Ard soil and landscape
Soil profile: Typical profile of Ard silt loam in an area of Clementsville-Ard complex, 4 to 12 percent slopes. (Soil Survey of Teton Area, Idaho and Wyoming; by Carla B. Rebernak, Natural Resources Conservation Service)
Landscape: Harvested grainfield in an area of Clementsville-Ard complex, 4 to 12 percent slopes. Clementsville and similar soils make up about 70 percent and Ard and similar soils make up about 20 percent of this map unit. Ard soils are on mountain slopes and loess hills and have slopes of 4 to 12 percent.
The Ard series consists of moderately deep, well drained soils that formed in rhyolite residuum with loess influence. The mean annual precipitation is about 530 mm and the mean annual air temperature is about 3.3 degrees C.
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive Calcic Haplocryolls
Mollic epipedon thickness: 25 to 40 cm
Depth to bedrock: 50 to 100 cm
Depth to the calcic horizon (2Bk horizon): 25 to 40 cm
Particle size control section rock fragments: 0 to 35 percent
Particle size control section total clay: 7 to 18 percent
Reaction: neutral to strongly alkaline
Soil moisture regime: xeric, dry for 45to 60 consecutive days
Mean annual soil temperature: 3.9 to 7.2 degrees C. (cryic soil temperature regime)
Mean summer soil temperature: 10.0 to 15.0 degrees C.
USE AND VEGETATION:
Major uses: Non-irrigated winter and spring wheat, barley, and rangeland
Dominant native vegetation: mountain big sagebrush, Idaho fescue, bluebunch wheatgrass, tapertip hawksbeard
DISTRIBUTION AND EXTENT:
Distribution: Southeastern Idaho, MLRA 13
Extent: the series is not extensive
