Loneoak soil series

Soil profile of Loneoak loamy sand in an area of Loneoak-Campair complex, 0 to 5 percent slopes. This deep, moderately well drained soil is located on undulating plains of the Hickory Sandstone Formation. The sandy surface ranges from 50 to 90 centimeters thick. The clayey subsoil contains 30 to 50 percent clay. (Soil Survey of Mason County, Texas; by Julia A. McCormick, Natural Resources Conservation Service)

 

The Loneoak series consists of very deep, moderately well drained soils formed in materials derived from Cambrian-age sandstone. These soils are on nearly level to very gently sloping undulating plains and footslopes of ridges. Slope are 0 to 5 percent. Mean annual air temperature is about 18 degrees C (66 degrees F), and mean annual precipitation is about 686 mm (27 in).

 

TAXONOMIC CLASS: Clayey, mixed, active, thermic Arenic Paleustalfs

 

Solum thickness and depth to sandstone bedrock: 150 to 180 cm (60 to 71 in)

Arenic feature: 50 to 90 cm (20 to 35 in)

Paralithic bedrock: 150 to 180 cm (60 to 71 in)

Lithic bedrock: 160 to 195 cm (63 to 77 in)

Particle-size control section (weighted average):

Clay content: 35 to 45 percent

Redox features: Mainly relict; however, in one to three years out of ten the soil is saturated for periods long enough to have reducing conditions. These soils are marginal to Aquic Arenic Paleustalfs.

 

DRAINAGE AND PERMEABILITY: Moderately well drained and slow permeability. Runoff is low. These soils may have a shallow perched water table above the Bt horizon and/or above the sandstone bedrock during unusually wet years for 4 to 10 weeks in duration. Typically, there are one to three wet years in a ten year period.

 

USE AND VEGETATION: Mainly used as improved pasture and cropland. Native vegetation consists of blackjack and post oak with an understory of little bluestem, big bluestem, Indiangrass, purpletop, sand lovegrass, silver bluestem, tall dropseed, Scribner's panicum and greenbriar.

 

DISTRIBUTION AND EXTENT: Central Texas. Southwest Plateaus and Plains Range and Cotton Region, LRR-I; MLRA 82A-Central Basin of Texas. The series is of moderate extent. This soil was previously included with the Demona series.
