Summary: The study estimated carbon stocks in tropical montane forests under different land uses and found that intact forests had the highest soil carbon stock, organic layer, and litterfall, while plantation forests had the lowest. Conserving intact forests is highlighted as an important strategy for carbon sequestration and climate change mitigation.

Summary: Tropical peat swamp forests in Peruvian Amazonia, particularly palm swamps, are at risk of degradation which can lead to the transformation of carbon sinks into carbon sources. This study estimated carbon emissions from degraded palm swamps and found that as degradation increases, the capacity of these swamps to sequester carbon decreases and they become high carbon sources. Therefore, sustainable management of these peatlands is crucial.

Summary: Reclamation of post mining soils by planting trees is of great research interest due to its potential to stabilize mine soils and sequester atmospheric carbon (C). However, there are knowledge gaps regarding the effect of different litter quality and biomass on the C sequestration vis-a-vis molecular characterization of soil organic carbon (SOC) in reclaimed mine soils. Results indicate that significant amounts of carbon accumulated under different tree species and the decomposition rate constant had a significant relationship with C/N ratio and nitrogen (N) content. Furthermore, spectroscopic methods could effectively distinguish differences in functional groups and molecularity of the humic acids derived from plant species of different resource quality and hence can be used in studying the quality of C sequestered.

Summary: The aim of this study was to understand the impact of the combination of no-till and cover cropping on soil organic carbon (SOC) and soil respiration. The results showed that for soils with high initial SOC contents, there was no significant difference in SOC and respiration between the conservation practices and conventional practices. However, for soils with low initial SOC contents, the conservation practices significantly increased SOC and respiration.

Summary: This study analyzed the soil respiration at four afforested sites in southern Taiwan with different tree species and examined the influence of seasonal variation and typhoon disturbances on carbon release. Results showed that different tree species led to variations in soil respiration, and severe typhoon impacts increased soil respiration levels.

Summary: Different forest types have seasonal effects on soil microbial activities, with mature deciduous forests showing the most sustainable microbial activities. The diversity of forest environments and the multifactorial dependence of microbiological activities in forest soils warrant further research to better understand forest ecosystem functioning. Continued analysis of the interrelationship between soil parameters and forest types with different tree ages is necessary for a more comprehensive understanding.

Summary: This study aimed to examine the responses of aboveground litterfall respiration to unexpected heavy snowfall events and soil temperature, moisture, rainfall, total litterfall, litter water content, nitrate nitrogen, and ammonium nitrogen. The results indicate that current global terrestrial models underestimate the trends of aboveground litterfall respiration for the feedback of global climate change in subtropical forests.

Summary: This study assessed the annual CO2 emissions from microbial carbon mineralization in a peatland site in Tierra del Fuego, finding that most CO2 emissions occurred in the warmer season. If agricultural activities are introduced to the study area, soil CO2 emissions from heterotrophic activity could become a significant source of global CO2 emissions.

Summary: This study developed and validated a predictive model for delta C-13 values in various soil profiles across Chile using near-infrared spectroscopy (NIRS). The partial least-squares regression (PLS) and random forest (RF) models showed acceptable performances, with RF model providing the best results. The results support the use of NIRS as a predictive method in soil analyses and as a nondestructive waste-free method for studies on carbon dynamics in soil.

Summary: Research on the impact of four biochars on soil properties, forage productivity, and greenhouse gas emissions reveals that different biochars can increase soil pH and total carbon content, promoting sorghum yield. Wood residue-derived biochar can reduce soil N2O emissions, while manure-derived biochar has potential in circular economy livestock systems.

Summary: This study investigates the relationship between carbon (C) mineralization, turnover, and the variation in delta C-13 signature with soil depth across a large geo-climatic gradient. Thirteen grassland sites in Chile were sampled, and near-infrared spectroscopy (NIRS) was used to estimate delta C-13 of soil organic carbon (SOC) at different depths. Soil incubations were performed to assess C mineralization rates and specific potential respiration, and the results showed significant positive relationships between Delta delta C-13 values and these proxies for C mineralization and turnover. The study highlights the importance of considering soil types and their properties in controlling Delta delta C-13.

Summary: Pyrolysis is a useful method for waste management, as it reduces greenhouse gas emissions and improves the stability of manure. This study found that using manure biochars as soil amendments can decrease CO2 and N2O emissions, improve carbon stability, and lower the global warming potential. The findings suggest that pyrolysis is a promising option for reducing the carbon footprint of farms and enhancing soil carbon stocks.
