PLUCK SERIES
The Pluck series consists of very deep, poorly drained soils that formed in loamy alluvial deposits of Holocene age. These soils are meandering channels of creeks and streams. Slope ranges from 0 to 1 percent but mainly less than 0.5 percent. Mean annual temperature is about 19.5 degrees C (67 degrees F), and mean annual precipitation is about 1422 mm (56 in).
TAXONOMIC CLASS: Fine-loamy, siliceous, active, acid, thermic Fluvaquentic Endoaquepts

Gowker soils: a mollic epipedon; on a higher position on the same landform
Hatliff soils: are better drained; on a higher position on the same landform
Kaman soils: are clayey throughout
Kian soils: are in a coarse-loamy family; on a similar landform
Nahatche soils: are somewhat poorly drained; on a higher position on the same landform
Voss soils: sandy throughout; bars adjacent to stream channels.
DRAINAGE AND PERMEABILITY: poorly drained. Runoff is high. A water table is at or near the surface during the winter and spring months. Frequently flooded for brief to long periods throughout normal years.
USE AND VEGETATION: Most areas of Pluck soils are mixed hardwood and pine cutover forest. A few areas have been cleared and are used for pasture of bahiagrass or improved bermudagrass.
DISTRIBUTION AND EXTENT: Southern coastal plains of southeast Texas and Louisiana. Land Resource Region T; MLRA 152B. The soils of this series are moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Polk and San Jacinto Counties, Texas; 1983.
REMARKS: Pluck soils were formerly included in the Nahatche or Mantachie series. The series was reclassified in 2013 as part of the update of MLRA 152B. The series type location was moved to Tyler County to a pedon that better represented the total series province.
Diagnostic horizons and features of this soil are:
Ochric epipedon -0 to 15 cm (0 to 6 in) (A horizons)
Cambic horizon- 15 to 203 cm (6 to 80 in) (Bg1, Bg2, Bg3, Bg4, Bg5 horizons)
There is an irregular distribution of organic carbon and the organic carbon is more than 0.2 percent.
The soil is saturated during the winter and spring seasons and has an aquic mosture regime.
ADDITIONAL DATA: Particle-size analysis and pH tests were performed at the project office on the series type location. Kellogg Soil Survey Laboratory data available on pedon S12TX373023 from a representative area in Polk County, Texas near the type location.
