TYPE LOCATION: Phelps County, Missouri; near Meramec springs: 1,350 feet north and 380 feet east of the southwest corner of sec. 33, T. 38 N., R. 6 W; USGS Meramec Springs, Missouri quadrangle, latitude 37 degrees 58 minutes 1.0 seconds N. and longitude 91 degrees 35 minutes 52.2 seconds W.; UTM zone 15, NAD 83, UTM 623,164 easting and 4,203,076 northing.
RANGE IN CHARACTERISTICS: In the upper 40 inches, rock fragment content by volume ranges from 0 to 35 percent for the 2mm to 3 inch size and from 0 to 5 percent for the larger than 3 inch size . Below 40 inches, rock fragment content by volume averages 0 to 35 percent gravel and from 0 to 10 percent cobbles, but individual horizons may contain more. The soil ranges from strongly acid to slightly alkaline.
The A horizon has hue of 7.5YR or 10YR, value of 3 or 4, and chroma of 2 to 4. It is sandy loam, loam, loamy fine sand, or fine sandy loam or their gravelly analogues.
The C horizon has hue of 5YR, 7.5YR, or 10YR, value of 3 to 6, and chroma of 2 to 6. It is stratified loamy fine sand, sand, sandy loam, fine sandy loam, loam, silt loam, loamy sand or their gravelly analogues. Very gravelly analogues may be present below a depth of 40 inches.
Buried A horizons are present in some places.
COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Kaintuck soils are on nearly level and gently sloping flood plains. Slope gradients range from 0 to 3 percent. The soils formed in loamy alluvium. Mean annual temperature ranges from 53 to 57 degrees F, and mean annual precipitation ranges from 42 to 46 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Midco, Razort and Relfe soils. Midco and Relfe soils are loamy-skeletal and are on similar positions. Razort soils are fine-loamy and are on terraces.
DRAINAGE AND PERMEABILITY: Well drained, low runoff; moderately rapid permeability. The saturated hydraulic conductivity is high. Kaintuck soils are subject to occasional to frequent flooding for very brief or brief durations.
USE AND VEGETATION: Most areas have been cleared. They are cropped to corn, sorghum, or soybeans or are used for hay or pasture. The remaining areas are in hardwood forest.
DISTRIBUTION AND EXTENT: The Ozarks Highlands region (MLRA 116A) of Missouri. The series is moderately extensive.
