Table 2.
Networks metrics of cross domain co-occurrence networks computed for each time steps (T0, 6 months, 12 months, 18 months and 24 months) and for each treatment (R0L0 = control, R0L1 = only legumes, R1L1 = legumes and fine residues, R2L1 = legumes and all residues) in the sandy and the clay sites, respectively
