Appendix A. Residual maximum likelihood (REML) results of the influence of plant traits (physiological and belowground and whole plant traits), as explanatory factors on key microbial parameters(DEA and NEA) in adherent soil.

Table A1. Residual maximum likelihood (REML) results of the influence of plant traits ((a) physiological, and (b) belowground and whole plant traits), as explanatory factors on key microbial parameters (DEA and NEA) in adherent soil. Fertilization was used as random factor. Presented are the p values, the amount of variation explained by each plant and microbial parameters and its direction of effect.
