Topdeck soil series
A representative soil profile of the Topdeck series. The Topdeck series consists of shallow, well drained soils that formed in colluvium and residuum from basalt, breccia, and andesite. (Supplement to the Soil Survey of Los Angeles County, California, Southeastern Part; by Randy L. Riddle and Christopher “Kit” Paris, Natural Resources Conservation Service)
These soils are on marine terraces and side slopes of hills and mountains. Slopes range from 2 to 100 percent. The mean annual precipitation is about 457 millimeters (18 inches) and the mean annual temperature is about 19 degrees C (66 degrees F).
TAXONOMIC CLASS: Loamy, mixed, superactive, thermic Lithic Argixerolls
Mean annual soil temperature: 61 to 66 degrees F. (16 to 18 degrees C.) Soil moisture: Soil is dry from mid-June through mid-November.
Depth to lithic bedrock: 10 to 20 inches (25 to 50 centimeters).
Organic matter: 1 to 2 percent throughout, decreasing with depth.
USE AND VEGETATION: Wildlife habitat, recreation and building site development. Vegetation is coastal sage brush, buckwheat and needle grass.
DISTRIBUTION AND EXTENT: Santa Barbara County, California. The soil is of limited extent and found only on the Channel Islands. MLRA 20.
