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 Background and Aims: Highly weathered tropical forests are widely recognized as nitrogen (N)-rich phosphorus (P)-poor, the input of nutrienteffects soil carbon (C) cycling storage in these ecosystems. In topsoil, short-term nutrient additionmay not only effect organic C (SOC) pools directly, but also impact conversion process indirectly through altering microbial use efficiency (CUE). However, effects addition on accumulation mechanisms remain unclear. The aim this study was to clarify SOC responding addition. Methods: This conducted a one-year N P additions experiment forest Hainan, China. SOC, fractions (POC MAOC), biomass, enzyme activities, physicochemical properties at depths 0–10 cm, 10–20 cm 20–40 were measured. Results: results showed that increased (8.91–20.03%), POC (6.65–24.90%), MAOC (8.74–19.89%) topsoil (0–10 cm), whereas no significant changes occurred subsoil (20–40 cm). Pearson’s correlation analysis revealed litter biomass CUE significantly positively correlated with SOC. partial least squares-path model influences by characteristics. Conclusions:These suggested decreased activities. Such information could provide insight understand pool forest.

Abstract Background Unvegetated tidal flats of mangrove ecosystems in estuarine and non-estuarine areas play a crucial role the coastal blue carbon sinks biogeochemical cycle. However, there is still lack comprehensive understanding differences soil organic (SOC) contents between areas, as well their influencing factors. Methods In this study, samples were collected from Leizhou Peninsula. We compared SOC physicochemical properties flats. The Random Forest algorithm was employed to identify main factors affecting SOC. direct indirect effects on studied using partial least squares structural equation modeling. Results SOC, total nitrogen (TN), phosphorus (TP), available potassium (AK), clay, silt, aluminum (Al), lithium (Li), boron (B), molybdenum (Mo), cadmium (Cd) significantly higher than those particle size (clay, sand), nutrient (TN TP), metal elements (Al, Mo, Cd) flat areas.
