Extent: Small
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: RALEIGH, NORTH CAROLINA
SERIES ESTABLISHED: Queen Anne's County, Maryland, 1995.
REMARKS: Corsica soils were formerly included in the Pocomoke series. It is distinguished from Pocomoke by having more than 18 percent clay in the particle size control section, and having a mesic temperature class.
Diagnostic horizons and other diagnostic soil characteristics recognized in this pedon are:
Umbric epipedon--the zone from 5 to 30 cm (A horizon)
Argillic horizon--the zone from 46 to 102 cm (Btg1 and Btg2 horizons)
Aquic conditions--the zone from 5 cm to a depth of 203 cm is periodically saturated (endosaturation)
