Summary: The study found that SOM content increases over time, with faster accumulation in forelands experiencing warmer climates. During the initial stages of soil development, low SOM content is dominated by a stable carbon pool. The stability of SOM decreases with soil age at all sites, suggesting that SOM storage is primarily influenced by the accumulation of labile SOM during the first centuries of soil development.

Summary: We investigated the composition of organic phosphorus (Porg) in different soil organic matter (SOM) fractions using sequential chemical fractionation (SCF) procedure combined with nuclear magnetic resonance (NMR) spectroscopy. The SCF procedure extracted a higher amount of Porg compared to a single-step extraction. Approximately 38% of the extracted Porg was in the form of unresolved Porg pool, represented by broad signals in the phosphomonoester region of NMR spectra. The SCF revealed the recovery of phosphomonoesters in different SOM fractions, with a portion closely associated with the soil mineral phase. The extractability of inositol phosphates (IP) was also increased using the SCF procedure.

Summary: Mineral-associated organic matter (MAOM) is the largest soil carbon pool, but the understanding of different organo-mineral fractions and their response to environmental variables is limited. In this study, sequential chemical extraction was used to separate MAOM fractions and alpine forest soils were selected to assess their response to climate change. Residual and weakly adsorbed organic matter were the primary fractions, and climate indirectly affected their preservation through weathering and environmental factors. The organo-mineral fractions were closely associated with metal cations and secondary minerals, forming complex networks. Water-soluble, weakly adsorbed, and Fe/Al oxyhydroxide-stabilized organic matter played central roles in the networks and were related to soil pH, moisture, and microbial composition. Additionally, climate and weathering factors greatly impacted Fe/Al-OM complexes, oxyhydroxide-stabilized organic matter, and residual organic matter. The complex network among organo-mineral fractions provides insights into MAOM preservation under climate change.

Summary: This study investigated polycyclic aromatic hydrocarbons (PAHs) in the soils of three proglacial areas in France and Italy. The results showed that the PAH content and the PAHs/TOC ratio in the soil changed exponentially and logarithmically with soil age. The study also found that the oldest soils had a similar PAHs/TOC ratio to soils from 1850 CE, indicating an equilibrium between these parameters in soils older than 170 years. Additionally, the capacity of soils to store these pollutants changed over time.

Summary: The study demonstrated that fertilization significantly increased soil organic carbon (SOC) content and its fractions, with organic manure amendment having a greater impact on SOC accumulation. Macroaggregates were identified as the main sites of carbon sequestration, and the increase in carbon content led to greater instability in the carbon. Additionally, microbial biomass showed clear differentiation characteristics in macroaggregates, with small macroaggregates containing more microbial biomass and large macroaggregates inhibiting microbial activity.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
