Acid rain and nitrogen deposition are emerging as global scale environmental issues due to increasing industrial emissions agricultural pollutants, which seriously impac t the sustainable development of ecosystems. However, specific effects both acid interactions on forest soil ecosystems, particularly relates nutrient content enzyme activities, remain unclear. Therefore, we established a simulated sample plot (SR, NR) (N) their (SRN, NRN) in subtropical Cunninghamia lanceolata ( C. ) plantation Yangtze River Delta region China investigate impacts these factors via correlation analysis structural equation model (SEM). The results showed that had stronger effect pH than plantation, while simultaneous addition exacerbated acidification. Soil available potassium, ammonium nitrate responded more obviously deposition, rain, significantly reduced potassium content, increased content.

Manganese (Mn) is a biologically important and redox-active metal that may exert poorly recognized control on carbon (C) cycling in terrestrial ecosystems. influences ecosystem C dynamics by mediating biochemical pathways include photosynthesis, serving as reactive intermediate the breakdown of organic molecules, binding and/or oxidizing molecules through organo-mineral associations. However, potential for Mn to influence storage remains unresolved. Although substantial research has demonstrated ability Fe- Al-oxides stabilize matter, there scarcity similar information regarding Mn-oxides. Furthermore, Mn-mediated reactions regulate litter decomposition pathways, but these processes are constrained across diverse Here, we discuss ecological roles environments synthesize existing knowledge multiple which biogeochemical intersect. We demonstrate high degrade abiotic microbially mediated oxidation at least temporarily, outline priorities needed advance understanding Mn-C interactions, highlighting gaps address key uncertainties soil predictions.

Understanding how N addition status (i.e., duration, rate, and form of addition) impacts carbon (C) cycling has great implications for C storage prediction grassland management. We examined 257 studies related to in grasslands obtained a dataset 1073 observations meta-analysis. significantly increased plant input (plant above-ground biomass +49.1%, below-ground +16.6%; litterfall +17.4%; dissolved organic +16.4%) across natural globally. For loss processes, enhanced litter decomposition by 9.2% decreased soil respiration 1.1%. In topsoil, microbial was reduced 8.7% (SOC) content 3.1%. fluxes, gross primary productivity ecosystem 24.7% 11.7% respectively, leading negative net exchange. These results indicated that were sinks under addition. Besides climate, the duration most important factor affecting cycling. The response SOC with time but weakened after decade, associated accumulative effects N-induced acidification. at any rate or temperate grassland/meadow while other depended on status.

Enhancing soil carbon (C) storage has the potential to offset human-caused increases in atmospheric CO2 . Rising occurred concurrently with increasing supply rates of biologically limiting nutrients such as nitrogen (N) and phosphorus (P). However, it is unclear how increased supplies N P will alter C sequestration, particularly grasslands, which make up nearly a third non-agricultural land worldwide. Here, we leverage globally distributed nutrient addition experiment (the Nutrient Network) examine decade fertilization (alone combination) influenced stocks at nine grassland sites spanning continental United States. We measured changes bulk three fractions (light heavy particulate organic matter, mineral-associated matter fractions). amendment had variable effects on pools that ranged from strongly positive negative, while pool sizes varied by more than an order magnitude across sites. Piecewise SEM clarified small plant inputs did not translate greater storage. Nevertheless, peak season aboveground biomass (but root or production) was positively related seven sites, all covaried moisture index mineralogy, regardless fertilization. Overall, show site factors index, productivity, texture, mineralogy were key predictors cross-site C, weaker site-specific sequestration. This suggests prioritizing protection highly productive temperate grasslands critical for reducing future greenhouse gas losses arising use change.

Climatic change severely affects terrestrial ecosystem functioning by modifying soil microbial communities, especially in arid ecosystems. However, how precipitation patterns affect microbes and the underlying mechanisms remain largely unclear, particularly under long-term dry-wet cycling vice versa field settings. In this study, a experiment was conducted to quantify responses resilience changes with nitrogen addition. We established five levels of addition over first 3 years then balanced compensatory fourth year (i.e., reversed treatments), recover expected 4 desert steppe ecosystem. Soil community biomass increased increasing precipitation, these responses. The response ratio constrained initial reduction whereas limitation/promotion index most groups tended increase. Nitrogen reduced rates groups, depending on depth. could be distinguished antecedent features. regime can regulate communities climatic via two potential mechanisms: (1) concurrent deposition (2) chemical biological mediation. behaviors their associations properties should considered when assessing ecosystems change.
