Grayco soil and landscape
Soil profile: Typical profile of Grayco sandy loam, 0 to 2 percent slopes. (Soil Survey of Costilla County Area, Colorado; by Alan J. Stuebe, Natural Resources Conservation Service)
Landscape: Typical landscape of Grayco sandy loam, 0 to 2 percent slopes, sown with oats. Ute Mountain is in the background.
The Grayco series consists of very deep, well drained soils that formed in outwash derived from granite, gneiss, and mica schist. Grayco soils are on outwash plains and terraces. Slopes range from 0 to 6 percent. Mean annual precipitation is about 10 inches and the mean annual air temperature is about 41 degrees F.
TAXONOMIC CLASS: Fine-loamy over sandy or sandy-skeletal, mixed, superactive, frigid Ustic Haplargids
Soil moisture: aridic bordering on ustic.
Mean annual soil temperature: 41 to 46 degrees F (5.0 to 7.8 degrees C)
Mean summer soil temperature: 63 to 66 degrees F (17.2 to 18.9 degrees C)
Thickness of argillic horizon: 5 to 20 inches (13 centimeters to 51 centimeters)
Depth to argillic horizon: 2 to 6 inches (5 to 15 centimeters)
Depth to secondary carbonates: 10 to 20 inches (25 to 51 centimeters)
Depth to lithologic discontinuity: 10 to 40 inches (25 to 102 centimeters)
Depth to strongly contrasting particle size class: 10 to 60 inches (25 to 152 centimeters)
Particle-size control section (weighted average):
Clay content: 18 to 27 percent
Sand content: 35 to 60 percent
Silt content: 13 to 47 percent
Rock fragment content: 15 to 60 percent gravel and cobbles
USE AND VEGETATION: These soils are used for livestock grazing and irrigated cropland. Native plants commonly are Wyoming big sage, blue grama, ring muhly, rubber rabbitbrush, and sand dropseed
DISTRIBUTION AND EXTENT: San Luis Valley Area of south-central Colorado; LRR E; MLRA 51. This series is of moderate extent.
