Healthy soils for sustainable agriculture: the role of SOM
3–7 September 2017 • Rothamsted Research • Harpenden (United Kingdom)

Deep soils are an important mineral nutrient reservoir, as well as a potential support for additional soil C storage. They are characterized by extremely low carbon contents and contrasting environmental conditions as compared to topsoil. Therefore, microbial and faunal life in deep soil is distinct, showing lower total biomass, diversity, activity and completely different community structures as compared to topsoil. This session addresses these differences and examines the plant and microbial interactions in deep soil, which may be contrasting to the ones observed in topsoil. Contributions addressing the biological origin of heterogeneity of deep soil and microbial life in hotspots are welcome. Moreover, we invite contributions about deep soil biology and their ability to deal with the contrasting conditions and their reaction to disturbance.
