RANGE IN CHARACTERISTICS: Soil Moisture: Intermittently moist in the soil moisture control section May through October and December through February. The soil moisture control section is moist for longer periods of time during the summer than the winter. Soil Temperature: 48 to 59 degrees F. Depth to calcic horizon: 24 to 35 inches. A horizon: Hue: 10YR or 7.5YR Value: 3 to 5 dry, 3 or 4 moist Chroma: 2 to 4 Texture: loam or clay loam Bw horizon: Hue: 5YR, 7.5YR, or 10YR Value: 4 to 6 dry, 3 to 5 moist Chroma: 3 to 6 Texture: loam or clay loam • Bk horizon: Hue: 5YR, 7.5YR, or 10YR Value: 5 to 8 dry, 4 to 7 moist Chroma: 3 to 5 Texture: loam, silty clay loam, clay loam, or sandy clay loam Calcium carbonate: 15 to 50 percent with more than 5 percent visible carbonates. COMPETING SERIES: These are the Abra (AZ), Bighams (AZ), Bowdish (CO), Copeman (WY), Creel (NM), Harvey (NM), Hernandez (NM), Honlu (UT), Numa (CO) and Pultney (CO) series. Abra soils do not have a cambic horizon and have a calcic horizon at a depth of less than 20 inches. Bighams, Bowdish, Creel, and Pultney soils have a lithic or paralithic contact at 20 to 40 inches. Copeman, Harvey, and Honlu soils have a calcic horizon at a depth of less than 24 inches. Hernandez soils are 9 to 12 inches deep to the calcic horizon. Numa soils do not have a cambic horizon and in addition are moist for longer periods in the spring. GEOGRAPHIC SETTING: Darvey soils are on hills, fan terraces and valley fills. Slope is 0 to 5 percent. The soils formed in alluvium derived from calcareous sandstone and shale and limestone. The elevation is 4,500 to 6,500 feet. The mean annual precipitation is 10 to 13 inches, but has ranged to 17 inches in the past. The mean annual soil temperature ranges from 48 to 59 degrees F. The frost-free period is about 150 to 190 days. • (REVISED 9/99) 2.04.9-42
