Soils are increasingly being looked to as a potentially important tool in our efforts to offset emissions and reduce our impacts on the global climate. However, such a concept is hotly contested. Here, the latest research assessing the opportunities and impacts of such strategies will be discussed.

The fact that SOM delivers multiple ecosystem services is well known. However, there remains a dearth of quantitative information on the value of these services to land managers, agriculture, and broader society, necessary in order to implement the UN SDGs. This session aims to draw together information that elucidates the short- and long-term value of SOM, and the impacts of building or losing this resource on society’s ability to meet the requirements of the SDGs.

SOM performs many ecosystem services in both natural and managed systems, yet mechanisms involved in its interaction with other biophysical processes such as nutrient cycling, water retention, structural stability remain difficult to fully elucidate. This session provides a forum in which research addressing these underlying questions, and the impacts they have on broader ecosystem processes can be presented.

Simulation models describing SOM dynamics have been around for decades, and perform roles at levels ranging from the molecular and microbial scale through to global carbon accounts and climate predictions. Recent advances in computing capacity, data availability, and our understanding of biophyiscal processes have led to huge leaps forward in our capability to model across scales. Here, we provide opportunity for recent advances in modelling and data sciences associated with SOM research to be presented.
