GLENVILLE SERIES
The Glenville series consists of very deep moderately well drained or somewhat poorly drained soils. They formed primarily in colluvium or residuum affected by soil creep that is weathered from phyllite, micaceous schist, granitic gneiss and other acid crystalline rocks. Slopes range from 0 to 15 percent. Saturated hydraulic conductivity is moderately low to moderately high. Mean annual precipitation is 1145 mm (45 inches). Mean annual temperature is 10 degrees C (51 degrees F).
TAXONOMIC CLASS: Fine-loamy, mixed, active, mesic Aquic Fragiudults

(0 to 40 centimeters thick)
BC--33 to 39 inches, yellowish brown (10YR 5/4) silt loam; weak coarse subangular blocky structure parting to weak medium subangular blocky; firm, slightly sticky and slightly plastic; many faint pale brown (10YR 6/3) iron depletions on vertical faces of peds; 10 percent quartzite channers common fine mica flakes; moderately acid; gradual wavy boundary.
C--39 to 82 inches; yellowish brown (10YR 5/4) channery loam; massive; friable, nonsticky and nonplastic; many prominent strong brown (7.5YR 5/8) masses of oxidized iron on vertical faces of peds and common distinct grayish brown (10YR 5/2) iron depletions on vertical faces of peds; many fine mica flakes; 15 percent quartzite channers; moderately acid.
TYPE LOCATION: Chester County, Pennsylvania; Franklin Township, 4000 feet southeast of Kemblesville, 1600 feet south of Pennsylvania 896, 128 feet east of farm lane; 130 feet east southeast of first pole north of pasture. USGS Newark West Quadrangle; Lat. 39 degrees, 44 minutes, 33 seconds North and Long. 75 degrees, 48 minutes, 47 seconds West.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 30 to 40 inches. Depth to bedrock is more than 60 inches. Depth to the fragipan is 15 to 30 inches. Rock fragments of phyllite, schist, gneiss or quartzite generally increase with depth, ranging from 0 to 30 percent in the solum and from 5 to 80 percent in the C horizon. Some pedons have flakes of mica that generally increases with depth. Reaction is neutral to very strongly acid in the A horizon, moderately acid to very strongly acid in the B horizon, and moderately or very strongly acid in the C horizon.
The A horizon has hue 10YR or 2.5Y, value 3 to 5 and chroma 2 to 6. It is silt loam, loam or fine sandy loam in the fine earth.
The Bt horizon has hue 10YR or 7.5YR, value 4 to 6 and chroma 3 to 8. Low chroma redoximorphic features are within the upper 10 inches of the argillic horizon. Texture is silt loam, clay loam, or silty clay loam in the fine earth.
The Btx or Btgx horizons have hue 10YR or 7.5YR, value 4 to 6 and chroma 2 to 6. Texture of the fine-earth material is loam or silt loam. Consistence is firm or very firm and brittle.
The BC or BCg horizons have the same color and texture as the Btx or Btgx horizon.
The C or Cg horizons have hue 2.5YR to 10YR, value 4 to 6 and chroma 1 to 8. Fine earth texture is loam, sandy loam, or fine sandy loam.
COMPETING SERIES: The
Cookport,
Kedron and
Raritan series in the same family. Cookport soils are deep and very deep, formed in residuum weathered from sandstone and occur on the unglaciated
Allegheny Plateau. Kedron soils are very deep, are formed in colluvium or glacial till from reddish shale, siltstone, and fine-grained sandstone and typically have hues of 2.5YR or redder in the solum. Raritan soils are very deep and formed in alluvium from red shale, siltstone and sandstone and contain rounded rock fragments and stratified sand, silt and gravel.
GEOGRAPHIC SETTING: The Glenville soils are nearly level to strongly sloping soils on upland flats, footslopes or near the heads of drainageways. Slopes range from 0 to 15 percent. The Glenville soils have developed in residuum or colluvium affected by soil creep that is weathered from phyllite, micaceous schist, gneiss and other acid crystalline rocks. The climate is temperate and humid with average annual temperature of 48 degrees to 57 degrees F, and average annual precipitation of about 40 to 50 inches. The growing season ranges from about 160 to 200 days.

Highfield,
Linganore,

Mt. Airy,
Neshaminy,
Nason,
Parker,
Relay,
Tatum,
Towhee and
Urbana soils. All of these soils, except the Towhee and Urbana soils, do not have a fragipan. Towhee and Urbana soils have more than 35 percent base saturation.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained or somewhat poorly drained depending on depth to the fragipan. Runoff is negligible to very high. Saturated hydraulic conductivity is moderately high to high above the fragipan, moderately low to high in the fragipan, and moderately high below the fragipan.
USE AND VEGETATION: General crops but mostly grain, hay and pasture. Native vegetation consists of mixed hardwoods. Sizable areas are adjacent to community development and urban expansion.
DISTRIBUTION AND EXTENT: MLRA 148 Northern Piedmont. Southeastern Pennsylvania, Delaware, Maryland, New Jersey, and northern Virginia. The series is extensive.

REMARKS: Diagnostic horizons recognized in this pedon are:
a. Ochric epipedon - the zone from the surface to a depth of 9 inches (Ap horizon).
b. Argillic horizon - the zone from 9 to 19 inches (Bt1 and Bt2 horizons).
c. Fragipan the zone from 19 to 33 inches (Btx and Btgx horizons).
d. Aquic conditions the zone from 16 to 33 inches (Bt2, Btx, and Btgx horizons).
1992: Revised to reflect depth to bedrock range of more than 60 inches.
2003: Type location relocated and series concept modified to reflect a shift from pure residuum to either colluvium or, at a minimum, residuum affected by soil creep. Former type location did not have redoximorphic features described above the fragipan.
2008: Pedon description and site location updated
