Table S1. Quantitative PCR conditions used to estimate abundances of N-related microbial functional groups.

Table S2. Results of REML tests of individual plant and microbial parameters as explanatory factors for each ecosystem parameter.

Table S3. Alternative multivariable REML models for each of the ecosystem properties resulting from the replacement of plant and microbial traits retained in the original final models (Table 2) by alternatively significant collinear traits with an adjusted R² of >0.3.

Appendix S1. Detailed experimental protocol for the quantification of the abundance of nitrifiers, ammonia-oxidizing bacteria and archaea.
