QUEENY SERIES

The Queeny series consists of very shallow and shallow to a petrocalcic horizon, well drained soils that formed in calcareous loamy over gravelly alluvium derived from shale, claystone, siltstone, or chalk of Cretaceous Age. These nearly level to moderately steep soils are on treads of stream terraces on dissected plains. Slopes range from 1 to 20 percent. Mean annual precipitation is about 820.2 mm (32.29 in) and the mean annual air temperature is about 20.8 degrees C (69.4 degrees F).

TAXONOMIC CLASS: Loamy, mixed, superactive, thermic, shallow Petrocalcic Calciustolls

TYPICAL PEDON: Queeny gravelly loam--rangeland. (Colors are for dry soil unless otherwise stated.)

A--0 to 23 cm (0 to 9 in); very dark grayish brown (10YR 3/2) gravelly loam, very dark brown (10YR 2/2) moist; moderate fine and medium granular structure; hard, friable; common fine roots; about 15 percent siliceous pebbles; few limestone pebbles on surface and within horizon; calcareous, moderately alkaline; abrupt wavy boundary. (10 to 51 cm [4 to 20 in] thick)

Bkkm--23 to 43 cm (9 to 17 in); very pale brown (10YR 8/3) strongly cemented platy caliche containing common embedded siliceous and limestone pebbles; the caliche plates are mostly 10 to 38 cm (4 to 15 in) long and 3 to 5 cm (1 to 2 in) thick; few fine crevices and solution channels filled with very dark grayish brown loam in the upper plates; moderately alkaline; clear wavy boundary. (5 to 46 cm [2 to 18 in] thick)

Ck--43 to 94 cm (17 to 37 in); very pale brown (10YR 8/2) weakly cemented, massive caliche containing common embedded siliceous and limestone pebbles; moderately alkaline; clear wavy boundary. (51 to 244 cm [20 to 96 in] thick)

2C--94 to 366 cm (37 to 144 in); very gravelly sand composed of about 60 to 70 percent by volume of siliceous and limestone pebbles and 30 to 40 percent by volume of brownish yellow (10YR 6/6) and light gray (10YR 7/2) fine sand; pebbles are mostly 0.4 to 3 cm (0.125 to 1 in) in diameter; some of the fine sand is in interbedded layers that are 0.4 to 10 cm (0.25 to 4 in) thick and 5 to 15 cm (2 to 6 in) apart; loose; few soft bodies of calcium carbonate; calcareous, moderately alkaline.

COMPETING SERIES: These include the Carbine, Espy, Kimberson, Ozona, and Pitzer series in the same family and the similar Cho, Kavett, Mereta, Patrick, and Stephen series.
Carbine soils: occurs in an aridic ustic moisture regime.
Espy soils: have cambic horizons.
Kimberson soils: have an ustic moisture regime bordering on aridic.
Ozona soils: occurs in an aridic ustic moisture regime and does not have quartzite in the subtrata.
Pitzer soils: are underlain with shale or limestone and are in drier climates.
Cho soils: have a carbonatic mineralogy class.
Kavett, Mereta, and Stephen soils: have more than 35 percent silicate clay. In addition, Stephen soils lack a calcic horizon.
Patrick soils: lack a petrocalcic horizon.

GEOGRAPHIC SETTING:
Parent material: calcareous loamy over gravelly alluvium derived from shale, claystone, siltstone, or chalk of Cretaceous Age. These soils formed over thick beds of Uvalde gravel and sand deposited by ancient streams.
Landscape: River Valleys or Dissected Plains
Landform: Risers of ancient stream terraces
Slope: 1 to 20 percent
Mean annual air temperature: 18 to 21 degrees C (64.4 to 69.8 degrees F)
Mean annual precipitation: 737 to 948 mm (29 to 37.3 in)
Frost-free period: 235 to 266 days
Elevation: 117 to 244 m (383.9 to 800.5 ft)
Thornthwaite P-E Index: 42 to 50

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Patrick, Boerne, Lewisville, and Venus series.
They all have cambic horizons and lack petrocalcic horizons. In addition, Boerne soils lack a mollic epipedon. Patrick soils occur on similar surfaces. Boerne, Lewisville, and Venus soils on stream terraces at lower elevations.

DRAINAGE AND PERMEABILITY:
Drainage class: Well;
Permeability class: A horizon is moderate and very slow on the petrocalcic horizon
Runoff: high on slopes less than 1 percent and very high on slopes of 1 to 20 percent.

USE AND VEGETATION: Mainly used for rangeland and as a source of gravel. Native vegetation is live oak and mesquite trees, with grasses such as buffalograss, threeawns, Texas wintergrass, and sideoats grama.

DISTRIBUTION AND EXTENT: This soil occurs primarily in the Texas Blackland Prairies, Northern Part (MLRA 86A) and is of moderate extent and to a minor extent in the Edwards Plateau, Eastern Part (MLRA 81C) and the Grand Prairie (MLRA 85).
