Soil morphology and potentiometric surface relationship in an East Central Indiana toposequence
The objective of this study was to determine the correlation between potentiometric surface and the depth to selected soil morphological indicators of wetness for the Glynwood (Aquic Hapludalf), Blount (Aeric Epiaqulaf), and Pewamo (Typic Argiaguoll) soils in Delaware County, Indiana. Four years of...

| Summary: | The objective of this study was to determine the correlation between potentiometric surface and the depth to selected soil morphological indicators of wetness for the Glynwood (Aquic Hapludalf), Blount (Aeric Epiaqulaf), and Pewamo (Typic Argiaguoll) soils in Delaware County, Indiana. Four years of potentiometric surface measurements were averaged and compared to detailed soil descriptions performed by the Natural Resources Conservation Service. Significant correlations exist between the morphological indicators and the potentiometric surface for the Glynwood (moderately well drained) 2-m depth piezometers and 2-m depth slotted pipes, the Blount (somewhat poorly drained) top of the C horizon and 2-m depth piezometers, and the Pewamo (poorly drained) top of the B horizon piezometers. The relationships among the horizons in which potentiometric surface correlated to indicator depth may be a function of the increased persistence and shallowness of the potentiometric surface in mid-April. === Department of Natural Resources and Environmental Management |
