SERIES PROPOSED: Gloucester County, New Jersey, 1999
REMARKS: New Jersey. Deptford soils were previously mapped in New Jersey as Barclay soils. Barclay soils are in a thermic temperature regime, lack argillic horizons, and are in a coarse-silty family. Recent particle-size analysis data from several pedons within 3 counties in New Jersey supports a coarse-loamy family. Deptford soils occur adjacent to landforms and soils with higher glauconite pellet content and sometimes contain few glauconite pellets mixed with the dominantly reworked marine materials from which the soils formed.
Diagnostic horizons and other soil characteristics recognized in this pedon are:
Ochric epipedon--the zone from the soil surface to a depth of 8 inches (Ap horizon)
Argillic horizon--the zone from a depth of 8 to 50 inches (Bt1, Bt2, Btg, and BCtg horizons)
Aquic conditions--the zone from 12 to 80 inches is periodically saturated (endosaturation)
Other soil features identified with this pedon:
Series control section--the zone from 0 to 60 inches
ADDITIONAL DATA:
Reference particle-size data is available from the project soil survey staff, Hammonton, New Jersey.
