KINDER SERIES

The Kinder series consists of very deep, poorly drained soils. These nearly level coastal prairie soils formed in loamy alluvium of late Pleistocene age or in loamy deltaic sediments over Pleistocene age terraces. Slopes range from 0 to 1 percent. Mean annual air temperature is about 19.5 degrees C (67 degrees F), and mean annual precipitation is about 1549 mm (61 in).

TAXONOMIC CLASS: Fine-silty, siliceous, active, thermic Typic Glossaqualfs

TYPICAL PEDON: Kinder silt loam--cropland. (Colors are for moist soil unless otherwise stated.)

COMPETING SERIES: These are the Alikchi (OK), Caddo (LA), Caneyhead , Evadale (TX), and Guyton (TX) series. Similar soils are the Basile (TX), Camptown(TX), Frost (LA), and Leton (TX) series.
Alikchi soils: paralithic contact with fractured shale between 51 and 102 cm (20 and 40 in).
Basile soils: mixed mineralogy; subhorizons that contain carbonate concretions.
Caddo soils: 1 to 5 percent plinthite in subhorizons of the B horizon.
Camptown soils: SAR of 4 to 12 at the Bt/E and Bt horizon contact; clayey lower layers.
Caneyhead soils: very poorly drained; a glossic horizon extending deeper than 203 cm (80 in). Evadale soils: underlain with 2Btg horizons that have 35 to 45 percent clay content: have SAR of 4 to 12 in the lower part.
Frost and Guyton soils: do not have red iron accumulations in the Bt horizon; Frost soils have mixed mineralogy. Leton soils are in slightly wetter stream meander depressions and do not have red iron accumulations.

GEOGRAPHIC SETTING:
Parent material: loamy fluviomarine deposits of Pleistocene age
Landscape: coastal plains
Landform: flats
Slope: 0 to 1 percent
Soil Moisture: An aquic soil moisture regime
Mean annual soil temperature: 19.9 to 21.7 degrees C (67 to 71 degrees F)

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Acadiana (LA), Basile (LA), Brimstone (LA), Crowley (LA), Glenmora (LA), Guyton (LA), Iota (LA), Kaplan (LA), Leton (TX), Messer(LA, and Vidrine(LA) soils. Acadiana, Iota, and Kaplan soils: on sideslopes at lower elevations; have a fine-textured control section. Basile and Guyton soils: on floodplains and drainageways.
Brimstone and Leton soils: lower in the landscape; do not have red masses of iron accumulation. Crowley soils: on higher landscape positions; an abrupt texture change; a fine textured control section. Glenmora soils : on sideslopes at lower elevations; moderately well drained; have higher chroma B horizons.
Messer and Vidrine soils: better drained; on mounds or smoothed mound areas.

DRAINAGE AND PERMEABILITY: Kinder soils are poorly drained. Runoff is high. Permeability is slow. A perched seasonal high water table is at a depth of 0 to 2 feet below the surface from December through April.

USE AND VEGETATION: Mainly used as cropland. Some areas are used as pasture or woodland. Rice and soybeans are the main crops grown. Water oak, sweetgum, sweet bay, loblolly, slash, and longleaf pines are dominant on areas where trees have encroached.

DISTRIBUTION AND EXTENT: Southwest Louisiana; LRR T; MLRA 152B. The soils of this series are moderately extensive

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Temple, Texas

SERIES ESTABLISHED: Allen Parish, Louisiana; 1978.

REMARKS: These soils are mapped in the transitional zone between the Coastal Prairie and Forested Coastal Plains. They were previously included with the Crowley and Caddo series. The series was updated during the Soil Data Join and Recorrelation initiative.
Diagnostic horizons and features recognized in this pedon are:

Ochric epipedon-0 to 43 cm (0 to 17 in) (Ap and Eg horizon)
Glossic horizon-43 to 58 cm (17 to 23 in) (Btg/E horizon)
Argillic horizon-43 to 99 cm (17 to 39 in ) (Btg/E, Btg horizons)

ADDITIONAL DATA: NSSL data from Acadia Parish, LA (S93LA-001-19).
