(6 to 24 inches thick)
3C--44 to 60 inches; variegated gray (10YR 5/2), light brownish gray (10YR 6/2), yellowish brown (10YR 5/8), and yellow (10YR 7/8) very gravelly loamy sand; massive; very hard, very firm, strongly consolidated, nonsticky and nonplastic; 40 percent gravel and 5 percent cobbles; very strongly acid (pH 4.6).
TYPE LOCATION: Lane County, Oregon; 0.3 mile northwest of Elmira High School; northwest 1/4 northwest 1/4, sec. 24, T. 17 S., R. 6 W.
RANGE IN CHARACTERISTICS: The annual soil temperature ranges from 54 to 56 degrees F. The soil is saturated and has a temporary water table during the winter and spring. Depth to loamy sand ranges from 24 to 36 inches. Depth to the very gravelly horizon ranges from 40 to 60 inches.
The A horizon has value of 2 or 3 moist and 4 or 5 dry.
The Bw horizon has hue of 10YR or 7.5YR, value of 4 or 5 moist, 6 or 7 dry, and chroma of 1 or 2 moist and dry. It is loam or fine sandy loam.
The C horizon has hue of 10YR to 5YR, value of 6 or 7, and chroma of 2 or 3. It commonly is fine sandy loam but ranges to loam and is 10 to 18 percent clay. Mottles are distinct or prominent.
The 2C horizon is 0 to 10 percent gravel.
The 3C horizon is very gravelly loamy sand or very gravelly sandy loam, and is 35 to 60 percent coarse fragments. It is weakly to strongly consolidated.
COMPETING SERIES: This is the Koch series in another family. Koch soils have an umbric epipedon more than 24 inches thick.
GEOGRAPHIC SETTING: Noti soils are in swales and narrow drainageways on terraces. Elevations range from 300 to 800 feet. Slopes are 0 to 3 percent. The soils are in a cool and subhumid climate with mean annual precipitation ranging from 40 to 60 inches. The mean January temperature is 40 degrees F, the mean July temperature is 67 degrees F, and the mean annual temperature is 52 to 54 degrees F. The frost-free period is 165 to 210 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dayton, Holcomb, Linslaw, Natroy, Salkum, and Veneta soils. All of these soils are fine or very-fine textured and all except Natroy soils have an argillic horizon. Natroy soils are very fine-textured and crack to depths of 20 inches or more. Salkum and Veneta soils are well or moderately well drained.
DRAINAGE AND PERMEABLILITY: Poorly drained; very slow runoff or ponded; slow permeability.
USE AND VEGETATION: This soil is used for pasture and forage crops. Native vegetation is Oregon white oak, Oregon ash, rose, hazel, blackberry, sedges, and grasses.
DISTRIBUTION AND EXTENT: Southwestern terraces of the Willamette Valley, Oregon. The series is of small extent.
