MINAT SERIES

The Minat series consists of very deep, well drained soils formed in colluvium derived from chert, shale and mixed volcanic rocks with some influence from volcanic ash. Minat soils occur on hill and mountain side slopes. Slopes are 15 to 75 percent. The mean annual precipitation is about 230 mm and the mean annual temperature is about 8 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, mesic Xeric Haplocambids

TYPICAL PEDON: Minat very cobbly sandy loam--rangeland. (Colors are for dry soil unless otherwise noted). The soil surface is partially covered with approximately 45 percent gravel and 25 percent cobbles.

A1--0 to 8 cm; pale brown (10YR 6/3) very cobbly sandy loam, brown (10YR 4/3) moist; weak medium platy structure; soft, very friable, slightly sticky and slightly plastic; common very fine and few fine roots; common fine tubular pores; 30 percent gravel and 20 percent cobbles; slightly alkaline (pH 7.8); gradual smooth boundary. (8 to 15 cm thick)

A2--8 to 23 cm; pale brown (10YR 6/3) very gravelly loam, brown (10YR 4/3) moist; weak medium platy structure; soft, very friable, slightly sticky and slightly plastic; common very fine and fine, few medium roots; common fine tubular pores; 35 percent gravel; moderately alkaline (pH 8.0); gradual wavy boundary. (0 to 15 cm thick)

Bw1--23 to 48 cm; pale brown (10YR 6/3) very gravelly loam, brown (10YR 4/3) moist; moderate medium subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; common very fine, few fine and medium roots; common fine tubular pores; 50 percent gravel; moderately alkaline (pH 8.0); gradual wavy boundary. (15 to 30 cm thick)

Bw2--48 to 69 cm; pale brown (10YR 6/3) very gravelly loam, brown (10YR 4/3) moist; moderate medium subangular blocky structure; slightly hard, friable, sticky and plastic; common very fine, few fine and medium roots; few fine tubular pores; 40 percent gravel; effervescent in spots; carbonate coats on undersides of gravel; moderately alkaline (pH 8.4); gradual wavy boundary. (15 to 30 cm thick)

Bqk1--69 to 112 cm; pale brown (10YR 6/3) very gravelly loam, brown (10YR 4/3) moist; weak medium subangular blocky structure; soft, very friable, sticky and plastic; common very fine, few fine and medium roots; 50 percent gravel; l5 percent weakly cemented durinodes; carbonate coats on gravel; strongly effervescent; strongly alkaline (pH 8.6); gradual wavy boundary. (18 to 28 cm thick)

Bqk2--112 to 152 cm; very pale brown (10YR 7/3) very gravelly fine sandy loam, brown (10YR 5/3) moist; massive; slightly hard, very friable, slightly sticky and nonplastic; many very fine roots; 50 percent gravel; 15 percent weakly cemented durinodes; common medium soft carbonate masses and coats on gravel; strongly effervescent; strongly alkaline (pH 8.6)

COMPETING SERIES: These are the Cewat, Darkcanyon, Drinkwater, Lonegrave, Finley, Kiona, Nibbs, Veet, Veta and Wifton soils.

Cewat, Darkcanyon and Lonegrave soils are moderately deep. Drinkwater soils have carbonates within 46 cm. Finley soils have sandy 2C horizons at depths of 50 to 100 cm. Kiona soils have mainly cobbles in the particle-size control section and a mean annual soil temperature of 10 to 12 degrees C. Nibbs soils have secondary lime within 38 cm. Veet soils have a period of appreciable summer moisture for 10 to 20 days in the summer and sola 30 to 50 cm thick. Veta soils have 5 to l5 percent clay in the particle-size control section and are 71 to 100 cm deep to carbonates. Wifton soils have 60 to 80 percent rock fragments in the particle-size control section.

GEOGRAPHIC SETTING: Minat soils are on hill and mountain side slopes. Elevations are 1,375 to 1,895 meters. Slopes are l5 to 75 percent. These soils formed in colluvium derived from chert, shale and mixed volcanic rocks with some influence from volcanic ash. The climate is cool, semiarid with hot, dry summers and cool, moist winters. The mean annual precipitation is 200 to 250 mm, mean annual temperature is 8 to 9 degrees C, and the frost-free season is 90 to 110 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Jung and Locane soils. Jung and Locane are shallow to hard bedrock.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; rapid runoff; moderately high saturated hydraulic conductivity.

USE AND VEGETATION: Livestock grazing and wildlife habitat. The vegetation is mainly Wyoming big sagebrush, spiny hopsage, bottlebrush squirreltail, and Sandberg bluegrass.

DISTRIBUTION AND EXTENT: Central Nevada. These soils are of small extent. MLRA 24.
