DRIFTWOOD SERIES

The Driftwood series consists of very deep, poorly drained on flood plains. They formed in clayey over loamy alluvium. Slopes range from 0 to 1 percent. Mean annual precipitation is about 1067 mm (42 inches) and mean annual temperature is about 12 degrees C (53 degrees F).

TAXONOMIC CLASS: Fine, mixed, active, acid, mesic Fluvaquentic Endoaquepts

TYPICAL PEDON: Driftwood clay loam - on a nearly level area in a cultivated field at an elevation of about 165 meters (540 feet) above MSL. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 20 cm (0 to 8 inches); brown (10YR 5/3) clay loam, light gray (10YR 7/2) dry; weak coarse and medium subangular blocky structure; firm; many fine distinct gray (10YR 6/1) iron depletions and common fine distinct yellowish brown (10YR 5/6) masses of iron accumulations in the matrix; 2 percent fine gravel; strongly acid; abrupt smooth boundary. (20 to 30 cm or 8 to l2 inches thick)

Bg1--20 to 51 cm (8 to 20 inches); light gray (10YR 7/1) sandy clay loam; moderate coarse and very coarse prismatic structure parting to moderate coarse angular blocky; firm; many medium and coarse prominent strong brown (7.5YR 5/8) and common medium distinct light yellowish brown (10YR 6/4) masses of iron accumulations in the matrix; common faint light gray (10YR 7/1) clay depletions on faces of peds; 4 percent fine gravel; very strongly acid; gradual wavy boundary.

Bg2--51 to 91 cm (20 to 36 inches); light gray (10YR 7/1) clay; moderate coarse and very coarse prismatic structure parting to moderate coarse angular blocky; very firm; many medium and coarse prominent strong brown (7.5YR 5/8) and common medium distinct light yellowish brown (10YR 6/4) masses of iron accumulations in the matrix; common faint light gray (10YR 7/1) clay depletions on faces of peds; 2 percent fine gravel; strongly acid; gradual wavy boundary.

Bg3--91 to 160 cm (36 to 63 inches); gray (10YR 6/1) clay; moderate coarse and very coarse prismatic structure parting to moderate coarse angular blocky; very firm; many medium prominent strong brown (7.5YR 5/6) masses of iron accumulations in the matrix; common faint gray (10YR 6/1) clay depletions on faces of peds; common medium black (N 2.5/) iron and manganese concretions; 4 percent fine gravel; strongly acid; gradual wavy boundary. (Combined thickness of the Bg horizons is 112 to 147 cm or 44 to 58 inches)

Cg--160 to 203 cm (63 to 80 inches); gray (10YR 6/1) clay loam with thin strata of silty clay loam; massive; firm; many common prominent yellowish brown (10YR 5/6) masses of iron accumulations in the matrix; common medium black (N 2.5/) iron and manganese concretions); l0 percent fine gravel; neutral.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Driftwood soils are on broad, nearly level flood plains. The slope gradient is 0 to 1 percent. These soils formed in clayey over loamy alluvium. Mean annual precipitation is about 965 to 1118 mm (38 to 44 inches), and mean annual temperature is about 10 to 13 degrees C (50 to 55 degrees F). Frost free period is 170 to 190 days, and elevation ranges from 530 to 550 meters (1739 to 1804 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the somewhat poorly drained Stendal and Whitaker soils. These soils are on slightly higher rises on the flood plain.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained. Saturated hydraulic conductivity is moderately low or moderately high (0.42 to 1.41 micrometers/s). Permeability is slow. The potential for surface water runoff is negligible. The soil is subject to frequent, brief periods of flooding. An intermittent apparent seasonal high water table ranges from a depth of 30 cm (12 inches) above the soil surface to 30 cm (12 inches) below the soil surface from December through April in a normal year.

USE AND VEGETATION: Most areas of the Driftwood soils are used for cultivated crops, primarily corn and soybeans. Native vegetation is mixed hardwoods with elm, sycamore, and soft maple being the major species.

DISTRIBUTION AND EXTENT: South-central Indiana. Series is of small extent in MLRA 114A.

REMARKS: Diagnostic horizons and features recognized in this pedon are: 1) Ochric epipedon: the zone from 0 to 20 cm (0 to 8 in), (Ap horizon); 2) Cambic horizons: the zone from 20 to 160 cm (8 to 63 in), (Bg1, Bg2, Bg3 horizons). The classification of this series has changed from Fluvaquents to Endoaquepts.
