a Map of Europe showing sampling sites. b The nitrogen cycle with genes encoding the respective enzymes that catalyze the reactions and that were used in this study. In the nitrification process, amoA genes in both ammonia-oxidizing archaea (AOA) and bacteria (AOB) were quantified. For the abundance of prokaryotic and fungal communities, we quantified the 16S rRNA gene and the ITS2 region, respectively. Products and a selection of intermediates are shown by their chemical names. c Additional variables included were associated with management, climate, soil properties and microbial diversity, biomass, and activity. See Supplementary Table 1 for units.
