Wildfires induce physical and chemical alterations on soil properties, affecting both the quantity and composition of soil organic matter (SOM), and transforming biomass and SOM into pyrogenic carbon (PyC), also known as black carbon. PyC can derive from natural (e.g., wildfire charcoal), as well as anthropogenic sources (e.g., biochar) and it is recognized as important carbon sink in terrestrial and aquatic systems.
Wildfires and PyC can influence physical-, chemical-, and microbial soil functions by: changing composition and properties of native SOM which can modify soil physical properties (e.g. texture, structure, and moisture), changing redox- and pH conditions, and forming aggregates by mineral surface interaction of PyC micro- and nanoparticles. These changes can impact nutrient cycling and plant productivity, pollutant mobility, the soil microbiome, and edaphic fauna. These processes are of high importance for soil biochemistry, functioning, and carbon cycling, and to assess the environmental impact of wildfires for generating predictive tools that can be useful for post-fire restoration actions. To better understand the effects of Wildfires and PyC on soil, a wider knowledge of the abovementioned interlinked processes is urgently needed.
This session aims to bring together monodisciplinary as well interdisciplinary research on wildfire- and PyC-soil biochemistry, and carbon cycling, including studies on the alterations, impacts and cause-effect relationships induced by fire on SOM, as well as on describing recent advances on analytical techniques in the field. It welcomes submissions from lab- to field scale experiments as well as modelling, or meta-analytical approaches. Early career researchers and underrepresented groups in the field are strongly encouraged to apply.

How to access SSS5.9
Session SSS5.9 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
