Bt horizon(s):
Hue: 2.5YR to 7.5YR
Value: 4 to 6
Chroma: 6 or 8
Redoximorphic features: range from none to common. Black and brown manganese concretions and masses range from none to many.
Texture: loam, clay loam, sandy clay loam, or very fine sandy loam. Rock fragments: ranges from none to 5 percent. Black and brown manganese concretions and masses range from none to many.
Btx horizon: Color: Typically variegated in shades of yellow, brown, gray, and red or has brown and red matrix colors with redoximorphic features in shades of gray, yellow, and red. Black and brown manganese concretions and masses range from few to many.
Texture: sandy clay loam, clay loam, loam, very fine sandy loam or fine sandy loam.
Rock fragments: ranges from none to 5 percent.
Other features: The matrix of the prisms is very firm when dry and brittle. It constitutes more than 65 percent of the volume.
COMPETING SERIES: These are the
Cane,
Ora,
Savannah,
Sidon, and
Wax series in the same family and the closely related
Bourne,
Irvington,
Leadvale,
Locust,
Paden,
Prentiss,
Providence,
Ruston, and
Smithdale series.
Cane soils have more than 5 percent by volume of chert or quartz gravel or both in some part of the solum.
Savannah and Wax soils have a Bt horizon in hue of 7.5YR or yellower.
Sidon soils have interbedded siltstone, shale, and sandstone at a depth ranging from 40 to 60 inches.
Bourne and Locust soils have mixed mineralogy and a strong brown to yellowish brown Bt horizon.
Irvington soils are yellowish brown in color, have double clay mixima, and have more than 5 percent plinthite within 60 inches of the surface.
Leadvale and Paden soils have less than 15 percent sand coarser than very fine sand in the Bt horizon. In addition, Paden soils have double clay mixima.
Prentiss soils have a coarse-loamy control section. Providence soils have a fine-silty control section and have base saturation of more than 35 percent.
Ruston and Smithdale soils do not have a fragipan.
GEOGRAPHIC SETTING: The Kizzia soils are on nearly level to strongly sloping interfluves with slopes ranging from 1 to 12 percent. The soil formed in loamy marine deposits on the Cretaceous Western Coastal Plain. The climate is warm and humid. The mean annual temperature is 60 degrees F., and the average annual precipitation is 48 to 63 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
McCaskill,
Nathan and
Tiak soils.
McCaskill soils are on similar landscapes, are somewhat poorly drained and do nto have a fragipan.
Nathan soils are on similar landscapes, are well drained and do not have a fragipan
Tiak soils are on similar landscapes but do not have a fragipan.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium to moderately rapid runoff. Permeability is moderate in the upper part of the solum and moderately slow in the fragipan. These soils have a perched water table at a depth of 61 tp 102 cm (24 to 40 in) during the months of high rainfall.
USE AND VEGETATION: Most areas of the Kizzia soils are used for hay and pasture or for woodland. Principal vegetation of wooded areas is loblolly pine or shortleaf pine or pines mixed with oaks, hickory, and sweetgum.
DISTRIBUTION AND EXTENT: Cretaceous Western Coastal Plain in Arkansas and possibly in Oklahoma. The series is of moderate extent.
