Research Progress | The Research Team of Editor Feng Xiaojun Reveals the Response of Metal-Bound Organic Carbon to Drainage: Sphagnum vs. Non-Sphagnum Wetlands

Wetlands are the terrestrial ecosystems with the highest carbon density and are severely threatened by drainage, with significant uncertainty regarding the response of their soil carbon pools to drainage. Traditional views suggest that soil organic carbon (SOC) in wetlands is primarily composed of undecomposed or partially decomposed particulate organic carbon (POC), which is prone to … Read more

Does Periodic Hypoxia Accelerate SOC Decomposition in Soil?

Abstract: The decomposition of soil organic carbon (SOC) is fundamental to soil-atmosphere carbon exchange and is regulated by changes in soil redox conditions mediated by climate change. Periodic hypoxia typically occurs after precipitation, soil flooding, and erosion events, and it is believed to preserve SOC. However, water saturation may also increase SOC decomposition compared to … Read more

Existing and Emerging Methods for Assessing Soil Organic Matter (SOM) Dynamics

The assessment methods for Soil Organic Matter (SOM) dynamics are crucial for understanding the soil carbon cycle and predicting changes in soil carbon storage. Existing methods are centered around traditional paradigms, while emerging methods have made progress in theory, measurement, and model construction, complementing each other and advancing the research onSOM dynamics. Existing and emerging … Read more
