Trail soil series

Soil profile: A representative soil profile of the Trail series in an area of Monue-Trail-Nepalto complex, 1 to 6 percent slopes. (Soil Survey of Glen Canyon Recreation Area, Arizona and Utah; by Michael W. Burney, Natural Resources Conservation Service)

 

The Trail series consists of very deep, well drained and somewhat excessively drained soils that formed in stratified alluvium weathered dominantly from sandstone, siltstone, limestone and mudstone. Trail soils are on floodplains and alluvial fans and have slopes of 0 to 8 percent. Elevations range from 3,800 to 6,200 feet. The mean annual precipitation is about 8 inches and the mean annual air temperature is about 54 degrees F.

 

TAXONOMIC CLASS: Sandy, mixed, mesic Typic Torrifluvents

 

Soil Moisture: Intermittently moist in some part of the soil moisture control section during July-September and December-February. Driest during May and June. Typic aridic soil moisture regime.

Soil Temperature: 51 to 61 degrees F.

Rock Fragments: less than 15 percent gravel

Reaction: slightly alkaline to strongly alkaline

Calcium carbonate: effervescent from at depth of less than 10 inches to more than 40 inches

Salinity: none to slightly saline

Sodicity: none to slightly sodic

 

USE AND VEGETATION: Trail soils are used for livestock grazing and irrigated cropland. The present vegetation is cottonwood, salt cedar, willow, Russian thistle, camelthorn, fourwing saltbush, and sand dropseed.

 

DISTRIBUTION AND EXTENT: Northern Arizona, southern Colorado, northern New Mexico and southern Utah. This series is not extensive. MLRA 35 and 36. Use in MLRA 70C is not allowed.
