In the first 18 months, the project has made significant progress in developing the infrastructure to evaluate soil health across the EU. We have concentrated on five key activities. First, we have developed a robust indicator selection framework, and we are exploring new soil health indicators. Second, we established pilot sites and created field protocols and database standards, all contributing to the development of a sensor-fusion-based soil health assessment toolbox of the future, incorporating spectroscopy, genomics, and in-situ measurements. Third, we compiled and harmonized soil health data across various regions of Europe. Fourth, we worked on mapping soil health indicators at the pan-EU level. Lastly, we carried out activities to support the implementation of the Soil Monitoring Law.
Main achievements
The indicator selection framework has been formulated from previous policy and stakeholder needs, including consultation with the Joint Research Centre’s (JRC) Land Use and Coverage Area Frame Survey (LUCAS) soils team – and from synthesizing previous soil health indicators based on literature, policy and known databases across the EU, UK and elsewhere. A short synthesis of this work has been published and can be found here:

Multi actor engagement pilot sites have been set up across 11 different countries within different pedoclimatic conditions in the EU. These sites have identified various stakeholders and engagement strategies, as well as existing and new datasets to validate AI4SoilHealth predictions. We have also secured access to national datasets, data collection resources, and laboratory facilities for analysis. To ensure the production of harmonized data and storage, access and usability, we developed protocols for sampling methodology and an integrated data access system. We also selected the sensors (e.g. rapid enzymatic activity reader, and a soil temperature, moisture and salinity penetrometer) and methods (e.g. eDNA analysis, Beerkan water infiltration method, Moulder app for aggregate stability) to be tested within the pilot sites.
We have produced maps that represent or support the development of soil health indicators. All these maps are combined in a data cube, here called Soil Health Data Cube for Europe (SHDC4EU), and it is presented at 30-m spatial resolution and covering the period from 2000—2023+(

To support the Soil Mission and the Soil Monitoring Law, we are in contact with JRC, and we have published a short paper on the Soil Mission and an approach to soil health assessment. We have also written a paper on the UK soil monitoring experience with 5 decades of monitoring with design and development principles in support of the mission. We published a paper exemplifying the use of soil monitoring units for benchmarking soil health in Danish agricultural areas using SHIs and site-specific benchmarks, and we are working to implement it at Pan-EU scale with our new soil maps. We met with JRC colleagues in June to reprofile and refine the work priorities which are now being implemented. The major impact has been to reprofile work on vegetation cover, woodlands, and landscape heterogeneity to other soil descriptors, mostly carbon, salinity and biodiversity. The project is currently organising around internal clusters that will collaborate with a JRC representative with the cluster helping to set the agenda for the work plan.
