Etoile soil series
Note: The left side of the photo exhibits natural soil structure. The right side has been smoothed.
Profile of Etoile loam in an area of Etoile loam, 1 to 5 percent slopes. Etoile soils have clayey subsoils, and formed over densic material. (Soil Survey of San Augustine and Sabine Counties, Texas; by Kirby Griffith, Natural Resources Conservation Service)
The Etoile series consists of soils that are deep to shale. They are moderately well drained and very slowly permeable. These soils are on broad, very gently sloping to moderately steep interfluves. The slope is dominantly less than 5 percent but ranges from 1 to 20 percent.
TAXONOMIC CLASS: Fine, smectitic, thermic Vertic Hapludalfs
Solum thickness ranges from 40 to 60 inches. The particle-size control section is clayey with a weighted average clay content of 40 to 60 percent. Depth to calcium carbonate accumulations ranges from 25 to 50 inches. The soil cracks when dry. Cracks 1/2 inch or more wide in the top of the argillic horizon extend to a depth of more than 12 inches for 60 to 90 cumulative days in normal years. Slickensides and/or wedge shaped peds are in some subhorizon more than 6 inches thick within the argillic horizon. The combined thickness of the A and E horizons is dominantly less than 10 inches, however, the depth ranges from 3 inches on subsoil crests to 14 inches in some subsoil troughs. Some pedons do not have an E horizon, and in most areas that have been cultivated the E horizon has been incorporated into the Ap horizon. Redox features are considered relic or lithochromic.
USE AND VEGETATION: Used mainly for woodland. Native species are shortleaf and loblolly pine, red oak, and sweetgum. A few areas are used for native or improved pasture.
DISTRIBUTION AND EXTENT: Western Coastal Plain (MLRA 133B) in eastern Texas. The series is of moderate extent.
