SSS2.2Advances in understanding the role of soil aggregate stability for soil functions
|Convener: Barry Rawlins | Co-Conveners: Jorge Mataix-Solera , Jay Jabro|
It has been argued that aggregation (and the formation of soil aggregates) is one of the three unique aspects of soil science. The stability of soil aggregates is of critical importance for a range of soil functions or
degradation threats including carbon storage, hydrology and erosion. The importance of structure, rather than recalcitrance, in controlling carbon
preservation in soil also suggests that aggregate structure and turnover plays a vital role in carbon storage. There is increasing interest in linking
the turnover of carbon and aggregates for modelling key soil processes.
We invite contributions on methods relating to the measurements of aggregate stability and aggregate hierarchies, their applications to understanding soil functions across different scales, and their inclusion in process-based models.
