“…). Our results are in line with findings of increasing OM decomposition and C processing under afforested sites, but contrast a subsequent decrease of decomposition and turnover of OM under continuous forest ( Richter et al, ; Diochon et al, ; Deng et al, ). Hampered approximated OM decomposition at continuously forested sites was observed if beta values were calculated excluding the litter layer, suggesting a strong impact of the organic layer as baseline for our approach.…”

Vertical gradients in stable carbon isotope ratios (δ13C) in soil profiles can serve to approximate decomposition of organic matter under field conditions. This study tested the time (0, 30, and ≥ 150 y) required for the development of vertical δ13C profiles in topsoil by comparing arable, afforested and continuously forested sites, and showed that three decades following afforestation of former cropland are sufficient to develop distinct δ13C depth profiles.

“…Our results show that vertical δ 13 C gradients can form within 30 y, similarly described in other studies ( Billings and Richter , ; Deng et al, ). According to our hypothesis, we found least developed δ 13 C depth profiles at arable sites and most developed δ 13 C depth profiles at continuously forested sites.…”

“…Given a set of soil quality indicators to assess the soil status in restored soils (Xu et al ; Muñoz‐Rojas et al ), the application of SR as an indicator of SOC sequestration and soil quality is meaningful and valuable for evaluating the effect of ecological restoration, because the condition of soils before restoration are never clear, and soil properties are inherently different in various eco‐regions, especially on the large spatial scales (Loescher et al ). Indicators of pooled SOC content and soil quality were strongly influenced by both historical condition and inherent difference of the soil (Deng et al ), hence, using these indicators to directly compare the effects of ecological restoration could lead to inaccurate conclusions (An et al ). SR normalizes the background differences of different eco‐regions or topographical conditions by including the properties of deeper soil.…”

The stratified distribution of soil organic carbon (SOC) provides a potential means of eliminating the difference in soil background for understanding its response to ecological processes. We assessed the feasibility of SOC stratification ratio (SR) as an index to estimate the dynamics of SOC sequestration and soil quality during ecological restoration. SOC, total nitrogen, and available nitrogen contents were measured at restored sites containing three vegetation types with different stand ages and slope gradients, also at sites with three kinds of agricultural management on the hilly Loess Plateau, China. SR and SOC density (SOCD) showed a consistently significant trend of linear increase along the revegetation chronosequences. The proportion of the annual increase rates of SR to SOCD were approximately 1:15 and 1:5 for SR1 (0–5:5–10 cm) and SR2 (0–5:20–30 cm), indicating that SR of the shallow soil layers (0–10 cm) could estimate SOC accumulation to a depth of 30 cm. SRs significantly increased owing to the ecosystem restorations. Also, SRs could discriminate the difference in SOC sequestration and soil quality between vegetation types. SR, however, could not precisely indicate the variation of SOC sequestration and soil quality under different agricultural management. The study suggested that SR was an efficient indicator of the dynamics of SOC sequestration and soil quality, and an SR2 (0–5:20–30 cm) >2 indicated a distinct improvement of SOC sequestration and soil quality in ecological restoration on the hilly Loess Plateau.

“…Globally, soil contains 1,500-2,300 Pg of organic C, approximately twice as much as the amount in the atmosphere and three times the amount in terrestrial vegetation (Lal, 2004). Therefore, it has an important role in regulating the atmospheric carbon dioxide (CO 2 ) concentration (Briones, Ostle, & Garnett, 2006;Deng, Wang, Tang, & Shangguan, 2016). Minor variations in soil C pools can significantly change the global C cycle (Davidson & Janssens, 2006).…”

The effects of nitrogen (N) deposition on soil organic carbon (C) and greenhouse gas (GHG) emissions in terrestrial ecosystems are the main drivers affecting GHG budgets under global climate change. Although many studies have been conducted on this topic, we still have little understanding of how N deposition affects soil C pools and GHG budgets at the global scale. We synthesized a comprehensive dataset of 275 sites from multiple terrestrial ecosystems around the world and quantified the responses of the global soil C pool and GHG fluxes induced by N enrichment. The results showed that the soil organic C concentration and the soil CO2, CH4 and N2O emissions increased by an average of 3.7%, 0.3%, 24.3% and 91.3% under N enrichment, respectively, and that the soil CH4 uptake decreased by 6.0%. Furthermore, the percentage increase in N2O emissions (91.3%) was two times lower than that (215%) reported by Liu and Greaver (Ecology Letters, 2009, 12:1103–1117). There was also greater stimulation of soil C pools (15.70 kg C ha−1 year−1 per kg N ha−1 year−1) than previously reported under N deposition globally. The global N deposition results showed that croplands were the largest GHG sources (calculated as CO2 equivalents), followed by wetlands. However, forests and grasslands were two important GHG sinks. Globally, N deposition increased the terrestrial soil C sink by 6.34 Pg CO2/year. It also increased net soil GHG emissions by 10.20 Pg CO2‐Geq (CO2 equivalents)/year. Therefore, N deposition not only increased the size of the soil C pool but also increased global GHG emissions, as calculated by the global warming potential approach.
