The objective of AI4SoilHealth is to co-design, create and maintain an open access European-wide digital infrastructure, compiled using state-of-the-art Artificial Intelligence (AI) methods combined with new and deep soil health understanding and measures. The AI-based data infrastructure functions as a Digital Twin to the real-World biophysical system, forming a Soil Digital Twin. This can be used for assessing and continuously monitoring Soil Health metrics by land use and/or management parcel, supporting the Commission’s objective of transitioning towards healthy soils by 2030.Read More
The Mediterranean economy is highly dependent on agriculture.
However, agricultural sustainability and productivity in this region are under serious threat due to climate change and depletion of water resources. This is worsened by poor management practices, such as the overuse of chemical fertilizers and pesticides, overgrazing, and monoculture farming. ReCROP aims to redesign Mediterranean agrosystems with improved resilience capacity and higher productivity, focusing on the development of sustainable agricultural production systems through the combined use of biotechnological tools and environmentally friendly agronomic practices. This will allow farming systems to face climate change trough the improvement of below and aboveground biodiversity, fertility, and water conservation. RECROP uses the novel approach of plant-microorganism management that relies on the increase of soils functions and health by using bioinocula, amendments, cropping systems, and climate-ready crops, to increase crop yields while providing ecological services, e.g., increasing carbon sequestration, organic matter, nutrient cycling and water conservation.

Here, we aimed to bioremediate organically contaminated soil with Brassica napus and a bacterial consortium. The bioaugmentation consortium consisted of four endophyte strains that showed plant growth-promoting traits (three Pseudomonas and one Microbacterium) plus three strains with the capacity to degrade organic compounds (Burkholderia xenovorans LB400, Paenibacillus sp. and Lysinibacillus sp.). The organically contaminated soil was supplemented with rhamnolipid biosurfactant and sodium dodecyl benzenesulfonate to increase the degradability of the sorbed contaminants. Soils were treated with organic amendments (composted horse manure vs. dried cow slurry) to promote plant growth and stimulate soil microbial activity. Apart from quantification of the expected decrease in contaminant concentrations (total petroleum hydrocarbons, polycyclic aromatic hydrocarbons), the eectiveness of our approach was assessed in terms of the recovery of soil health, as reflected by the values of dierent microbial indicators of soil health. Although the
applied treatments did not achieve a significant decrease in contaminant concentrations, a significant improvement of soil health was observed in our amended soils (especially in soils amended with dried cow slurry), pointing out a not-so-uncommon situation in which remediation eorts fail from the point of view of the reduction in contaminant concentrations while succeeding to recover soil health.
