Abstract Soil dissolved organic matter (DOM) plays a critical role in regulating the cycling of terrestrial biogeochemistry. However, influence mechanisms nitrogen (N) addition on soil DOM concentration are not well understood at regional scale. We performed meta‐analysis 1004 paired observations from 115 literature to explore how N affected concentration, including carbon (DOC) and (DON), China. Overall, markedly stimulated DOC DON concentrations by 5.2% 33.1%, respectively. This implied that stimulation increased availability than suppression decreased pH played more important under addition. The level showed significantly positive correlation with was along increase initial total (TN). demonstrated microbial mining theory low soils stoichiometric decomposition high mean annual precipitation (MAP) potentially facilitated leaching out displayed negative impact depth depressed whereas indicated mostly accumulated top largely leached deep soil. And value perhaps promoted uptake for microbes solubility DON, thus resulted opposite influences concentrations. Our study provided mechanistic understanding C dynamics ecosystem

Abstract Dissolved organic matter (DOM) plays a key role in forest carbon biogeochemistry by linking soil (SOC) sequestration and water fluxes, which is further shaped elevated atmospheric nitrogen (N) deposition. Although enhanced SOC was evidenced tropical forests due to rising N deposition, it remains unclear how long-term inputs affect DOM composition, regulates capability its mobility biological instability. Here, the quantity, optical properties, molecular-level characteristics of based on simulative deposition experiment with four addition levels (0, 5, 10, 15 g m −2 yr −1 ) were studied primary south China. Results showed that 18 year additions significantly altered an increasing trend dissolved content. Medium- (10 high-N (15 markedly average molecular weight 12% aromaticity, specific ultraviolet absorbance at 254 nm 17%, modified aromatic index 35%, condensed aromatics 67%. also increased recalcitrant components but decreased other components, percentages lignin-like, tannin-like, carboxylic-rich alicyclic molecule-like compounds, decreasing percentage more bioavailable contributions H/C ratio >1.5. Importantly, significant correlations content heavy fraction properties observed. These findings suggest may alter composition way benefit OC storage forests. It merits focusing mechanisms association dynamics sequestration.

Recent frameworks have proposed that division of soil organic matter (SOM) into particulate and mineral-associated (POM MAOM) can help us better understand SOM cycling its responses to increasing atmospheric nitrogen (N) deposition. However, these factions N deposition with combination their relative distribution across profile remain unclear. Here we determined total carbon (SOC) as POM MAOM separately in soils at depths 0–10, 30–40 70–100 cm after 10-year addition (at rates 50, 10, 2 0 g m−2 yr−1) a typical steppe. We further calculated stocks POM, bulk detected relationships both physicochemical features microbial properties. Nitrogen increased the SOC (POM: +23 %; MAOM: +11 %) +27 +10 fractions topsoil (0–10 cm), but only (SOC: +24 N: +15 +13 soils. Moreover, effects were strengthened rates. found share was slightly decreased by topsoil, significantly deeper Soil exerted stronger controls than properties two regardless depth. contents correlated negatively pH profile, positively N, dissolved inorganic N. Our findings imply more C would be stabilized under deposition, therefore saturation level should target for studies considered predicting dynamics, especially N-limited grassland ecosystems.

The microbiome, an influential factor affecting plant health and growth, is attracting increasing interest with respect to wine grape production. purpose of this study was characterize the microbiome (fungi bacteria) soil, cover crop roots, (Vitis spp.) roots across rootstock depth in a cool-climate, organic vineyard. consisted fescue (Festuca sp.) grass, while were sampled from New York Muscat, cool-climate hybrid, three root types (ungrafted, 3309C Riparia Gloire) at depths (0 15, 15 30, 30 50 cm). more specialized, fewer observed amplicon sequence variants for both bacteria (16S) fungi (internal transcribe spacer) than found surrounding soil. Grape dominated by bacterial genera Pseudomonas, Niastella, Rhizobium; most prominent fungal Plectosphaerella, Trichosporon, Ilyonectria. Although no correlations between α-diversity metrics soil parameters, Pseudaleuria relative abundance correlated Mn, Fe, Na levels. Soil explained small portion but not variance taxonomic composition. Rootstock type composition, substantiating role host genetics development microbiome. This first characterization Canadian
