LOCATION LEMOND MN+IAEstablished Series
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, calcareous, mesic Typic Endoaquolls
TYPICAL PEDON: Lemond loam with a slightly convex slope of less than 1 percent on a glacial outwsh plain in a cultivated field. (Colors are for moist soil unless otherwise noted.)
Ap--0 to 12 inches; black (N 2/0) loam, very dark gray (10YR 3/1) dry; cloddy, friable; strong effervescence; mildly alkaline; abrupt smooth boundary. (8 to 18 inches thick, A1 horizon)
AB--12 to 17 inches; very dark gray (10YR 3/1) loam; weak very fine subangular blocky structure; friable; strong effervescence; mildly alkaline; gradual irregular boundary. (3 to 10 inches thick)
Bg--17 to 24 inches; gray (5Y 5/1) sandy loam; many fine faint olive gray (5Y 5/2) and few fine distinct light olive brown (2.5Y 5/4) and olive (5Y 5/4) mottles; weak fine subangular blocky structure; very friable; few very dark gray (10YR 3/1) tongues; strong effervescence; mildly alkaline; clear wavy boundary. (3 to 14 inches thick)
BCg--24 to 30 inches; olive gray (5Y 5/2) loamy sand; many fine faint olive (5Y 5/3) and many medium distinct light olive brown (2.5Y 5/4) mottles; massive; loose; mildly alkaline; clear wavy boundary. (0 to 14 inches thick)
2Cg--30 to 60 inches; olive gray (5Y 5/2) grading to light olive gray (5Y 6/2) in the lower part, sand; single grained; slight effervescence in the lower part; mildly alkaline grading to moderately alkaline in the lower part.
TYPE LOCATION: Freeborn County, Minnesota; about 3 miles southeast of Geneva; about 2,440 feet north and 200 feet west of southeast corner of sec. 20, T. 104 N., R. 20 W.
RANGE IN CHARACTERISTICS: Thickness of solum and coarse-loamy mantle range from 20 to 40 inches. The mollic epipedon ranges from 14 to 24 inches in thickness. The sola typically lack gravel, but a few pedons contain as much as 5 percent fine gravel of mixed lithology. The control section has less than 18 percent clay and the percent of silt and very fine sand plus twice the percent of clay exceeds 30 percent. These soils typically are mildly or moderately alkaline throughout. The A horizon has hue of 10YR or 2.5Y, value of 2 or 3, and chroma of 1 or is N 2/0 or N 3/0. It is loam, sandy loam, or coarse sandy loam.
The B horizon has hue of 2.5Y or 5Y, value of 4 or 5, and chroma of 1 or 2 with hue of 2.5Y or 1 through 3 with hue of 5Y. It has few through many, faint through prominent mottles. It is loam, sandy loam, or coarse sandy loam in the upper part, and loamy sand, loamy coarse sand, sandy loam, or coarse sandy loam in the lower part.
The 2C horizon has hue of 2.5Y or 5Y. It typically is sand, but it ranges to coarse sand, loamy sand, loamy coarse sand. It contains as much as 35 percent gravel in some pedons and a gravelly substratum is allowed. Some pedons have a loamy 3C horizon below 40 inches.
COMPETING SERIES: These are the Coriff and Fieldon soils in the same family. Coriff soils have a loamy 2C horizon within 40 inches. Fieldon soils have more fine and very fine sand in their solum and C horizon.
GEOGRAPHIC SETTING: Lemond soils have plane or slightly convex slopes with gradient of 0 to 2 percent on rims of depressions and broad flats on glacial outwash plains, valley trains, and lacustrine plains. They formed in glacial outwash or lacustrine sediments consisting of a loamy mantle and underlying sandy sediments. The sediments are Late Wisconsinan in age. Mean annual temperature is 40 to 50 degrees F, and mean annual precipitation is 27 to 32 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dickman and Hanska soils which are members of a hydrosequence with the Lemond soils. The somewhat excessively drained Dickman soils are on higher lying or more sloping terrain. The poorly drained Hanska soils are on nearby level terrain. Lemond soils are associated with Dickinson and Estherville soils and their respective associates in some places.
DRAINAGE AND PERMEABILITY: Poorly drained and very poorly drained. Surface runoff is slow to ponded. Permeability is moderately rapid in the upper part and rapid in the lower part.
USE AND VEGETATION: Primarily drained and cultivated with corn and soybeans the principal crops. Native vegetation was a wet-site community of tall grass prairie.
DISTRIBUTION AND EXTENT: Southern Minnesota and north-central Iowa. Moderately extensive.
