PEVELY SERIES
The Pevely series consists of moderately deep, moderately well drained, moderately rapidly permeable soils that formed in residuum weathered from sandstone. These soils are on hillslopes. Slopes range from 3 to 40 percent. Mean annual temperature is 55 degrees F, and mean annual precipitation is about 37 inches.
TAXONOMIC CLASS: Fine-loamy, mixed, active, mesic Oxyaquic Hapludalfs
TYPICAL PEDON: Pevely loam - on an east facing convex sideslope of 30 percent slope in deciduous timber at an elevation of 600 feet. (Colors are for moist soil unless otherwise stated.)
Oi--0 to 1 inches, partially decomposed leaves, twigs, and roots.
A--1 to 5 inches; dark brown (7.5YR 3/2) loam; brown (7.5YR 5/2) dry; weak very fine granular structure; very friable; common very fine and fine roots, and common medium and coarse roots; common very fine and fine interstitial pores; moderately acid (pH 5.6); clear smooth boundary. (1 to 6 inches thick)
E--5 to 11 inches; yellowish brown (10YR 5/4) loam; weak fine prismatic structure parting to weak very fine subangular blocky; friable; common very fine and fine roots, and common medium and coarse roots; common very fine and fine interstitial pores; very few distinct skeletans (sand or silt) in root channels and pores; strongly acid (pH 5.1) clear smooth boundary. (0 to 8 inches thick)
Bt1--11 to 15 inches; strong brown (7.5YR 4/6) sandy clay loam; moderate fine subangular blocky structure; firm; common very fine and fine roots, and common medium and coarse roots; few very fine and fine interstitial and tubular pores; very few distinct clay films on faces of peds; strongly acid (pH 5.1); clear wavy boundary.
Bt2--15 to 24 inches; strong brown (7.5YR 5/6) sandy clay loam; moderate medium subangular blocky structure parting to weak fine subangular blocky; firm; common very fine and fine roots; few very fine and fine interstitial and tubular pores; very few distinct clay films on faces of peds; strongly acid (pH 5.1); clear wavy boundary.
Bt3--24 to 33 inches; strong brown (7.5YR 5/6) parachannery sandy clay loam; moderate medium subangular blocky structure; firm; common very fine and fine roots; few very fine and fine interstitial and tubular pores; very few distinct clay films on faces of peds; few fine prominent grayish brown (10YR 5/2) iron depletions; common fine distinct black iron and manganese stains; 20 percent sandstone parachanners; very strongly acid (pH 5.0); clear wavy boundary. (Thickness of the Bt horizon ranges from 15 to 30 inches.)
C--33 to 38 inches; reddish yellow (7.5YR 6/8) very parachannery fine sand; single grain; loose; few very fine and fine roots; few very fine and fine interstitial and tubular pores; few fine prominent grayish brown (10YR 5/2) iron depletions; common fine distinct iron and manganese accumulations; 50 percent sandstone parachanners; very strongly acid (pH 4.9); clear smooth boundary. (0 to 8 inches thick)
R--38 inches; sandstone
TYPE LOCATION: Jefferson County, Missouri, about 1,050 feet due west of the Black Madonna Shrine; 810 feet south and 2,385 feet west of the northeast corner of section 4, T. 42 N., R. 3 E; USGS Pacific, Missouri quadrangle, 38 degrees, 24 minutes, 47.3 seconds north latitude, 90 degrees, 41 minutes, 32.2 seconds west longitude; UTM zone 15, UTM 701,482 m. easting and 4,254,178 m. northing, NAD 83.
RANGE IN CHARACTERISTICS: Depth to the lithic contact is 20 to 40 inches. The mean annual soil temperature at 20 inches is 55 to 59 degrees F.
The A horizon has hue of 10YR or 7.5YR, value of 3 or 4 and chroma of 2 to 4. It is loam or silt loam. Reaction is strongly acid to neutral.
The E horizon has hue of 10YR or 7.5YR, value of 4 to 6 and chroma of 2 to 5. It is loam, fine sandy loam, or silt loam. Reaction is strongly acid to neutral.
The Bt horizon has hue of 10YR to 5YR, value of 4 to 6, and chroma of 3 to 8. The fine earth is fine sandy loam, sandy clay loam, clay loam, or loam. The lower Bt has up to 35 percent parachanners. Reaction is very strongly acid to neutral. Mottles are in shades of red, brown, or gray.
The C horizon, where present, has hue of 10YR to 2.5YR, value of 4 to 6, and chroma of 3 to 8. Texture of the fine earth is loamy sand, sand, sandy loam, fine sandy loam, or loam and has 35 to 60 percent parachanners. Mottles are in shades of red, brown, or gray. Some pedons have a thin Cr horizon immediately above the hard bedrock contact.
COMPETING SERIES: These are the Adamstoen,
Beech,
Cazenovia,
El Dara,
Funkstown,
Hilton,
Kidami,
Lima,
Miami,
Rainsville,
Rawson,
Richland, Royertown,
Shawtown,
Summitville, and
Vaughnsville series. All of these soils except the Cazenovia and Summitville series are deeper than 60 inches to a lithic or paralithic contact. The Cazenovia and Summitville soils are deeper than 40 inches to a lithic or paralithic contact.
GEOGRAPHIC SETTING: Pevely soils are on ridgetops and sideslopes of hills. Slopes range from 3 to 40 percent. These soils formed in residuum weathered from sandstone. The mean annual temperature ranges from 53 to 57 degrees F, and annual precipitation ranges from 32 to 44 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Holstein,
Minnith, and
Ramsey series. Holstein soils are deeper than 60 inches to sandstone bedrock. Minnith soils have 20 to 40 inches of loess and are greater than 60 inches to sandstone bedrock. Ramsey soils are less than 20 inches to sandstone bedrock. All are on landscape positions similar to the Pevely series.
DRAINAGE AND PERMEABILITY: Moderately well drained. The surface runoff index is high to very high. Permeability is moderately rapid. The saturated hydraulic conductivity is moderately high. A water table is perched immediately above the bedrock contact for brief periods in late winter and early spring.
USE AND VEGETATION: Most areas remain in native hardwood timber, some areas are cleared for pasture or hay. Native vegetation is mixed grasses and hardwood deciduous trees.
DISTRIBUTION AND EXTENT: Pevely soils are mapped in the eastern part of the Ozark Highlands area (MLRA 116A) of central and southeast Missouri. The series is of moderate extent.
