Divergent changes in particulate and mineral-associated organic carbon upon permafrost thaw. [PDF]

Nat Commun, 2022
Based on observations from thermokarst-impacted sites on the Tibetan Plateau, the authors find substantial particulate organic carbon loss but stable mineral-associated organic carbon and enriched iron-bound organic carbon upon permafrost thaw.

Stabilization of mineral-associated organic carbon in Pleistocene permafrost. [PDF]

Nat Commun, 2023
Ice-rich Pleistocene-age permafrost is particularly vulnerable to rapid thaw, which may quickly expose a large pool of sedimentary organic matter (OM) to microbial degradation and lead to emissions of climate-sensitive greenhouse gases.

Soil organic carbon fractions in different land use systems of Chernozem soil [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2020
The relationship between soil carbon fractions in Chernozem soils was assessed in soil samples of three different environments: arable soil, grassland and oak for­est. Grassland and oak forest had higher soil organic carbon (SOC), carbon soluble

Global stocks and capacity of mineral-associated soil organic carbon

Nature Communications, 2022
Mineral-organic associations play a key role in soil carbon preservation. Here, Georgiou et al. produce global estimates of mineral-associated soil carbon, providing insight into the world’s soils and their capacity to store ...

Forest management causes soil carbon loss by reducing particulate organic carbon in Guangxi, Southern China

Forest Ecosystems, 2023
Background: The loss of soil organic carbon (SOC) following conversion of natural forests to managed plantations has been widely reported. However, how different SOC fractions and microbial necromass C (MNC) respond to forest management practices remains

Simulated wild boar bioturbation increases the stability of forest soil carbon [PDF]

Biogeosciences, 2019
Most forest soils are characterised by a steep carbon gradient from the forest floor to the mineral soil, indicating that carbon is prevented from entry into the soil.

Carbon patterns and soil quality in fragile soils under sustainable soil management in organic systems of Southeastern Brazil: Short-term assessment [PDF]

Revista Brasileira de Ciência do Solo
Adopting conservationist soil use and management practices, such as the no-tillage system and cover crops associated with organic agriculture, can improve the quality of fragile soils.

Secondary shrubs promoted the priming effect by increasing soil particle organic carbon mineralization

Frontiers in Forests and Global Change, 2023
IntroductionInputs of additional organic matter to the soil will accelerate or inhibit the decomposition of soil organic carbon (SOC), resulting in a priming effect (PE), which is a key mechanism affecting soil carbon (C) cycling. The impact mechanism of

Persistent soil organic carbon deficits from converting primary forests to plantations and secondary forests in subtropical China

Global Ecology and Conservation, 2023
Soil organic carbon (SOC) plays a critical role in supporting key ecosystem functions and services for humanity. Despite the widespread conversion of primary forests to plantations and secondary forests, it remains uncertain how it affects the content ...

Visualizing Mineral-Associated Organic Matters in Long-Term Fertilization Treated Soils by NanoSIMS and SR-FTIR

Frontiers in Soil Science, 2022
Formation of mineral-associated organic matters is essential for long-term soil organic carbon preservation. However, the regulation pathways of mineral-associated organic matters in soils remains largely undescribed, especially at the submicron scale ...
