Summary of the thematic day:


The sustainable management of element cycling, either nutrients or contaminants, in soil-plant systems requires the understanding of soil processes that govern the interactions between soil constituents, soil properties and functions. Soil processes strongly affect the rate of element cycling in terrestrial ecosystems but also the mineral and organic origin of the bioavailable pools of the elements. The management of agro-ecosystems is in a transition stage, given the challenge of producing more biomass while increasing the resistance and resilience of food systems. A process-based approach of the evolution of soil in a constantly varying environment is crucial in a further understanding of how soils can sustain the ecological equilibrium of agro-ecosystems.
