BADHAP SERIES


The Badhap series consists of very deep, well drained soils that formed in colluvium and residuum derived from quartzite with a component of loess. Badhap soils are on hills, mountains, and ridges. Slopes are 15 to 75 percent. The mean annual precipitation is about 460 mm and the mean annual temperature is about 4 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive Pachic Haplocryolls

COMPETING SERIES: These are Baconcamp, Behanco, Behanin, Belsac, Boydhollow, Bullrey, Busterback, Croesus, Dressel, Gateview, Goodski, Hapgood, Harcany, Hobacker, Lionhead, Lolon, Marcetta, Mundos, Nagitsy, Namela, Nazaton, Papaspila, Parkcity, Poleline, Povey, Snacreek, Snopoc, Splitbutte and Tonigut series.

Baconcamp soils are moderately deep. Behanco soils are deep. Behanin soils have 40 to 60 cm thick mollic epipedons and mean annual soil temperasture is 1 to 4 degrees C. Belsac and Goodski soils have a paralithic contact within 100 cm. Bullrey soils have C horizons with value of 7 dry and 5 moist and have medium or slightly acid reaction. Boydhollow, Busterback, Gateview, Harcany, Parkcity and Snacreek, Snopoc soils have less than 18 percent clay in the particle-size control section. Dressel soils have Udic soil moisture regime, mean annual soil temperature of 2 to 4 degrees C, and have fragments of dominantly sandstone lithology. Marcetta soils have E horizons. Nazaton soils have O horizons, a mean annual soil temperature of 7 to 8 degrees C, and have fragments of dominantly granitics lithology. Hobacker, Lionhead, Mundos and Tonigut soils are calcareous within 100 cm. Croesus, Hapgood, Nagitsy, Namela, Poleline and Splitbutte soils have bedrock within 150 cm. Lolon soils have loose sand at a depth of less than 100 cm. Papaspila soils have summer soil temperatures of 7 to 8 degrees C and an udic soil moisture regime. Povey soils have a cambic horizon and 10 to 20 percent clay in the control section.

GEOGRAPHIC SETTING: Badhap soils are on smooth to concave hills, mountains, and ridges with predominantly north aspects. They formed in colluvium and residuum derived from quartzite with a component of loess. Slopes are 15 to 75 percent. Elevations range from 2,075 to 3,200 meters. Climate is semiarid with cold wet winters and warm, mostly dry summers. The mean annual precipitation is 400 to 500 mm that comes largely as winter snow. Additional moisture may be derived as a result of snow accumulation through drifting in the area. The mean annual temperature is 3 to 6 degrees C and the frost-free period is 30 to 60 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Jonlake, Osditch, and Topeki soils. Jonlake and Topeki soils have lithic contacts within 50 cm. Osditch soils have ochric epipedons and cambic horizons.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; medium to very high surface runoff; moderately high saturated hydraulic conductivity.

USE AND VEGETATION: Badhap soils are used mainly for livestock grazing and wildlife habitat. The potential vegetation is mountain big sagebrush, snowberry, bluebunch wheatgrass, slender wheatgrass and muttongrass.

DISTRIBUTION AND EXTENT: Eastern Nevada; these soils are not extensive; MLRA 28A.
