3D characterization of the subsurface redox architecture in complex geological settings

Nitrogen (N) leaching caused by agricultural activities is one of the major threats to the aquatic ecosystems and public health. Moving from the agricultural soils through the subsurface and reemerging to the surface water, N undergoes various biogeochemical reactions along pathways in the subsurface, which occur heterogeneously in space and time. Thus to improve our understanding on the fate and distribution of N in the aquatic environment,...
