These are data accompanying a study that was carried out by a number of researchers from various organizations, including staff from the European Commission Joint Research Centre (Dr Alberto Orgiazzi).

The study resulted in a peer-reviewed scientific paper published in Global Change Biology: "Priming effects in soils across Europe" . The data are also availbable from the publication website.

The objectives of this study were (i) to quantify and compare the priming effect (PE) in 126 soils from cropland and seminatural (i.e., forests and grasslands) ecosystems, as well as in cropland soils cultivated with three important crop types in Europe: cereals, industrial crops and fruit and vineyard orchards; and (ii) model the main factors controlling the PE under contrasting land uses. PEs were measured after soil 13C-glucose addition and incubation at 20 °C for 35 days. These microcosms were also used to assess basal respiration for the same period. Soil and climate data were obtained from the same LUCAS 2018 survey and online databases. Data on microbial biomass C and enzyme activities were obtained from previous published studies. Bacterial and fungal biomass was quantified through fatty acid methyl esters (FAME) analysis. Random Forest analysis and structural equation modeling (SEM) were used to explore the main drivers of the PE.

On average, PEs were negative in seminatural and cropland soils, meaning that microbial communities preferentially switched from soil organic C (SOC) decomposition to glucose mineralization. PEs were significantly less negative in croplands compared with seminatural ecosystems and not influenced by the crop type. The input of easily available C sources (glucose) thus decreased SOC mineralization, and this decrease was stronger in seminatural ecosystems compared to croplands. Fresh organic C input contributes to the positive C balance not only by new SOC formation, but also by decreasing mineralization of existing SOC. Modelling showed that PEs were driven by soil basal respiration (reflecting microbial activity), microbial biomass C, and soil organic C, which were all higher in seminatural ecosystems compared with croplands.
