Darco soil and landscape
A representative soil profile of Darco loamy fine sand. (Soil Survey of Shelby County, Texas; by Kirby Griffith, Natural Resources Conservation Service)
Landscape: Coastal pasture in an area of Darco loamy fine sand, 1 to 8 percent slopes. Most areas are used for pine production; some smaller areas are used for pasture or residential uses.
The Darco series consists of very deep, somewhat excessively drained, moderately permeable soils that formed in sandy and loamy residuum from Southern Coastal Plain marine deposits of the Carrizo Sand, Queen City Sand, and Sparta Sand Formations. These gently sloping to steep soils are on uplands. Slopes range from 1 to 25 percent. Mean annual precipitation ranges from 1016 to 1270 mm (40 to 50 in) and the mean annual air temperature ranges from 17 to 20 degrees C (63 to 68 degrees F).
TAXONOMIC CLASS: Loamy, siliceous, semiactive, thermic Grossarenic Paleudults
Soil Moisture: Udic soil moisture regime. The soil moisture control section is moist in some or all parts for more than 275 days in normal years, July and August are the driest months, while November to May are the wettest months.
Mean annual soil temperature range: 18 to 21 degrees C (64 to 70 degrees F).
Solum thickness: Greater than 203 cm (80 in)
Particle-size control section (weighted average):
Clay content: 12 to 35 percent
USE AND VEGETATION: Most of the soil is used for pasture or woodland. Pastures are mainly in coastal bermudagrass or weeping lovegrass. Native trees include loblolly pine, shortleaf pine, red oak, and hickory. Watermelons, peanuts, small grain for grazing, and vegetables are grown in some areas.
DISTRIBUTION AND EXTENT: Eastern Texas, Arkansas, and Mississippi. The series is extensive. These soils were formerly included in the Lakeland and Troup series. The series was updated in 2002 to allow value 6 in the Bt horizon and to allow clay loam texture below 60 inches deep. The series was updated in 2004 to allow 7.5YR hue in the E and EB horizons.
