Abstract Soil pH is critically important in regulating soil nutrients and thus influencing the biodiversity ecosystem functions of terrestrial ecosystems. Despite ongoing threat nitrogen (N) pollution especially fast‐developing regions, it remains unclear how increasing N deposition affects across global By conducting a meta‐analysis with paired observations under addition control from 634 studies spanning major types ecosystems, we show that acidification increases rapidly amount most severe neutral‐pH soils. Grassland decreases strongly high while wetlands are least acidified. extrapolating these relationships to mapping, reveal atmospheric leads average decline −0.16 past 40 years regions encompassing Eastern United States, Southern Brazil, Europe, South East Asia hotspots deposition. Our results highlight anthropogenically amplified has profoundly altered chemistry. They suggest functions.

Abstract Emerging evidence points out that the responses of soil organic carbon (SOC) to nitrogen (N) addition differ along profile, highlighting importance synthesizing results from different layers. Here, using a global meta‐analysis, we found N significantly enhanced topsoil (0–30 cm) SOC by 3.7% (±1.4%) in forests and grasslands. In contrast, subsoil (30–100 initially increased with but decreased over time. The model selection analysis revealed experimental duration vegetation type are among most important predictors across wide range climatic, environmental, edaphic variables. contrasting indicate considering deep layers, particularly for long‐term continuous deposition. Finally, lack depth‐dependent modeling frameworks has likely resulted overestimation changes storage under

ABSTRACT Soil microorganisms are the most active participants in terrestrial ecosystems, and have key roles biogeochemical cycles ecosystem functions. Despite extensive research on soil pH as a predictor of microbial community composition, limitation these studies lies determining whether bacterial and/or fungal communities directly or indirectly influenced by pH. We conducted controlled laboratory experiment to investigate effects amendment (+/- 1–2 units) with six levels two contrasting Chinese agricultural soils (pH 8.43 Dezhou, located North China Plain, Shandong vs 6.17 Wuxi, Taihu Lake region, Jiangsu, east China). Results showed that diversity composition were related pH, but much lower than soils. The more closely associated Wuxi compared Dezhou alpha peaked near situ both soils, displaying quadratic fitting pattern. Redundancy analysis variation partition indicated affected imposing physiological constraint bacteria altering characteristics (e.g., nutrient availability). study also examined complete curves taxa relative abundances at phylum family response relationships conforming pattern, indicating is reliable predictor. Furthermore, transformation nitrogen functional genes involved cycle, methane production consumption. Overall, results from this would enhance our comprehension how farmlands will respond changes, contribute effective management conservation strategies.

Microorganisms are critical in forest ecosystems, where they secrete soil ecological enzymes and mediate nutrient cycling. These processes essential determining how these ecosystems respond to nitrogen (N) addition inputs. In this study, an N experiment was conducted with three levels of treatments a subtropical evergreen broad-leaved southwest China. The aim identify the effects low (LN: 10 g m− 2 year−1), medium (MN: 20 year− 1), high (HN: 25 1) on microbial community structure, diversity, enzyme activities, content, explore whether microorganisms influence activity Our observations indicated that surface exhibited highest contents. led reduction bacterial fungal diversity consistently higher than diversity. Moreover, structures were generally more diverse complex compared communities. study emphasized bacteria relatively enriched under LN treatment, while fungi relative abundance control conditions. Different groups distinct responses addition, inhibitory effect activities such as invertase (Inv), urease (Ure), acid phosphatase (ACP), enhancement catalase (CAT) activity. With increasing levels, organic carbon (SOC), total (TN), phosphorus (TP) contents decreased, whereas potassium (TK), nitrate (NO3−-N), ammonium (NH4+-N) opposite trend. Co-linearity network analysis revealed stronger interactions among fungi. dominant phyla Pseudomonadota Verrucomicrobiota showed correlations Ure ACP, respectively, Acidobacteriota correlation TP. Among phyla, Basidiomycota had CAT, NO3−-N, NH4+-N, Ascomycota notably associated Inv. results strong enzymes, nutrients. This implies have advantages secretion mediation, leading trend nutritional complementarity.
