Direct and indirect effects of soil organic matter stability, plant, soil and microbial properties on the priming effect. The structural equation modelling was conducted for two forms of priming effect:aabsolute priming intensity;brelative priming intensity. Single-headed arrows indicate the hypothesized...

An important process by which soil fauna can influence the chemistry and stability of SOM is the ingestion of mineral particles and/or litter/organic matter, partial digestion in the gut, and egestion of the altered material as feces (Fig. 2). Depending on the ingested material, taxon and ...
Soil organic matter (SOM) plays a central role in the global carbon balance and in mitigating climate change. It will therefore be important to understand
organic matter, mineral-associated organic matter – that differ based on their chemistry, origin and stability over time (Kögel-Knabner and Rumpel, 2018;von Lützow et al., 2007). Whilst soil organic matter contains around 50% carbon (C) (Pribyl, 2010), it also contains high levels of...
