Summary: The conversion of drylands to paddy fields on former wetlands in the Sanjiang Plain of northeast China enhances the soil organic carbon stock by promoting the accumulation of labile carbon fractions. Labile carbon fractions are more sensitive to this successive land-use change than recalcitrant carbon fractions.

Summary: This study aims to explore the relationship between bedrock exposure rates and soil labile organic carbon fractions (SLOCFs) in karst rocky desertification areas, and identify the limiting factors for SLOCFs. The results showed that concentrations and stocks of SLOCFs decreased with increasing soil depth, while light fraction organic carbon (LFOC) decreased with increasing bedrock exposure rate. The carbon pool management index and sensitivity index differed significantly under different bedrock exposure rates. The increase in bedrock exposure rate had a great impact on microbial biomass carbon (MBC), dissolved organic carbon (DOC), easily oxidized organic carbon (EOC), and soil organic carbon (SOC). The presence of secondary forest improved the integrity of karst landscapes without affecting the soil properties and concentrations and stocks of SLOCFs in karst rocky desertification areas.

Summary: Alterations of soil characteristics accompanying different land uses have a significant impact on the overall ecosystem, particularly on soil carbon stores and atmospheric CO2 emissions. This study conducted in a subtropical region examined the effects of six contiguous land uses on CO2 emissions and analyzed soil microbial respiration, microbial metabolic quotient, soil organic carbon, and microbial biomass carbon. Pasture and woodland displayed the highest soil microbial respiration, while tea land and uncultivated land showed increased microbial metabolic quotient. Pasture and forest areas had higher soil organic carbon and microbial biomass carbon compared to other land uses.

Summary: A study conducted in Ontario, Canada found that the cultivation of switchgrass and miscanthus, two perennial biomass crops, can significantly increase soil organic carbon (SOC) sequestration, contributing to Canada's goal of achieving net-zero greenhouse gas emissions by 2050. However, long-term field research in Canada is limited, highlighting the need for more empirical studies.

Summary: The restoration of degraded lands and minimizing land degradation are important tasks in global environmental land management schemes. Soil organic carbon (SOC) is a key indicator of soil productivity and influences soil ecosystem services. Detecting changes in SOC stock within a short timeframe presents a challenge for land managers. This study aimed to identify early indicators of changes in SOC stock and their drivers by synthesizing global data on the impacts of land use change on SOC fractions and soil structural properties. The conversion of arable lands to forests and grasslands resulted in a significant increase in SOC fractions and soil structural stability. The study also found that certain SOC fractions, particularly particulate organic C and organic carbon stored in small macroaggregates, were strongly correlated with total SOC and can serve as suitable indicators of short-term changes in SOC stock. Further field studies are needed to validate the findings of this study and assess the applicability of SOC metrics under different land use change scenarios.

Summary: Carbon sequestration in soils and plant biomass is seen as an important means to mitigate climate change. However, it is influenced by climate warming, nutrient limitations, and local land use. A study conducted in the UK revealed that realistic targets for grassland restoration and afforestation can enhance carbon sequestration potential by an additional 120 TgC, but this is conditional on climate change being controlled below 2 degrees Celsius. Conversely, arable expansion would decrease carbon storage. The study concludes that concerted land use change can contribute to national-level carbon sequestration, but it is dependent on global reductions in emissions from fossil fuels, deforestation, and soil degradation.

Summary: This study selected different land-use types in karst areas and analyzed the relative contributions of leaf and fine root inputs and fine root protection to soil carbon and nitrogen sequestration. The results showed that fine root protection was the dominant process for soil carbon and nitrogen changes, and active nitrogen input can increase soil nitrogen sequestration.

Summary: This study conducted a seven-year warming experiment in a coastal wetland in the Yellow River Delta and found that climate warming led to a decrease in soil organic carbon content, especially in the topsoil. Additionally, warming reduced the content of labile organic carbon, including dissolved organic carbon and particulate organic carbon, through increased soil salinity. However, it did not affect the content of recalcitrant mineral-associated organic carbon. The findings highlight the importance of considering the varying responses of different soil organic carbon fractions to warming for accurate projections of soil organic carbon dynamics in coastal wetlands under future climate change.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
