• • • Zimmerman Soil Series Official Soil Series Description The Lino series consists of very deep, somewhat poorly drained soils that formed in sandy glacial outwash or eolian sediments on outwash plains and valley trains. These soils have rapid permeability. Slopes range from 0 to 3 percent. Mean annual precipitation is about 26 inches. Mean annual air temperature is about 44 degrees F. TAXONOMIC CLASS: Mixed, frigid Aquic Udipsamments TYPICAL PEDON: Lino loamy fine sand with a plane slope of 1 percent on a glacial outwash plain in a cultivated field. (Colors are for moist soil unless otherwise stated.) Ap - -0 to 7 inches; dark grayish brown (10YR 4/2) loamy fine sand; weak fine subangular blocky structure; very friable; moderately acid; abrupt smooth boundary. (6 to 10 inches thick) Bw1 - -7 to 16 inches; brown (10YR 5/3) fine sand; many medium faint light brownish gray (10YR 6/2) Fe depletions and distinct yellowish brown (10YR 5/6) Fe concentrations; weak fine and medium subangular blocky structure; very friable; strongly acid; gradual wavy boundary. Bw2 - -16 to 45 inches; light brownish gray (10YR 6/2) fine sand; many coarse prominent reddish brown (5YR 5/3) and yellowish red (5YR 4/6) Fe concentrations; single grain; loose; Fe concentrations mostly vertically oriented and very weakly cemented when dry; moderately acid; gradual wavy boundary. (Combined thickness of the Bw horizons is 18 to 40 inches.) C - -45 to 60 inches; pale brown (10YR 6/3) fine sand; many coarse prominent reddish brown (5YR 5/4 and 4/3) and faint brown (10YR 5/3) Fe concentrations and distinct gray (10YR 6/1) Fe depletions; massive breaking readily to single grained; very friable; reddish brown and brown Fe concentrations weakly cemented when dry; slightly acid. TYPE LOCATION: Anoka County, Minnesota; about 3 miles north and 1 mile east of Circle Pines; about 2,330 feet west and 1,630 feet north of the southeast corner of sec. 7, T. 31 N., R. 22 W.; USGS Circle Pines quadrangle; lat. 45 degrees 11 minutes 12 seconds N. and long. 93 degrees 7 minutes 52 seconds W., NAD27 RANGE IN CHARACTERISTICS: Depth to free carbonates ranges from 50 to 100 inches or more. The series control section and C horizon do not have rock fragments. Quartz comprises about 70 to 85 percent of the sand fraction. Typically, the particle -size control section averages fine sand, but sand is within the range. The content of coarse and very coarse sand ranges from 0 to 5 percent in the particle - size control section. The Ap horizon has hue of 10YR, value of 2 to 4, and chroma of 1 or 2. It is loamy fine sand, loamy sand, fine sandy loam, or fine sand. It is strongly acid or moderately acid. Some pedons have an E horizon ranging to as much as 6 inches in thickness with hue of 10YR, value of 4 or 5, and chroma of 2.
