JOLLY SERIES

The Jolly series consists of shallow soils over sandstone bedrock. These well drained, moderately permeable soils that developed in residuum and colluvium from sandstone. These soils are on gently sloping to strongly sloping uplands. Slopes range from 1 to 12 percent.

TAXONOMIC CLASS: Loamy, siliceous, active, thermic, shallow Typic Haplustalfs

TYPICAL PEDON: Jolly fine sandy loam--Rangeland. (Colors are for dry soil unless otherwise stated.)

A--0 to 5 inches; brown (7.5YR 5/4) fine sandy loam, brown (7.5YR 4/2) moist; weak medium subangular blocky structure parting to moderate medium granular; loose, very friable; many fine and medium roots; sandstone fragments up to 36 inches across cover about 5 percent of the surface; neutral; abrupt smooth boundary. (2 to 9 inches thick)

Bt--5 to 11 inches; reddish brown (5YR 5/4) sandy clay loam, reddish brown (5YR 4/3) moist; moderate coarse prismatic structure parting to moderate medium subangular blocky; very hard, very firm; many fine and medium roots; many fine and medium pores; common continuous clay films on surfaces of peds; slightly acid; clear smooth boundary. (3 to 14 inches thick)

Btc--11 to 18 inches, reddish brown (5YR 5/4) paragravelly sandy clay loam, reddish brown (5YR 4/4) moist; weak fine prismatic structure parting to moderate medium subangular blocky; hard, firm; many fine and medium roots; few medium pores; common thin patchy clay films on surfaces of peds; common medium black concretions; 30 percent discontinuous layers of soft sandstone parafragments less than 3 inches across; slightly acid; abrupt smooth boundary. (0 to 13 inches thick)

Cr--18 to 40 inches; pale yellow (5Y 7/3) weakly cemented sandstone bedrock, pale olive (5Y 6/3) moist; few coarse yellowish brown (10YR 5/8) mottles and streaks; common black streaks; neutral.

TYPE LOCATION: Archer County, Texas; from the intersection of Texas Highways 25 and 79 in Archer City; about 5.25 miles north on Texas Highway 79; 0.72 mile west northwest on a ranch road; then 75 feet south in rangeland. (Latitude:

RANGE IN CHARACTERISTICS: Solum thickness and depth to cemented sandstone bedrock ranges from 12 to 20 inches. The weighted average of coarse fragments in the solum ranges from none to about 30 percent. These are partially weathered sandstone pebbles, cobbles, or flagstones. Coarse fragments on the surface range from none to about 10 percent and from gravel to stone size with a few outcrops of sandstone bedrock.

The A horizon has hue of 5YR to 10YR, value of 4 or 5 and dominant chroma of 4. Texture is fine sandy loam, very fine sandy loam, or loam. Reaction ranges from moderately acid to neutral.

The Bt horizon has hue of 5YR or 7.5YR, value of 4 or 5 and dominant chroma of 4. Clay content ranges from 15 to 30 percent, but average clay content of the control section ranges from 20 to 30 percent. Discontinuous layers of soft sandstone parafragments less than 3 inches across range from 0 to 15 percent of the Bt horizon and from 10 to 45 percent by volume in the Btc horizon. Reaction is slightly acid or neutral.

The Cr layer is extremely weakly to moderately cemented, noncalcareous, horizontally layered sandstone. It has hue of 10YR to 5Y, value of 6 to 8 and chroma of 1 to 6. Coarse reddish and brownish mottles and black streaks are in some pedons. In some pedons the sandstone bedrock below a depth of 40 inches is strongly cemented or noncemented.

COMPETING SERIES: There are no other competing series. Similar soils include the Bluegrove, Bonti, Cobb, Cosh, Darnell, Dill, Exray, Latom, Nebgen, Oben, Pontotoc, and Quinlan series. Bluegrove, Bonti, Cobb, Dill, and Pontotoc have sola thicker than 20 inches. Cosh and Exray soils have argillic horizons redder than 5YR and moist values less than 4, and in addition, the Exray soils have a clayey control section. Darnell, Latom, Nebgen, and Quinlan soils do not have an argillic horizon. Oben soils formed in glauconitic sandstones, have mixed mineralogy, and significantly different native vegetation.

GEOGRAPHIC SETTING: Jolly soils are on gently sloping to strongly sloping, plane or convex ridges and plains. slopes range from 1 to 12 percent. The soil formed in fine and medium grained residuum and colluvium derived from sandstone of Permian and Pennsylvanian age. Mean annual precipitation ranges from 26 to 30 inches, the mean annual temperature ranges from 63 to 66 degrees F. Frost free days range from 210 to 240, and elevation ranges from 1,050 to 1,600 feet. Thornthwaite annual P-E indices ranges from 40 to 44.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bluegrove, Cobb, Darnell, Grandfield, Owens, Throck,and Vernon series. Bluegrove and Cobb soils are higher on ridgetops. Grandfield soils have sola greater than 60 inches, are not underlain by sandstone, and are on lower toeslopes. The clayey Owens, Throck, and Vernon soils are on midslopes and footslopes below sandstone outcrops.

DRAINAGE AND PERMEABILITY: Well drained. Permeability of the soil is moderate above a moderately slowly permeable bedrock. Runoff is very low on 1 to 3 percent slopes, low on 3 to 5 percent slopes, medium on 5 to 10 percent slopes, and high on slopes greater than 10 percent.

USE AND VEGETATION: The principal use is for rangeland. Small acreage has been cultivated in the past but most cultivated areas are now abandoned and returned to rangeland. Native vegetation is mainly little bluestem, sand bluestem, cane bluestem, sideoats grama, vine-mesquite, Arizona cottontop, Texas wintergrass, Wrights threeawn, blue grama and sand dropseed. Mesquite and prickly pear have invaded most areas.

DISTRIBUTION AND EXTENT: North and North-central Texas; and possibly in southwestern Oklahoma. Most of these soils are across the Central Rolling Red prairies, the northeast part of the Central Rolling Red Plains, and northeastern Texas North Central Prairies. Jolly soils are of moderate extent.

MLRA OFFICE RESPONSIBLE: Temple, Texas

SERIES ESTABLISHED: Archer County, Texas; 1984.

REMARKS: Jolly soils were formerly included in the Oben series which occurs in Cambrian sandstone in the Central Basin (MLRA 82) of Texas.
