet européen LivingSoiLL. Sa devise est "Healthy Soil to Permanent Crops Living Labs" (laboratoires vivants pour des cultures permanentes aux sols sains)
Ce mois-ci, nous partageons l'article « Science Beneath Our Feet » de Ruth Pereira de l'Université d'Aveiro. Elle est directrice de GreenUPorto – Centre de recherche pour la production agroalimentaire durable, et coordinatrice scientifique du laboratoire associé INOV4Agro. Ses recherches portent sur l'écotoxicologie terrestre et aquatique, l'évaluation des risques des sites contaminés et des substances chimiques émergentes, et la santé des sols, avec un accent particulier sur les indicateurs chimiques et biologiques.

Comment on Froger et al., 2024, paper:
"Under the upcoming Soil Monitoring Law (SML), EU Member States (MS) will be required to assess and monitor soil health across their territories. This data will support decision-making on sustainable soil management and restoration practices, such as increasing soil carbon storage.
Soil monitoring at the EU level is relatively recent, while some MS have had national soil information monitoring systems (N-SIMS) in place for decades. However, there is a lack of harmonization across MS, with varying sampling designs, soil properties measured, and data coverage. This makes comparisons difficult.
The LUCAS topsoil survey has emerged as a promising approach to harmonize data collection across Europe, but it also has limitations: underrepresentation of certain land uses, shifting sampling locations between campaigns, inconsistent depth sampling, and limited analysis of some soil parameters.
Froger et al. (2024) evaluated the feasibility of combining LUCAS data with N-SIMS, focusing on three soil properties (clay content, organic carbon [OC], and pH) and two soil health indicators (OC/clay ratio and pH classes). They found that only clay content showed consistency across both monitoring systems. Discrepancies in the indicators were attributed to differences in sampling depth, design, and analytical methods.
The authors conclude that N-SIMS and LUCAS serve different but complementary purposes, and neither can replace the other. Harmonizing analytical protocols is not advisable, as it would hinder MS from using historical data. Instead, efforts should focus on including common measurements in N-SIMS, using common sampling sites to develop transfer functions, and estimating uncertainty between methods.
Finally, the paper stresses that while harmonization is difficult at the national level, it is essential within Living Labs (LLs) and experimental sites to ensure comparability and transferability of practices. The adoption of the LUCAS methodology in LLs can enhance soil monitoring, support the EU Soil Mission, and demonstrate the contribution of LLs to improving soil health on a continental scale."
