The abundance and phylogenetic diversity of functional genes involved in nitrification were assessed in Rothamsted field plots under contrasting management regimes—permanent bare fallow, grassland, and arable (wheat) cultivation maintained for more than 50 years. Metagenome and metatranscriptome analysis indicated nitrite oxidizing bacteria (NOB) were more abundant than ammonia oxidizing archaea (AOA) and bacteria (AOB) in all soils. The most abundant AOA and AOB in the metagenomes were, respectively,  Nitrososphaera  and  Ca.  Nitrososcosmicus (family Nitrososphaeraceae) and  Nitrosospira  and  Nitrosomonas  (family Nitrosomonadaceae). The most abundant NOB were Nitrospira including the comammox species  Nitrospira inopinata, Ca.  N. nitrificans and  Ca . N. nitrosa. Anammox bacteria were also detected .  Nitrospira and the AOA Nitrososphaeraceae showed most transcriptional activity in arable soil. Similar numbers of sequences were assigned to the  amoA  genes of AOA and AOB, highest in the arable soil metagenome and metatranscriptome; AOB  amoA  reads included those from comammox Nitrospira clades A and B, in addition to Nitrosomonadaceae. Nitrification potential assessed in soil from the experimental sites (microcosms amended or not with DCD at concentrations inhibitory to AOB but not AOA), was highest in arable samples and lower in all assays containing DCD, indicating AOB were responsible for oxidizing ammonium fertilizer added to these soils.

Metagenomic approaches reveal differences in genetic diversity and relative abundance of nitrifying bacteria and archaea in contrasting soils
