Table 2 Relationship between soil microbial community composition (or C-decomposition genes composition) and environmental attributes revealed by Mantel test

From: Nitrogen deposition experiment mimicked with NH4NO3 overestimates the effect on soil microbial community composition and functional potential in the Eurasian steppe
