Life in soil hotspots: Microbial activity, carbon and nutrient cycling and functions
Convener: Minsu KimECSECS | Co-conveners: Yakov Kuzyakov, Stefanie MaierECSECS, Bettina Weber
Microbial hotspots in soils such as the rhizosphere, detritusphere, biopores, hyphasphere, aggregate surfaces and etc, are characterized by high activity and fast process rates resulting in accelerated turnover of soil organic matter and other microbial functions (e.g. nutrient mobilization, litter decomposition, respiration, organic matter stabilization, greenhouse gas emission, acidification, etc.). The intensity of microbial and SOM turnover as well as nutrient cycling in such hotspots is at least one order of magnitude higher than in the bulk soil.
This session invites contribution to: 1) Various aspects of microbial activity, interactions, communities composition and distribution in hotspots; 2) Factors influencing (micro)biological nutrient (re)cycling including biotic and abiotic controls are strongly encouraged; 3) The session will also present and discuss new developments to assess the crucial microbial mechanisms that underpin biogeochemical processes in hotspots (e.g. new approaches and imaging methods); 4) Combination of experimental and theoretical approaches to predict the fate and functions of microorganisms in hotspots are highly appreciated.
