High Resolution Assessment of Spatio-Temporal Changes in O Concentration in Root-Pathogen Interaction.

Fusarium wilt, caused by the fungus f. sp. , is one of the most destructive soil-borne diseases of tomatoes.

Universal scaling-law for flow resistance over canopies with complex morphology.

Flow resistance caused by vegetation is a key parameter to properly assess flood management and river restoration. However, quantifying the friction factor or any of its alternative metrics, e.g.

2D visualization captures the local heterogeneity of oxidative metabolism across soils from diverse land-use.

Fine-scale processes in soils affect large-scale phenomena by controlling mixing and reaction rates, yet technological constraints have hampered the collection of micro-scale kinetic data. As a result, limited information is available on the magnitude of fine-scale biogeochemical rates and their temporal and spatial pattern in response to environmental perturbations. In this work we investigate the spatio-temporal dynamics in oxidative microbial activity and the development of anoxic micro zones (i.

Hydrologic control on redox and nitrogen dynamics in a peatland soil.

Soils are a dominant source of nitrous oxide (N(2)O), a potent greenhouse gas. However, the complexity of the drivers of N(2)O production and emissions has hindered our ability to predict the magnitude and spatial dynamics of N(2)O fluxes. Soil moisture can be considered a key driver because it influences oxygen (O(2)) supply, which feeds back on N(2)O sources (nitrification versus denitrification) and sinks (reduction to dinitrogen).
