“…This is the largest fixed/semi-fixed temperate desert in China. The mean annual temperature and precipitation are 7.1 • C and 215.6 mm, respectively (Cui et al, 2017), and annual potential evaporation exceeds 2000 mm. From late November to mid-March, 20-35 cm of snow covers the whole desert (equivalent to 38-64 mm rainfall; Huang et al, 2015c).…”

“…In September 2014 to August 2016, an in situ complete block interactive experiment was therefore conducted to study the impact of N deposition and increased precipitation on R s . The three levels of N deposition (0 kg N ha −1 yr −1 , control, N0; 30 kg N ha −1 yr −1 , low, N1; 60 kg N ha −1 yr −1 , high, N2) and two levels of precipitation ("natural" precipitation, W0, and an increase of 30 % -an extra 60 mm precipitation annually, W1) were applied (Cui et al, 2017). Therefore there were six treatments (W0N0, W0N1, W0N2, W1N0, W1N1 and W1N2) with four replicates of each treatment.…”

Abstract. Soil respiration (Rs) is the most important source of carbon dioxide emissions from soil to atmosphere. However, it is unclear what the interactive response of Rs would be to environmental changes such as elevated precipitation, nitrogen (N) deposition and warming, especially in unique temperate desert ecosystems. To investigate this an in situ field experiment was conducted in the Gurbantunggut Desert, northwest China, from September 2014 to October 2016. The results showed that precipitation and N deposition significantly increased Rs, but warming decreased Rs, except in extreme precipitation events, which was mainly through its impact on the variation of soil moisture at 5 cm depth. In addition, the interactive response of Rs to combinations of the factors was much less than that of any single-factor, and the main response was a positive effect, except for the response from the interaction of increased precipitation and high N deposition (60 kg N ha−1 yr−1). Although Rs was found to show a unimodal change pattern with the variation of soil moisture, soil temperature and soil NH4+-N content, and it was significantly positively correlated to soil dissolved organic carbon (DOC) and pH, a structural equation model found that soil temperature was the most important controlling factor. Those results indicated that Rs was mainly interactively controlled by the soil multi-environmental factors and soil nutrients, and was very sensitive to elevated precipitation, N deposition and warming. However, the interactions of multiple factors largely reduced between-year variation of Rs more than any single-factor, suggesting that the carbon cycle in temperate deserts could be profoundly influenced by positive carbon–climate feedback.

“…The frost-free period lasts between 120 and 130 d and mean annual precipitation ranges from 695 to 983 mm yr −1 , most of which occurs between June and August (Lou et al, 2013;Wang et al, 2018a). The local soil is classified as darkbrown mountain forest albic soil according to the Chinese soil classification system, Alfisol according to the US soil taxonomy (Chen et al, 2017a;Shao et al, 2018), or Eutric cambisol according to the Food and Agriculture Organization of the United Nations classification (Wang et al, 2017). The parent materials of these soils originate from weathered volcanic ash and basalt.…”

Over 200 yr of ecosystem succession in northeastern China, conifers have replaced broadleaf trees. Vegetation changes during forest succession may affect soil organic C (SOC) stability, which is associated with altered protection mechanisms. Lignin phenol composition, a predictor of soil organic matter variation, was assessed for macroaggregates, microaggregates, and silt–clay (SC) fractions from successional gradients in five forests aged 19 to 239 yr in the Changbai Mountains nature reserve. The large macroaggregates (4.00–8.00 and 2.00–4.00 mm) comprised 45.17 to 59.87% of bulk dry weight and 40.22 to 60.89% of SOC in the 19‐, 32‐, and 48‐yr‐old pioneer forests. However, we detected increased mass proportions and SOC contents in small macroaggregates (1.00–2.00 and 0.25–1.00 mm) in the mixed broadleaf–Korean pine (Pinus koraiensis Siebold & Zucc.) forest after 122 yr. Lignin in bulk soil and aggregates in the 122‐yr‐old stand had lower acid/aldehyde ratios for the vanillyl and syringyl types than other stands, indicating less lignin decomposition. The highest C (198.20 g kg−1 soil) and lignin concentrations (6.14 mg 100 mg−1 C) were detected in the bulk soil from the 239‐yr‐old stand, where SC fraction occupied 56.18% of the C and 84.17% of the lignin content in bulk soil. Forest succession from broadleaf to a broadleaf–pine mixture shifted SOC sequestration and lignin protection from aggregates to SC fractions, along with the development of plant litter composition, fine‐root biomass and turnover, and microorganism biomass, which prompted effective long‐term SOC accumulation in successional forest communities.

An incubation experiment is conducted at 20 °C for 30 days to explore the influence of biochar, nitrogen, and their interactions on CH4, CO2, and N2O emissions, as well as C and N variations in soils with milk vetch and rape residue amendment or in soils without plant residue. Both the biochar and nitrogen additions had negative effects on the cumulative CH4 and CO2 emissions in the presence of milk vetch and rape residues. Regardless of the biochar and nitrogen addition, the CH4 and CO2 emissions from soils amended with milk vetch residue are the highest, followed by those from soils amended with rape residue and those from soils with no plant residue. With the N application, N2O emissions from soils amended with rape residue are significantly higher than those from soils without plant residue, whereas the N2O emissions from soils amended with milk vetch residue are significantly lower than those from soil without plant residue. DOC is positively related with CO2 emissions. NH4+N, NO3−N, and TIN are also positively correlated with N2O emissions. In soils with the N fertilizer application, milk vetch residue, and biochar decreases the global warming potential, whereas rape residue increases the global warming potential. The results indicate that milk vetch residue in combination with biochar could benefit greenhouse gas mitigation and should be recommended for agricultural practices at high nitrogen level. In contrast, rape residue incorporated with biochar should be applied cautiously, especially in N abundant soils.
