Highly weathered lowland (sub)tropical forests are widely recognized as nitrogen (N)-rich and phosphorus (P)-poor, the input of N P affects soil carbon (C) cycling storage in these ecosystems. Microbial residual C (MRC) plays a crucial role regulating organic (SOC) stability forest soils. However, effects long-term addition on MRC across different layers remain unclear. This study conducted 12-year experiment two typical subtropical plantation dominated by Acacia auriculiformis Eucalyptus urophylla trees, respectively. We measured plant (fine root biomass, fine C, litter C), microbial community structure, enzyme activity (C/N/P-cycling enzymes), mineral properties, MRC. Our results showed that continuous reduced subsoil (20-40 cm) both plantations (A. auriculiformis: 28.44% E. urophylla: 28.29%), whereas no significant changes occurred topsoil (0-20 cm). decreased (25.44%), but had A. auriculiformis. Combined (34.63%) not urophylla. The factors varied layers. In (0-10 cm), (the relative contributions to total variance was 20%, hereafter) protection (47.2%) were dominant factors. layer 10-20 cm, characteristics (41.3%) (32.3%) substantial effects, deeper predominantly regulated (37.9%) (18.8%). Understanding differential drivers depth, particularly layers, is for accurately predicting SOC its responses chronic enrichment and/or increased limitation forests.

Abstract Microbial necromass carbon (MNC) accounts for a large fraction of soil organic (SOC) in terrestrial ecosystems. Yet our understanding the fate this pool under long‐term warming is uncertain. Here, we show that 14 years (+4°C) temperate forest resulted reduction MNC by 11% (0–10 cm) and 33% (10–20 cm). Warming caused decrease content due to decline microbial biomass reduced use efficiency. This was primarily warming‐induced limitations available phosphorus, which, turn, constrained production biomass. Conversely, increased activity extracellular enzymes, specifically N ‐acetylglucosaminidase leucine aminopeptidase, which accelerated decomposition MNC. These findings collectively demonstrate decoupling formation underlie observed loss climate warming, could affect SOC ecosystems more widespread.
