REMARKS:
Diagnostic horizons and features recognized in this pedon are:
Particle size control section: 48 to 99 cm (19 to 39 in). (Btg/Eg1 and Btg/Eg2 horizons)
Ochric epipedon: 0 to 8 cm (0 to 3 in). (A horizon)

Glossic horizon: 48 to 203 cm (19 to 80 in). (Btg/Eg1, Btg/Eg2, Btg/Eg3, Btg/Eg4 horizons)
Other features:
Vermic feature: 8 to 48 cm (3 to 19 in), 50 percent or more or crawfish bioturbation (Bg horizons)
Aquic conditions: These soils remain saturated and have aquic conditions from November to April from the surface to 30 cm (1 ft) in most years.
Additional Comments: The classification was changed in April 2000 from Typic Vermaqualfs to Natric Vermaqualfs due to lab data from the series type location from Hardin County, Texas. A study of salinity levels was conducted on this and other soils to determine the amount of seasonal variability. During the wetter time of year, ESP levels are typically 1 to 3 points lower than the drier time.
The assignment of the cation-exchange activity class is supported by laboratory data number (S96TX-199-008) from series type location in Hardin County, Texas.
ADDITIONAL DATA: Data available from Texas A&M University (TAMU) Soil Characterization Lab on sample (S96TX-199-008) from the series type location in Hardin County, Texas. NSSL data from salinity study on lab samples 02N0323,02N0324, and 02N0325. Additional data from TAMU on sample S00-TX241-002 from Jasper County.
