All hydric, but still vary
Availability of organics
When Oxygen is depleted, oxidized conditions occur
Causes the soil to be red-brown
Reduced soil is grey-blue
Oxidized soil layer can sometimes form but depends on several factors:
Transportation rate of O2 between the surface water and the atmosphere
Production of oxygen by algae
Number of oxygen consuming organisms in residence
The amount of surface mixing that occursRedox Reactions
Temporal changes and spatial variation of soil oxygen consumption, nitrification, and dentrification rates in a tidal salt marsh of the Lagoon of Venice, Italy.
P.G. Eriksson, J.M. Svensson, and G.M. Carrer
Estuarine, Coastal, and Shelf Science
To determine seasonal and spatial patterns of O2 in marsh soil, along with patterns of nitrification, dentrification, and flux of dissolved inorganic nitrogen (DIN)
Lagoon of Venice, Italy
540 square kilometers
Lagoon surrounded by tidal salt marsh
Study conducted in salt marsh on west side of lagoon
Tests conducted April-October of 1999
