Theses, Dissertations and Capstones
Soil nitrogen (N) dynamics have been shown to be quite sensitive to the soil hydrology. Creation of a mitigation freshwater wetland from an old field provided an opportunity to examine changes in N dynamics in terrestrial, aquatic (but formerly terrestrial), and transition (seasonally inundated) soils.
This thesis determined N availability using in situ incubations of soils taken from three distinct habitat conditions based on the degree of inundation following wetland creation: (1) old field (no inundation), (2) transition (seasonally inundated, initially beneath 10-20 cm of water), and (3) mitigation wetland (permanently inundated). Sample plots were located along five parallel transects …
