DESCRIPTION:Soil structure\, i.e.\, the spatial arrangement of minerals\, o
 rganic matter\, and pores\, is key to understanding various soil functions
 \, from water storage to carbon and nutrient cycling. The scientific commu
 nity\, however\, is still debating how to characterize soil structure\, ho
 w to quantify its impact on various functions\, and if and how soil struct
 ure should be considered in soil-plant-atmosphere models.\nIn this present
 ation\, I will introduce methodological developments based on X-ray comput
 ed tomography for quantifying structural indicators and their effects on s
 oil hydraulic properties and organic carbon turnover. Based on laboratory 
 and field experiments\, we were able to show that soil structure is altere
 d by the soil management system and is subject to seasonal  fluctuations d
 riven by abiotic and biotic factors. It affects water flow during evaporat
 ion\, carbon mobilisation and mineralization\, and provides physical prote
 ction for organic matter. In view of various soil physical challenges\, co
 nsidering spatial heterogeneity and their temporal dynamics in our studies
  increases the complexity of the soil system\, but when taken into account
 \, it offers an opportunity to adapt soil management to promote certain so
 il functions.
