Summary
ABSTRACT Microbial functional groups are heterogeneously distributed between soil aggregate fractions, which is strongly influenced by soil microenvironmental conditions. Intensive tillage practices disrupt soil aggregates, altering microbial niches and potentially affecting nitrogen (N) transformations, including processes leading to nitrous oxide (N 2 O) emissions. This study aimed to identify linkages between soil aggregation and microbial community functional composition using field samples after 20 years of differential tillage management: conventional mouldboard tillage (CT) and noninversion minimum tillage (MT). Soil properties, including soil organic carbon (SOC) and the abundance of total bacterial, archaeal and fungal communities and N‐functional guilds, were examined in two type
