Abundances of a total bacteria (16S rRNA gene) and b fungal (ITS) in continuous cropping (CC), temporary grassland (TG) and perennial grassland (PG) soil samples (mean ± s.e.). The percentage of c ammonia-oxidizing archaea (AOA) to ammonia-oxidizing bacteria (AOB). Percentage of d AOB, e and f bacterial denitrifiers (nirK and nirS), g nitrogen-fixing communities (nifH) and h DNRA communities (nrfA) in the total bacterial community. Different letters above the bars indicate significant differences between land uses according to Dunn’s test (adjusted p-value < 0.05)
