TYPE LOCATION: Benewah County, Idaho; about 600 feet north and 45 feet east of center of section 10, T.44N., R.5W.
RANGE IN CHARACTERISTICS: The sola range from 40 to 60 inches thick. The mean annual soil temperature ranges from 45 degrees to 47 degrees F. Base saturation is less than 75 percent in part of the upper profile.
The A1 horizon has hue of 10YR or 2.5Y, value of 5 or 6 dry, 2 through 4 moist, and chroma of 1 through 4 dry, 1 through 3 moist. It is medium acid through neutral.
The Bt horizon has value of 6 or 7 dry, 3 or 4 moist and chroma of 2 through 4 dry, 3 or 4 moist. It is silt loam or silty clay loam. This horizon is medium acid through neutral in the upper part and slightly acid or neutral in the lower part.
COMPETING SERIES: These are the Benewah and Carlinton series in the same family and Ketchly, McEwan, and Wintoner series. Benewah soils have hue of 7.5YR or 5YR in the B2t horizon. Carlinton soils are very strongly acid or strongly acid in the upper part of the control section. Ketchly, McEwan, and Wintoner soils lack an A2 horizon and are well drained.
GEOGRAPHIC SETTING: The Lovell soils are in the concave positions or depressions in alluvial bottomlands. They formed in mixed alluvium from loess, basalt medisedimentary rocks, and volcanic ash that has accumulated in bottoms. Elevations range from 2,000 to 2,800 feet. Slope gradients range from 0 to 2 percent. The mean annual precipitation is 18 to 23 inches. The frost-free period is 100 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Latahco and Moctileme soils. Latahco soils have a mollic epipedon. Moctileme soils ave medial mineralogy.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; very slow runoff; slow permeability; overflow occurs in 3 out of 5 years with a perched watertable at less than 2 feet in early spring.
USE AND VEGETATION: Most areas are under cultivation of small grain, hay and pasture. The natural vegetation is mainly ponderosa pine and black hawthorne.
DISTRIBUTION AND EXTENT: Northern Idaho and eastern Washington. The series is of small extent.
