Silawa soil series
A representative soil profile of the Silawa soil series. (Soil Survey of Robertson County, Texas; by Harold W. Hyde, Natural Resources Conservation Service),
The Silawa series consists of very deep, well drained, moderately permeable soils that formed in sandy and loamy sediments. These soils are on nearly level to strongly sloping terraces. Slopes range from 0 to 12 percent.
TAXONOMIC CLASS: Fine-loamy, siliceous, semiactive, thermic Ultic Haplustalfs
Solum thickness ranges from 40 to 60 inches. The percent clay decreases by 20 percent or more of the maximum at a depth of 30 to 60 inches. Clay content of the particle size control section ranges from 18 to 35 percent. Siliceous pebbles range from 0 to 10 percent throughout the A, E, and Bt horizons. Base saturation throughout the argillic varies from 35 to 70 percent.
USE AND VEGETATION: Most areas are used for tame pasture or native range. A few areas are used for truck crops. Native vegetation is mainly post oak and blackjack oak with an understory of mid and tall grasses.
DISTRIBUTION AND EXTENT: Central Texas and possibly southern Oklahoma. The series is moderately extensive. These soils were formerly included with the Konawa series.
