Benchley soil and landscape
Soil profile: Benchley clay loam. An accumulation of organic matter is evident in the thick, dark surface layer. (Soil Survey of Robertson County, Texas; by Harold W. Hyde, Natural Resources Conservation Service)
Landscape: Soybeans on an area of Benchley clay loam, 1 to 3 percent slopes. (Soil Survey of Lee County, Texas; by Maurice R. Jurena, USDA-Natural Resources Conservation Service)
These nearly level to moderately sloping soils are on ridges on dissected plains. Slope ranges from 0 to 8 percent but are dominantly 1 to 3 percent. Typically cultivated crops are cotton, grain sorghum, corn, soybeans and small grain. Bermudagrass pastures are common. Native vegetation includes little bluestem, big bluestem, Indiangrass, brownseed paspalum and various forbes.
TAXONOMIC CLASS: Fine, smectitic, thermic Udertic Argiustolls
Soil Moisture: An ustic soil moisture regime. The soil moisture control section is dry in some or all parts for more than 90 days in normal years.
Soil Depth: 152 to more than 203 cm (60 to more than 80 in).
Rock fragments: amount-0 to 5 percent; kind-ironstone nodules, or sandstone; roundness-rounded or angular; cementation-indurated; size-gravel.
Thickness of mollic epipedon: 33 to 48 cm (13 to 19 in)
Depth to argillic horizon: 15 to 33 cm (6 to 13 in)
Depth to slickensides: 38 to 74 cm (15 to 29 in)
Depth to secondary carbonates: 124 to 203 cm (49 to 80 in)
Depth to redox features (when present): 15 to 23 cm (6 to 9 in)
Depth to gypsic horizon (when present): 157 to 203 cm (62 to 80 in)
Depth to densic material (when present): 152 to 203 cm (60 to 80 in)
Particle size control section: 35 to 55 percent
Clay content: 25 to 100 cm (10 to 40 in)
Surface features: When dry, cracks about 1 cm (1/2 in) wide are in the argillic horizon and extend to a depth of 30 cm or more (12 in or more).
DISTRIBUTION AND EXTENT: The Blackland Prairies of East Central Texas (MLRA 86B). The series is of moderate extent.
