COMPETING SERIES: None
GEOGRAPHIC SETTING:
Landscape: Coastal Plain
Landform: Flood plains
Elevation: 0 to 20 feet
Parent Material: Loamy fluvial sediments underlain by highly decomposed organic material, dominantly from woody plants
Mean Annual Air Temperature: 52 to 58 degrees F.
Mean Annual Precipitation: 24 to 48 inches
Frost Free Period: 190 to 210 days
GEOGRAPHICALLY ASSOCIATED SOILS:
Fallsington soils--have a fine-loamy particle-size control section and an argillic horizon, on slightly higher positions
Hurlock soils--have a coarse-loamy particle-size control section and an argillic horizon, on slightly higher positions
Pone soils--have an umbric epipedon and an argillic horizon, on slightly higher positions
Puckum soils--have organic soil materials from the surface to more than 51 inches, on slightly lower-lying landforms
