TYPE LOCATION: Allen Parish, Louisiana; 0.5 mile northwest of Kinder; 300 feet north of Kinder Hospital; NE1/4NW1/4, sec. 35, T. 6 S., R. 5 W.
RANGE IN CHARACTERISTICS: Solum thickness is more than 80 inches. Reaction ranges from extremely acid to moderately acid in the A and E horizons, very strongly acid to slightly acid in the B/E and Btg horizon, and very strongly acid to moderately alkaline in the Bg and BCg horizons. Sand content, that is dominantly very fine sand in the control section, ranges from 15 to 40 percent.
The A or Ap horizon has hue of 10YR, value of 4 or 5, and chroma of 1 or 2. Texture is silt loam, loam, or very fine sandy loam.
The Eg and, where present, the E'g horizon has hue of 10YR, value of 5 or 6, and chroma of 1 or 2. Texture is silt loam, loam, or very fine sandy loam.
The B/E and Btg horizons have hue of 10YR to 5Y, value of 4 to 6, and chroma of 1 or 2. Red masses of iron in the upper Btg horizon range from common to many. Redox features in shades of brown or gray range from few to common. Texture is silt loam, loam, silty clay loam, or clay loam.
The Bg horizon and BCg horizon have hue of 10YR to 5Y, value of 5 or 6 and chroma of 1 or 2. Texture is silt loam, loam, or silty clay loam.
COMPETING SERIES: These are the Alikchi, Caddo, Caneyhead, Evadale, and Guyton series. Similar soils are the Basile, Camptown, Frost, and Leton series. Alikchi soils have a paralithic contact with fractured shale between 20 and 40 inches. Basile soils have mixed mineralogy and subhorizons that contain carbonate concretions. Caddo soils have 1 to 5 percent plinthite in subhorizons of the B horizon. Camptown soils have SAR of 4 to 12 at the Bt/E and Bt horizon contact and have clayey lower layers. Caneyhead soils are very poorly drained and have a glossic horizon extending deeper than 80 inches. Evadale soils are underlain with 2Btg horizons that have 35 to 45 percent clay content and have SAR of 4 to 12 in the lower part. Frost and Guyton soils do not have red iron accumulations in the Bt horizon. In addition, Frost soils have mixed mineralogy. Leton soils are in slightly wetter stream meander depressions and do not have red iron accumulations.
GEOGRAPHIC SETTING: Kinder soils are on coastal prairies of late Pleistocene age. Slope ranges from 0 to 1 percent. The soils formed in loamy alluvium mainly under grassland vegetation, however some areas have encroachment by trees. Mean annual temperature is 68 to 70 degrees F. Mean annual rainfall is 56 to 62 inches. Frost free days range from 235 to 300. Elevation ranges from 10 to 80 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Acadiana, Basile, Brimstone, Crowley, Glenmora, Guyton, Iota, Kaplan, Leton, Messer, and Vidrine soils. Acadiana, Iota, and Kaplan soils are on sideslopes at lower elevations and have a fine-textured control section. Basile and Guyton soils are on floodplains and drainageways. Brimstone and Leton soils are lower in the landscape and do not have red masses of iron accumulation. Crowley soils are on higher landscape positions have an abrupt texture change and a fine textured control section. Glenmore soils are on sideslopes at lower elevations, are moderately well drained, and have higher chroma B horizons. Messer and Vidrine soils are better drained and occur on mounds or smoothed mound areas.
DRAINAGE AND PERMEABILITY: Kinder soils are poorly drained. Runoff is low. 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 and possibly southeast Texas (MLRA 152B, LRR T). The soils of this series are moderately extensive.
MLRA OFFICE 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.
